[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] In the present invention, descriptions such as "first" and "second" are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions of various embodiments may be combined with each other, but this must be based on the fact that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0026] An embodiment of the present invention provides a manual adjustment method for the bending roll of a cold rolling mill. The cold rolling mill includes multiple frames and monitors. Each frame includes a bending roll corresponding to the frame. The bending roll includes a working roll bending roll and an intermediate roll bending roll. The cold rolling mill in all the following embodiments is based on the Shougang Cold Rolling 1850 fully continuous five-frame six-roll CVC rolling mill as an example. The cold rolling mill includes five frames, namely S1 frame, S2 frame, S3 frame, S4 frame and S5 frame. The relative position of the working roll bending roll operating rod and the intermediate roll bending roll operating rod of each frame is referenced. Figure 1 shown.

[0027] refer to Figure 2 As shown, the manual adjustment method of the bending roll of the cold rolling mill includes the following steps:

[0028] S201: Obtain a first plate shape judgment result from a monitor, and obtain interface parameters, where the interface parameters include a set value and an actual value of a bending force of each work roll and intermediate roll.

[0029] It should be noted that the plate shape refers to the strip shape produced by the cold rolling mill. The first plate shape judgment result may be double-sided wave, middle wave or normal. The shape of double-sided wave and middle wave can refer to Figure 3 As shown, the first plate shape judgment result is normal, which means that there are no double-sided waves or middle waves.

[0030] As shown in Table 1, the cold rolling mill includes 5 stands, and the interface parameters include the set values ​​and actual values ​​of the bending forces of the working roll bending and the intermediate roll bending corresponding to the S1 to S5 stands. For example, the interface parameters include the set value of 23% of the bending force of the working roll bending of the S1 stand, and the actual value of 33% of the bending force of the intermediate roll bending of the S2 stand.

[0031] It should be noted that after the cold rolling mill pre-sets the current rolled coil, a set value for the bending roll force is given. When the equipment capacity, steel specifications, and rolling conditions cannot reach the pre-set parameters, the set value and actual value of the bending roll force are different, and manual adjustment is required.

[0032] Table 1:

[0033]

[0034] refer to Figure 1 As shown, the bending force can be increased by operating the intermediate roll bending operating rod upwards, and the bending force can be decreased by operating the intermediate roll bending operating rod downwards. The bending force can be increased by operating the working roll bending operating rod upwards, and the bending force can be decreased by operating the working roll bending operating rod downwards.

[0035] It should be noted that the reference Figure 4 As shown, the internal structure of the bending roll includes an upper roll and a lower roll. The bending force can be adjusted by controlling the position of the upper and lower rolls. The bending forces of the work rolls and intermediate rolls in Table 1 are expressed in percentages. This is a method of expressing the magnitude of the bending force by the relative position of the upper and lower rolls. In addition, it is assumed that the bending force adjustment range of the work rolls of the cold rolling mill in all embodiments of the present invention is -40% to +100%, and the bending force adjustment range of the intermediate rolls is -60% to +100%. The numbers represent the relative magnitude of the force, and the positive and negative signs indicate the direction of the force.

[0036] S202: Based on the first plate shape judgment result, a plate shape adjustment plan for the bending roller is obtained.

[0037] It is understandable that, based on the first shape determination result, the shape adjustment scheme for the bending roller is obtained, including the following three possibilities:

[0038] First, if the first plate shape judgment result indicates that the plate shape of the stand is double-sided corrugation, the bending force of the work roll and intermediate roll of the stand is increased. Referring to Tables 2 and 3, the plate shape at the exit of the S4 stand and the exit of the S5 stand is double-sided corrugation. The plate shape adjustment plan is to make multiple micro-adjustments to the bending rolls of the S4 and S5 stands, that is, to make multiple micro-adjustments to the bending force of the work roll and the intermediate roll of the S4 stand, as well as to make micro-adjustments to the bending force of the work roll and the intermediate roll of the S5 stand. After the plate shape defect is eliminated, the bending force adjustment of the S4 and S5 stands is no longer considered in the subsequent parameter adjustment plan.

[0039] Table 2:

[0040]

[0041] Table 3:

[0042] Plate shape problem Adjustment method Adjustment principle Double-sided waves The bending force of the working roll and the intermediate roll increase slightly By changing the bending force of the bending roller Middle Wave The bending force of the working roll and the intermediate roll are slightly reduced By changing the bending force of the bending roller

[0043] It should be noted that the adjustment of the bending roll force of the S5 frame is applied in the automatic control of the plate shape. First, select the automatic adjustment mode. When the plate shape at the outlet of the S5 frame is normal, no adjustment is performed. When middle waves or double-sided waves appear at the outlet of the S5 frame, the automatic control of the plate shape of the S5 frame should be turned off first, and then the bending roll force of the S5 frame should be adjusted manually.

[0044] It should be noted that fine-tuning is set for situations where the deviation range of the bending roll force is small. The operation method is to trigger the operating rod and then quickly withdraw it. The bending roll force after fine-tuning has the effect of slightly increasing or decreasing. The bending roll force changes to increase by 1% to 2% or decrease by 1% to 2%.

[0045] The second method is to reduce the bending forces of the work rolls and intermediate rolls of the stand if the first shape determination result indicates that the shape of the stand is medium-wavy. As shown in Table 4, the shape of the plate at the outlet of stand S1 is medium-wavy, that is, the shape of the plate from S1 to S2 is medium-wavy. The shape adjustment plan involves multiple micro-adjustments to the bending rolls of stand S1, that is, multiple micro-adjustments to reduce the bending forces of the work rolls and the intermediate rolls. Once the shape defect is eliminated, the bending force adjustment of stand S1 is no longer considered in the subsequent parameter adjustment plan.

[0046] The third method is to make no adjustment if the first plate shape judgment result is normal.

[0047] Table 4:

[0048]

[0049] S203: Based on the interface parameters, a parameter adjustment scheme for the bending roll is obtained.

[0050] It can be understood that the method for obtaining the parameter adjustment scheme of the bending roll based on the interface parameters includes the following steps S2031-S2032:

[0051] S2031: Based on the interface parameters, a parameter deviation value is obtained, where the parameter deviation value includes a deviation between an actual value and a set value of the bending force of each working roll and intermediate roll.

[0052] It should be noted that the deviation between the actual value and the set value includes the difference between the actual value and the set value. Referring to Table 2, the parameter deviation of the working roll bending force of the S1 frame is 9%, the parameter deviation of the intermediate roll bending force of the S2 frame is -7%, and the parameter deviation of the working roll bending force of the S4 frame is -2%.

[0053] S2032: Divide the parameter deviation values ​​according to the magnitude of the parameter deviation to obtain a parameter adjustment plan for the bending roll.

[0054] It can be understood that, assuming that Table 2 shows the interface parameters of the cold rolling mill, the parameter deviation values ​​are divided according to the size of the parameter deviation, and the method for obtaining the parameter adjustment scheme of the bending roll includes the following steps 1 to 7:

[0055] Step 1: In the parameter deviation value, the working roll bending force corresponding to the parameter deviation within the preset first working roll deviation range is divided into a non-adjustment sub-scheme.

[0056] It should be noted that the non-adjustment sub-scheme means that the bending force of the bending roll does not need to be adjusted.

[0057] It should be noted that the deviation range of the first working roll includes -2% to 2%. Therefore, referring to Table 2, there is no case where the magnitude of the parameter deviation is within the preset first working roll deviation range.

[0058] Step 2: In the parameter deviation value, the intermediate roll bending force corresponding to the parameter deviation being within the preset first intermediate roll deviation range is divided into a non-adjustment sub-scheme.

[0059] It should be noted that the deviation range of the first intermediate roller includes -5% to 5%. Therefore, referring to Table 2, there is no case where the magnitude of the parameter deviation is within the preset first intermediate roller deviation range.

[0060] It is understandable that not adjusting the sub-scheme also includes the following two situations:

[0061] The first option is to classify the work roll bending force and intermediate roll bending force of the last stand with normal plate shape as a non-adjustment sub-scheme. Specifically, the first option means that when the plate shape at the outlet of stand S5 is normal, the work roll bending force and intermediate roll bending force of stand S5 do not need to be adjusted. Referring to Table 2, the work roll bending force and intermediate roll bending force of stand S5 are classified as a non-adjustment sub-scheme.

[0062] The second option is to classify the work roll bending force and intermediate roll bending force corresponding to the stand exit when the plate shape returns to normal as a non-adjustment sub-option. Specifically, the second option means that the work roll bending force and intermediate roll bending force of stands S1 to S5 do not need to be adjusted after the plate shape returns to normal. The above-mentioned normal plate shape refers to the situation where the plate shape at the exit of stands S1 to S5 has double-sided or middle waves and multiple micro-adjustments have been made to eliminate double-sided or middle waves at the exit of stands S1 to S5. Therefore, the work roll bending force and intermediate roll bending force of stand S4, where the plate shape has returned to normal, are classified as a non-adjustment sub-option.

[0063] Step 3: In the parameter deviation value, the working roll bending force corresponding to the parameter deviation being within the preset second working roll deviation range is divided into fine-tuning sub-schemes.

[0064] It should be noted that the fine-tuning sub-scheme refers to a fine-tuning of the bending force of the bending roll.

[0065] It should be noted that the deviation range of the second working roll includes -5% to -2% and 2% to 5%. Therefore, referring to Table 2, there is no case where the size of the parameter deviation is within the preset second working roll deviation range.

[0066] Step 4: In the parameter deviation value, the intermediate roll bending force corresponding to the parameter deviation within the preset second intermediate roll deviation range is divided into fine-tuning sub-schemes.

[0067] It should be noted that the second intermediate roll deviation ranges include -10% to -5% and 5% to 10%. Referring to Table 2, situations where the parameter deviation falls within the preset second intermediate roll deviation range include: a 9% parameter deviation for the intermediate roll bending force of the S1 stand, and a -7% parameter deviation for the intermediate roll bending force of the S2 stand. Therefore, the intermediate roll bending forces of both the S1 and S2 stands are classified as fine-tuning sub-schemes.

[0068] Step 5: In the parameter deviation value, the working roll bending force corresponding to the parameter deviation being within the preset third working roll deviation range is divided into a continuous adjustment sub-scheme.

[0069] It should be noted that the continuous adjustment sub-scheme refers to the continuous adjustment of the bending roll force. Continuous adjustment is designed for situations where the bending roll force has a large deviation range to improve adjustment efficiency. Its operation method is to continuously move the operating rod. The continuous adjustment of the bending roll force changes in two directions: increasing and decreasing. The bending roll force change rate is 4% to 6% per second.

[0070] It should be noted that the third work roll deviation range includes greater than 5% or less than -5%. Referring to Table 2, situations where the parameter deviation falls within the preset third work roll deviation range include: a parameter deviation of 9 for the work roll bending force of stand S1, a parameter deviation of 6 for the work roll bending force of stand S2, and a parameter deviation of -25 for the work roll bending force of stand S3. Therefore, the work roll bending forces of stand S1, stand S2, and stand S3 are classified as continuous adjustment sub-schemes.

[0071] Step 6: In the parameter deviation value, the intermediate roll bending force corresponding to the parameter deviation within the preset third intermediate roll deviation range is divided into a continuous adjustment sub-scheme.

[0072] It should be noted that the third intermediate roll deviation range includes greater than 10% or less than -10%. Referring to Table 2, situations where the parameter deviation falls within the preset third intermediate roll deviation range include a parameter deviation of -16 for the intermediate roll bending force of the S3 stand. Therefore, the intermediate roll bending force of the S3 stand is divided into a continuous adjustment sub-scheme.

[0073] Step 7: Combine the non-adjustment sub-plan, the fine-tuning sub-plan, and the continuous adjustment sub-plan into a parameter adjustment plan.

[0074] It should be noted that, as shown in Table 2, the parameter adjustment options include: a no-adjustment sub-option, which adjusts the work and intermediate roll bending forces of stand S4 and stand S5 after the plate shape returns to normal; a fine-tuning sub-option, which adjusts the intermediate roll bending forces of stand S1 and stand S2; and a continuous adjustment sub-option, which adjusts the work and intermediate roll bending forces of stand S1, stand S2, stand S3, and stand S3.

[0075] It should be noted that the methods for adjusting the working roll bending force and the intermediate roll bending force include micro-adjustment and continuous adjustment, the purpose of which is to adjust to a range where the deviation is small and does not affect production.

[0076] S204: According to the bending roll adjustment effect, the plate shape adjustment plan and the parameter adjustment plan are recombined to obtain an effect adjustment plan.

[0077] It can be understood that, assuming that Table 2 shows the interface parameters of the cold rolling mill, according to the bending roll adjustment effect, the plate shape adjustment scheme and the parameter adjustment scheme are recombined to obtain the effect adjustment scheme, which includes the following steps 1 to 4:

[0078] Step 1: Divide the bending roll adjustment effect into a solution for solving a bending roll parameter problem of a frame into a first effect sub-solution.

[0079] It should be noted that the solution to the problem of a bending roll parameter of a frame refers to a solution in which one bending roll force of a frame needs to be adjusted, while the other bending roll force does not need to be adjusted.

[0080] It should be noted that, according to Table 2, the parameter adjustment scheme obtained from Table 2, and the plate shape adjustment scheme obtained from Table 2, it can be seen that there is no specific scheme in the first effect sub-scheme.

[0081] Step 2: Divide the bending roll adjustment effect as a solution to the plate shape and parameter problems of a frame into a second effect sub-solution.

[0082] It should be noted that the solution to the plate shape and parameter problems of a frame refers to the solution to the existence of double-sided waves or middle waves at the frame outlet, and the solution that requires adjustment of the bending force of the working rolls and the bending force of the intermediate rolls of a frame.

[0083] It should be noted that, according to Table 2, the parameter adjustment scheme obtained through Table 2, and the plate shape adjustment scheme obtained through Table 2, it can be known that the second effect sub-scheme includes reducing the working roll bending force of the S1 frame and slightly reducing the intermediate roll bending force, reducing the working roll bending force of the S2 frame and slightly increasing the intermediate roll bending force, increasing the working roll bending force of the S3 frame and increasing the intermediate roll bending force, slightly increasing the working roll bending force of the S4 frame and slightly increasing the intermediate roll bending force, and slightly increasing the working roll bending force of the S5 frame and slightly increasing the intermediate roll bending force.

[0084] Step 3: Divide the solution of the bending roll adjustment effect to solve the parameter problem of adjacent racks into the third effect sub-solution.

[0085] It should be noted that adjacent racks include two adjacent racks or three adjacent racks.

[0086] It should be noted that the solution to the parameter problem of adjacent stands refers to the solution that requires adjusting the similar and unidirectional roll bending forces of adjacent stands. The similar roll bending forces mean that the roll bending forces are all intermediate roll bending forces, or all work roll bending forces, and the unidirectional roll bending forces mean that the roll bending forces all need to be increased by manipulating the operating lever upward, or decreased by manipulating the operating lever downward.

[0087] It should be noted that, according to Table 2, the parameter adjustment scheme obtained from Table 2, and the plate shape adjustment scheme obtained from Table 2, it can be seen that there is no specific scheme in the third effect sub-scheme.

[0088] Step 4: Merge the first effect sub-plan, the second effect sub-plan, and the third effect sub-plan into an effect adjustment plan.

[0089] It should be noted that the effect adjustment scheme includes: the first effect sub-scheme, for which no specific scheme exists. The second effect sub-scheme: reducing the work roll bending force and slightly reducing the intermediate roll bending force of the S1 stand; reducing the work roll bending force and slightly increasing the intermediate roll bending force of the S2 stand; increasing the work roll bending force and increasing the intermediate roll bending force of the S3 stand; slightly increasing the work roll bending force and slightly increasing the intermediate roll bending force of the S4 stand; and slightly increasing the work roll bending force and slightly increasing the intermediate roll bending force of the S5 stand. The third effect sub-scheme: for which no specific scheme exists.

[0090] S205: Selecting an adjustment action for each of the effect adjustment schemes according to the hand operation characteristics to obtain a manual adjustment scheme.

[0091] Referring to Tables 5, 6, and 7, corresponding symbols are selected for different adjustment actions. Assuming that Table 2 shows the interface parameters of the cold rolling mill, an adjustment action is selected for each scheme in the effect adjustment scheme according to the characteristics of hand operation. The method for obtaining the manual adjustment scheme includes the following steps 1 to 5:

[0092] Table 5:

[0093]

[0094] Table 6:

[0095]

[0096] Table 7:

[0097]

[0098] Step 1: Divide the effect adjustment scheme in which the hand operation characteristic is adjusting a bending roller of a frame with one hand into the first manual sub-scheme.

[0099] It should be noted that adjusting a bending roll of a frame with one hand means completing all adjustments of a frame with one hand, and only one bending roll force of the frame needs to be adjusted, and the other bending roll force does not need to be adjusted.

[0100] Referring to Table 5, based on the effect adjustment plan obtained from Table 2, it can be seen that there is no specific plan for the first manual sub-plan.

[0101] Step 2: Divide the effect adjustment scheme whose hand operation characteristic is adjusting the same-direction bending roller with one hand into the second manual sub-scheme.

[0102] It should be noted that single-handed adjustment of the same-direction bending roll means that the working roll bending roll and the intermediate roll bending roll adjusted by one hand belong to the same frame and have the same adjustment direction.

[0103] Referring to Table 6, according to the effect adjustment scheme obtained in Table 2, it can be known that the second manual sub-scheme includes: reducing the working roll bending force of the S1 frame and slightly reducing the intermediate roll bending force by one-hand operation, that is, WR↓, IR slightly↓; increasing the working roll bending force and the intermediate roll bending force of the S3 frame by one-hand operation, that is, WR↑, IR↑; slightly increasing the working roll bending force and the intermediate roll bending force of the S4 frame by one-hand operation, that is, WR slightly↑, IR slightly↑; slightly increasing the intermediate roll bending force and the intermediate roll bending force of the S5 frame by one-hand operation, that is, WR slightly↑, IR slightly↑.

[0104] Step 3: Divide the effect adjustment scheme whose hand operation characteristic is adjusting the cross bending roller with one hand into the third manual sub-scheme.

[0105] It should be noted that single-handed adjustment of the cross bending roll refers to single-handed adjustment of the working roll bending roll and the intermediate roll bending roll of a frame, and the adjustment directions of the two bending rolls are opposite.

[0106] Referring to Table 6, according to the effect adjustment scheme obtained in Table 2, it can be seen that the third manual sub-scheme includes single-handed operation of the S2 frame to reduce the working roll bending force and slightly increase the intermediate roll bending force, that is, WR↓, IR slightly↑.

[0107] Step 4: Divide the effect adjustment scheme whose hand operation characteristic is adjusting the bending rollers of adjacent frames with one hand into the fourth manual sub-scheme.

[0108] It should be noted that adjusting the bending rolls of adjacent frames with one hand refers to adjusting the bending roll forces of the adjacent frames in the same type and direction with one hand.

[0109] Referring to Table 7, based on the effect adjustment scheme obtained from Table 2, it can be seen that there is no specific scheme for the fourth manual sub-scheme.

[0110] Step 5: Combine the first manual sub-plan, the second manual sub-plan, the third manual sub-plan, and the fourth manual sub-plan into a manual adjustment plan.

[0111] It should be noted that the manual adjustment options include: the first manual sub-option, for which no specific solution exists. The second manual sub-option involves single-handedly reducing the bending force of the work rolls and slightly reducing the bending force of the intermediate rolls on the S1 stand (WR↓, IR slightly↓); single-handedly increasing the bending force of the work rolls and the intermediate rolls on the S3 stand (WR↑, IR↑); single-handedly slightly increasing the bending force of the work rolls and the intermediate rolls on the S4 stand (WR slightly↑, IR slightly↑), until the plate shape returns to normal, at which point the bending force remains unchanged; single-handedly increasing the bending force of the intermediate rolls and the intermediate rolls on the S5 stand (WR slightly↑, IR slightly↑), until the plate shape returns to normal, at which point the bending force remains unchanged. The third manual sub-option involves single-handedly reducing the bending force of the work rolls and slightly increasing the bending force of the intermediate rolls on the S2 stand (WR↓, IR slightly↑). The fourth manual sub-option does not have a specific solution.

[0112] It is understandable that after step S205, steps S206 to S207 are further included:

[0113] S206: Based on the manual adjustment solution, the working roll bending and the intermediate roll bending of each frame in the multiple frames are adjusted.

[0114] S207: Obtain a second plate shape judgment result from the monitor; if the second plate shape judgment result shows double-sided waves or middle waves, adjust the plate shape problem based on the second plate shape judgment result; if the second plate shape judgment result is normal, keep the bending roller force unchanged.

[0115] Table 8:

[0116]

[0117] Assuming that Table 8 is the second plate shape judgment result and interface parameters of the cold rolling mill after adjustment by the manual adjustment scheme obtained in Table 2, it can be seen that after adjustment, the working roll bending force of the S1 frame is reduced to the range of 16% to 20%, and the intermediate roll bending force is slightly reduced to the range of -10% to 0%; the working roll bending force of the S2 frame is reduced to the range of 8% to 12%, and the intermediate roll bending force is slightly increased to the range of 0% to 10%; the working roll bending force of the S3 frame is increased to the range of 20% to 24%, and the intermediate roll bending force is increased to the range of -3% to 7%; the working roll bending force of the S4 frame is slightly increased to 15%, and the intermediate roll bending force is slightly increased to 16%. No adjustment is made after the plate shape defects are eliminated; the working roll bending force of the S5 frame is slightly increased to 34%, and the intermediate roll bending force is slightly increased to 43%. No adjustment is made after the plate shape defects are eliminated.

[0118] As shown in Table 8, the second plate shape judgment result shows that both the S1 stand outlet and the S2 stand outlet have double-sided waves. As shown in Tables 3 and 6, based on the second plate shape judgment result, the plate shape problem adjustment includes: slightly increasing the working roll bending force of the S1 stand with one hand, and slightly increasing the intermediate roll bending force, that is, WR slightly ↑, IR slightly ↑; slightly increasing the working roll bending force of the S2 stand with one hand, and slightly increasing the intermediate roll bending force, that is, WR slightly ↑, IR slightly ↑. After continuous adjustment, it was observed that when the working roll bending force of the S1 stand was adjusted to 25% and the intermediate roll bending force was adjusted to 7%, and when the working roll bending force of the S2 stand was adjusted to 14% and the intermediate roll bending force was adjusted to 8%, the wave shape defect was eliminated. At this time, the bending force adjustment was no longer required.

[0119] It should be noted that the above steps S201 to S207 are the complete steps of the manual adjustment method of the bending roll of the cold rolling mill. In order to enhance the understanding of the manual adjustment method of the bending roll of the cold rolling mill, an example is given as follows:

[0120] Example 1: Assume that Table 1 is the interface parameters of the cold rolling mill.

[0121] Step 1: Obtain the first plate shape judgment result of the monitor and obtain interface parameters, as shown in Table 1.

[0122] Step 2: Based on the first plate shape judgment result, obtain the plate shape adjustment plan of the bending roller.

[0123] Since the first flatness judgment result is normal, there is no specific plan for flatness adjustment.

[0124] It should be noted that the adjustment of the bending roll force of the S5 stand is applied in the automatic control of the plate shape. The automatic adjustment mode is selected first. Therefore, when the plate shape at the outlet of the S5 stand is normal, even if the parameter deviation of the working roll bending roll force of the S5 stand is not within the first working roll deviation range, and the parameter deviation of the intermediate roll bending roll force of the S5 stand is not within the first intermediate roll deviation range, the working roll bending roll force and the intermediate roll bending roll force of the S5 stand are not adjusted.

[0125] Step 3: Based on the interface parameters, obtain the parameter adjustment scheme of the bending roll.

[0126] Parameter adjustment options include: No adjustment sub-option: Work roll bending force of S3 stand, intermediate roll bending force of S3 stand, intermediate roll bending force of S4 stand, work roll bending force of S5 stand, and intermediate roll bending force of S5 stand; Fine adjustment sub-option: Work roll bending force of S2 stand, intermediate roll bending force of S1 stand, and intermediate roll bending force of S2 stand; Continuous adjustment sub-option: Work roll bending force of S1 stand, and work roll bending force of S4 stand.

[0127] Step 4: According to the bending roll adjustment effect, the plate shape adjustment plan and the parameter adjustment plan are recombined to obtain the effect adjustment plan.

[0128] The effect adjustment plans include: the first effect sub-plan, which reduces the work roll bending force of the S4 stand. The second effect sub-plan, which reduces the work roll bending force of the S1 stand and slightly reduces the intermediate roll bending force, and slightly reduces the work roll bending force of the S2 stand and slightly increases the intermediate roll bending force. The third effect sub-plan, for which no specific plan is available,

[0129] Step 5: According to the characteristics of hand operation, select an adjustment action for each scheme in the effect adjustment scheme to obtain a manual adjustment scheme.

[0130] Manual adjustment options include: The first manual sub-option involves single-handed operation to reduce the work roll bending force of the S4 stand, with the WR value decreased. The second manual sub-option involves single-handed operation to reduce the work roll bending force of the S1 stand and slightly reduce the intermediate roll bending force, with the WR value decreased and the IR value slightly decreased. The third manual sub-option involves single-handed operation to slightly reduce the work roll bending force of the S2 stand and slightly increase the intermediate roll bending force, with the WR value slightly decreased and the IR value slightly increased. A fourth manual sub-option exists: no specific solution exists for this fourth manual sub-option.

[0131] The above manual adjustment scheme was implemented, and the plate shape judgment results and interface parameters on the monitor were observed and fed back. No plate shape problems occurred, the adjustment was effective, and the bending roll force remained unchanged.

[0132] Example 2: Assume that Table 4 is the interface parameters of the cold rolling mill.

[0133] Step 1: Obtain the first plate shape judgment result of the monitor and obtain interface parameters, as shown in Table 4.

[0134] Step 2: Based on the first plate shape judgment result, obtain the plate shape adjustment plan of the bending roller.

[0135] The plate shape adjustment plan includes: slightly reducing the bending force of the working roll of the S1 frame and slightly reducing the bending force of the intermediate roll. After eliminating the plate shape defects, the bending force adjustment of the S1 frame will no longer be considered in the subsequent parameter adjustment plan.

[0136] Step 3: Based on the interface parameters, obtain the parameter adjustment scheme of the bending roll.

[0137] Parameter adjustment options include: a no-adjustment sub-option for the intermediate roll bending force of stand S3, stand S4, and stand S5, as well as the work and intermediate roll bending forces of stand S1 after the plate shape returns to normal; a fine-tuning sub-option for the work roll bending force of stand S3, stand S4, and stand S2, and a continuous adjustment sub-option for the work roll bending force of stand S2.

[0138] Step 4: According to the bending roll adjustment effect, the plate shape adjustment plan and the parameter adjustment plan are recombined to obtain the effect adjustment plan.

[0139] The effect adjustment scheme includes: the first effect sub-scheme, which has no specific plan. The second effect sub-scheme is to slightly reduce the bending force of the work rolls and the intermediate rolls of the S1 stand, and slightly reduce the bending force of the work rolls and the intermediate rolls of the S2 stand. The third effect sub-scheme is to slightly reduce the bending force of the work rolls of the S3 and S4 stands.

[0140] Step 5: According to the characteristics of hand operation, select an adjustment action for each scheme in the effect adjustment scheme to obtain a manual adjustment scheme.

[0141] Manual adjustment options include: the first manual sub-option, for which no specific solution is available. The second manual sub-option involves single-handedly reducing the bending force of the work rolls and the intermediate rolls on stand S1, slightly decreasing the WR and IR until the plate shape returns to normal, at which point the bending force remains unchanged. The third manual sub-option involves single-handedly reducing the bending force of the work rolls and the intermediate rolls on stand S2, slightly decreasing the WR and IR. There is no specific solution for the third manual sub-option. The fourth manual sub-option involves single-handedly reducing the bending force of the work rolls on stands S3 and S4, slightly decreasing the WR and IR.

[0142] The above manual adjustment scheme was implemented, and the plate shape judgment results and interface parameters on the monitor were observed and fed back. No plate shape problems occurred, the adjustment was effective, and the bending roll force remained unchanged.

[0143] The embodiment of the present invention obtains the interface parameters by obtaining the first plate shape judgment result from the monitor; obtains the plate shape adjustment plan of the bending roll based on the first plate shape judgment result; obtains the parameter adjustment plan of the bending roll based on the interface parameters; recombines the plate shape adjustment plan and the parameter adjustment plan according to the bending roll adjustment effect to obtain the effect adjustment plan; selects an adjustment action for each plan in the effect adjustment plan according to the hand operation characteristics to obtain a manual adjustment plan. Through the accumulation of actual production operating experience, combined with the bending roll adjustment effect and the hand operation characteristics, a classification and summary are made to summarize the manual adjustment direction of the bending roll adjustment, ultimately solving the plate shape problem and the bending roll force parameter problem, thereby solving the technical problem of enhancing the purposefulness of manual adjustment.

[0144] Based on the same invention concept, Figure 5 As shown, an embodiment of the present invention provides a manual adjustment device 10 for the bending roll of a cold rolling mill.

[0149] It can be understood that the first scheme generating unit 120 is specifically used to: if the first plate shape judgment result is that the plate shape of the frame is double-sided wave, increase the bending force of the working roll bending roll and the intermediate roll bending roll of the frame; if the first plate shape judgment result is that the plate shape of the frame is medium wave, reduce the bending force of the working roll bending roll and the intermediate roll bending roll of the frame.
