Description

TECHNICAL FIELD

[0001] The present application relates to the field of strip steel smelting, and in particular to a strip steel control method, device and equipment. BACKGROUND

[0002] In the production process of strip steel, the strip steel needs to go through cold rolling and continuous annealing and other processing steps to achieve the purposes of eliminating stress of the strip steel, reducing carbon content of the strip steel and coating the strip steel.

[0003] Before the strip steel is cold-rolled, a deviation rectifying device rectifies the strip steel, but at the same time, the strip steel is subjected to uneven stress, which causes the strip steel to be warped. After the strip steel subjected to uneven stress enters a cleaning system, the strip steel is prone to deviation due to the complexity of the cleaning system. After the strip steel deviates, the warped part of the strip steel is crushed by a squeezing roller and a brush roller, and the strip steel is prone to folding or breaking. The folding or breaking of the strip steel seriously affects the stable operation of a production unit. Therefore, how to effectively reduce the probability of folding or breaking of the strip steel after the strip steel deviates in the cleaning system is a problem to be solved. SUMMARY

[0037] The present application acquires the actual thickness of the strip steel, and monitors the actual offset of the strip steel in the cleaning system in real time. For the relatively thin strip steel, if the actual offset is greater than or equal to the first preset offset and less than the second preset offset, the cleaning system is controlled to open the squeeze roll and the brush roll, and the unit is controlled to reduce to the first preset running speed. By controlling the cleaning system to open the squeeze roll and the brush roll, and controlling the unit to reduce to the first preset running speed, the stress received by the relatively thin strip steel can be effectively reduced. As the stress received by the strip steel is reduced, the stress received by the buckling part of the strip steel is also reduced, thereby reducing the probability of wrinkles or strip breakage of the strip steel.

[0038] The present application also adopts different processing methods for different thicknesses of the strip steel. For the relatively "thin" strip steel, if the actual offset is greater than or equal to the second preset offset, the control system stops the operation of the unit and sends an audible and light alarm signal after opening the squeeze roll and the brush roll of the cleaning system, which can effectively reduce the probability of strip breakage of the relatively "thin" strip steel. For the relatively "thick" strip steel, if the actual offset is greater than the first preset offset and less than the second preset offset, the control system reduces the speed of the unit to the second preset running speed, which can effectively reduce the probability of folding or strip breakage of the relatively "thick" strip steel; if the actual offset is greater than or equal to the second preset offset and less than the third preset offset, the control system opens the squeeze roll and the brush roll of the cleaning system and reduces the speed of the unit to the first preset running speed, which can further reduce the probability of folding or strip breakage of the relatively "thick" strip steel; if the actual offset is greater than or equal to the third preset offset, the control system stops the operation of the unit and sends an audible and light alarm signal after opening the squeeze roll and the brush roll of the cleaning system, which can effectively reduce the probability of strip breakage of the relatively "thick" strip steel. The present application adopts different processing methods for different thicknesses of the strip steel, which can accurately process the strip steel of different thicknesses and improve the processing efficiency.

[0039] After the unit stops running, the present application determines the target opening to reduce the time required for processing the maximum deformation of the strip steel, and by cutting and welding the maximum deformation, the most likely strip breakage of the strip steel can be processed, thereby reducing the probability of strip breakage of the strip steel. After the unit stops running, the present application detects whether each roll body in the cleaning system is damaged, and if damaged, it is replaced to avoid the damaged roll body affecting the cleaning effect of the strip steel.

[0050] The embodiment of the present application provides a strip steel control method, and solves the technical problem that the strip steel is prone to folding or breaking in the cleaning system in the prior art.

[0051] The technical scheme of the embodiment of the present application is as follows to solve the above technical problem:

[0052] A strip steel control method, the method comprising: acquiring an actual thickness of the strip steel; monitoring an actual offset amount of the strip steel in a cleaning system in real time; if the actual offset amount is greater than or equal to a first preset offset amount and less than a second preset offset amount, and the actual thickness is less than or equal to a preset thickness threshold, controlling the cleaning system to open a squeezing roller and a brush roller, and controlling a unit to reduce speed to a first preset running speed, the unit comprising the cleaning system and a furnace control system.

[0053] The present application acquires the actual thickness of the strip steel, and monitors the actual offset amount of the strip steel in the cleaning system in real time, and for the relatively thin strip steel, if the actual offset amount is greater than or equal to the first preset offset amount and less than the second preset offset amount, the cleaning system is controlled to open the squeezing roller and the brush roller, and the unit is controlled to reduce speed to the first preset running speed. By controlling the cleaning system to open the squeezing roller and the brush roller, and controlling the unit to reduce speed to the first preset running speed, the stress received by the relatively thin strip steel can be effectively reduced, the stress received by the strip steel is reduced, and the stress received by the buckling part of the strip steel is also reduced, so that the probability of folding or breaking of the strip steel is reduced.

[0054] The present application also adopts different processing methods for different thicknesses of the strip steel. For the relatively "thin" strip steel, if the actual offset is greater than or equal to the second preset offset, the control system stops running and sends an audible and light alarm signal after the squeezing roller and the brush roller of the cleaning system are opened, which can effectively reduce the probability of strip breakage of the relatively "thin" strip steel. For the relatively "thick" strip steel, if the actual offset is greater than the first preset offset and less than the second preset offset, the control system is controlled to reduce the speed to the second preset running speed, which can effectively reduce the probability of folding or strip breakage of the relatively "thick" strip steel; if the actual offset is greater than or equal to the second preset offset and less than the third preset offset, the control system is controlled to open the squeezing roller and the brush roller of the cleaning system and reduce the speed to the first preset running speed, which can further reduce the probability of folding or strip breakage of the relatively "thick" strip steel; if the actual offset is greater than or equal to the third preset offset, the control system stops running and sends an audible and light alarm signal after the squeezing roller and the brush roller of the cleaning system are opened, which can effectively reduce the probability of strip breakage of the relatively "thick" strip steel. The present application adopts different processing methods for different thicknesses of the strip steel, which can more accurately process strip steels of different thicknesses and improve the processing efficiency.

[0055] After the control system stops running, the present application determines the target opening to reduce the time required for processing the maximum deformation of the strip steel, and the strip steel is processed at the most likely position of strip breakage by cutting and welding, thereby reducing the probability of strip breakage. After the control system stops running, the present application detects whether each roller body in the cleaning system is damaged, and replaces the damaged roller body to avoid affecting the cleaning effect of the strip steel.

[0056] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings and specific embodiments of the specification.

[0057] First of all, the term "and / or" appearing in this paper is only to describe the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can represent the existence of A alone, the existence of A and B together, and the existence of B alone. In addition, the character " / " in this paper generally represents an "or" relationship between the front and rear associated objects.

[0058] The present application provides a strip steel control method as shown in Figure 1 The method comprises steps S11-S13:

[0059] Step S11, obtaining the actual thickness of the strip steel.

[0060] Step S12, real-time monitoring the actual offset of the strip steel in the cleaning system.

[0061] If the actual offset is greater than or equal to the first preset offset and less than the second preset offset, and the actual thickness is less than or equal to the preset thickness threshold, the control system opens the squeeze roll and the brush roll of the cleaning system, and controls the unit to reduce the speed to the first preset running speed, the unit including the cleaning system and the furnace control system.

[0062] The present application provides a strip steel control method as shown in Figure 1 The strip steel process section unit as shown in Figure 2 The strip steel process section unit as shown in Figure 2 is a schematic diagram of the equipment distribution of the process section unit, Figure 3 is a schematic diagram of the cleaning system 2. Figure 2 is a partial enlarged schematic diagram of the cleaning system 2.

[0063] The strip steel process section unit as shown in Figure 2 may include a deviation rectifying device 1, a cleaning system 2, a furnace control system 3, a backing plate 4, and a controller (not shown in the figure). Figure 3 The cleaning system 2 as shown in may include the backing plate 4, a brush roll 5, and a squeeze roll 6.

[0064] The strip steel can be high-grade non-oriented silicon steel, or other types of silicon steel, which is not limited here.

[0065] As shown in Figure 2 , the strip steel 7 is rectified by the deviation rectifying device 1 and then enters the cleaning system 2 for cleaning. The strip steel 7 passes through the brush roll 5 and the squeeze roll 6 in the cleaning system 2 in sequence, achieving the purpose of cleaning the surface of the strip steel and squeezing the surface moisture of the strip steel (there can be multiple brush rolls 5 and multiple sets of squeeze rolls 6 in the cleaning system 2, Figure 2 only one brush roll 5 and one set of squeeze rolls 6 are shown in the figure). After passing through the cleaning system 2, the strip steel enters the furnace control system 3 for continuous annealing treatment, achieving the purpose of reducing the carbon content of the strip steel.

[0066] It should be noted that the strip steel may have deviated before entering the cleaning system 2, i.e., the center line of the strip steel does not coincide with the center line of the backing plate 4 (the backing plate 4 is used to support the strip steel), i.e., the strip steel has deviated. For example, Figure 4 , the center line L of the strip steel 7 (only part of the strip steel is shown here) does not coincide with the center line O of the backing plate 4, which means that the strip steel 7 has deviated. The deviation of the strip steel 7 can be rectified by the deviation rectifying device 1, so that the center line of the strip steel 7 coincides with the center line of the backing plate 4.

[0067] It should also be noted that, to ensure the continuity of strip steel production 7, the cleaning system 2 and the furnace control system 3 must operate at the same speed (i.e., the liner 4 in the cleaning system 2, the liner 4 in the furnace control system 3, and the strip steel 7 must advance at the same speed). If the cleaning system 2 and the furnace control system 3 do not operate at the same speed, the strip steel will wrinkle or break. The controller is used to... Figure 1 The method shown is used to control the strip steel processing unit. Please refer to the following instructions for details:

[0068] Regarding step S11, obtain the actual thickness of the strip.

[0069] Generally speaking, the actual thickness of strip steel in the same batch is the same. The actual thickness of strip steel can be obtained by ultrasonic method, X-ray method or other methods, and there is no restriction here.

[0070] Furthermore, the thicker the actual thickness of the strip, the stronger its resistance to wrinkling or breakage; the thinner the strip, the weaker its resistance to wrinkling or breakage.

[0071] Regarding step S12, the actual offset of the strip in the cleaning system is monitored in real time.

[0072] like Figure 2 As shown, after being corrected by the straightening device 1, the strip 7 can enter the cleaning system 2. After the strip 7 enters the cleaning system 2, the actual offset of the strip 7 in the cleaning system can be monitored in real time. A fixed point can be selected in the cleaning system, and the straight line perpendicular to the center line of the liner 4 is taken as the target line. The portion of the target line intercepted by the center line of the strip 7 and the center line of the liner 4 is the actual offset of the strip (or the angle between the center line of the strip 7 and the center line of the liner 4 can be used as the actual offset; in the following description, "distance" will be used as the actual offset of the strip). For example, in... Figure 4 In the middle, the fixed point is Q, and the part of the straight line containing point Q and perpendicular to the center line L of the liner 4 that is intercepted by the straight line L and the straight line O is P, that is, the offset of the strip 7 is P.

[0073] It should be noted that, Figure 5 This is a side view of the liner 4 in the cleaning system 2. Because the liner 4 in the cleaning system 2 is "S" shaped, the strip 7 moves in an "S" shaped manner in the cleaning system 2.

[0074] Furthermore, because the strip moves in an "S" shape in the cleaning system, the greater the offset of the strip in the cleaning system, the more concentrated the stress is on the curved parts of the strip (the curved parts of the strip refer to the gourd-shaped defects formed on both sides of the strip due to uneven stress on both sides) compared to other parts of the strip. The probability of wrinkles or breakage in the curved parts of the strip will be greater.

[0075] If the actual offset is greater than or equal to the first preset offset and less than the second preset offset, and the actual thickness is less than or equal to the preset thickness threshold, the control system controls the cleaning system to open the squeeze roll and the brush roll, and controls the unit to reduce the speed to the first preset running speed, the unit including the cleaning system and the furnace control system.

[0076] The thicker the actual thickness of the strip steel, the stronger the anti-wrinkling or anti-broken strip capability of the strip steel; the thinner the thickness of the strip steel, the weaker the anti-wrinkling or anti-broken strip capability of the strip steel. Therefore, the way to reduce the probability of the wrinkling or broken strip at the curling position of the strip steel can be different according to the different thicknesses of the strip steel. Different processing methods can be taken for strip steels with different thicknesses according to the relationship between the thickness of the strip steel and the preset thickness threshold, as follows:

[0077] For simplicity, the processing method corresponding to the actual thickness of the strip steel being less than or equal to the preset thickness threshold is denoted as

Method 1

Method 2

[0078]

Method 1

[0079] When the actual thickness of the strip steel is less than or equal to the preset thickness threshold, it means that the anti-wrinkling or anti-broken strip capability of the strip steel is weak. For the strip steel with weak anti-wrinkling or anti-broken strip capability, different methods can be taken to reduce the probability of the wrinkling or broken strip at the curling position of the strip steel according to the actual offset of the strip steel, which can be divided into {Method A} and {Method B}.

[0080] {Method A}

[0081] If the actual offset is greater than or equal to the first preset offset and less than the second preset offset, and the actual thickness is less than or equal to the preset thickness threshold, the control system controls the cleaning system to open the squeeze roll and the brush roll, and controls the unit to reduce the speed to the first preset running speed, the unit including the cleaning system and the furnace control system.

[0082] The first preset offset can be set to 40 mm, 50 mm, 60 mm, etc., which can be selected according to actual conditions, and is not limited here. For example, the inventors found through many experiments that a certain high-grade non-oriented silicon steel has a probability of broken strip in the cleaning system when the offset is greater than 60 mm. At this time, the first preset offset can be set to 60 mm, 59 mm, or 58 mm, etc.

[0083] The second preset offset is greater than the first preset offset. For example, when the first preset offset is 60 mm, the second preset offset can be set to 70 mm, 75 mm, 81 mm, etc. The specific value can be determined according to actual conditions.

[0084] The preset thickness threshold can be set to 0.3 mm, 0.35 mm, or 0.5 mm, etc. The specific value can be selected according to actual conditions.

[0085] When the actual thickness of the strip steel is less than or equal to the preset thickness threshold, the anti-wrinkling ability or the anti-broken strip ability of the strip steel is weak. If the actual offset of the strip steel in the cleaning system is greater than the first preset offset and less than the second preset offset, it indicates that the anti-wrinkling ability or the anti-broken strip ability of the strip steel can be insufficient to "resist" the wrinkling part of the strip steel from wrinkling or breaking. By controlling the cleaning system to open the squeeze roll and the brush roll, and controlling the unit to reduce the speed to the first preset running speed, the probability of the wrinkling part of the strip steel from wrinkling or breaking can be reduced.

[0086] The squeeze roll in the cleaning system squeezes the moisture on the surface of the strip steel by squeezing, and the brush roll cleans the impurities on the surface of the strip steel by washing. Both "squeezing" and "washing" will cause the stress of the wrinkled part of the strip steel to be more concentrated, and the wrinkled part is more likely to wrinkle or break. Therefore, by controlling the cleaning system to open the squeeze roll and the brush roll, the probability of the wrinkled part of the strip steel from wrinkling or breaking can be effectively reduced.

[0087] Generally, when the unit produces strip steel, the running speed of the unit is a fixed speed. For example, when producing a certain high-grade non-oriented silicon steel, the running speed of the unit is 2 m / s. The first preset running speed can be set to 0.3 m / s, 0.35 m / s, or 0.41 m / s of the unit. The specific value can be determined according to actual conditions.

[0088] Controlling the unit to reduce the speed to the first preset running speed, in other words, reducing the running speed of the unit, that is, reducing the running speed of the cleaning system and the furnace control system. The running speed of the unit is reduced, and the stress on the inside of the strip steel is also reduced. The lower the stress on the inside of the strip steel, the lower the stress on the wrinkled part of the strip steel, and the smaller the probability of the wrinkled part of the strip steel from wrinkling or breaking. Therefore, reducing the running speed of the cleaning system and the furnace control system can effectively reduce the probability of the wrinkled part of the strip steel from wrinkling or breaking.

[0089] For example, the inventors found through long-term experiments that when the preset thickness threshold is 0.3 mm, the first preset offset is 60 mm, and the second preset offset is 80 mm, the first preset running speed of the unit can be set to 0.4 m / s; when the actual offset of the 0.25 mm strip steel is greater than 60 mm and less than 80 mm, controlling the unit to slow down to 0.4 m / s can effectively reduce the probability of wrinkles or broken strips at the buckling part of the strip steel.

[0090] In summary, by controlling the cleaning system to open the squeeze dry roller and the brush roller, the stress on the buckling part of the strip steel can be effectively reduced, and controlling the unit to slow down to the first preset running speed can further reduce the stress on the buckling part of the strip steel. In other words, the probability of wrinkles or broken strips at the buckling part of the strip steel is also reduced.

[0091] {Method B}

[0092] If the actual offset is greater than or equal to the second preset offset, and the actual thickness is less than or equal to the preset thickness threshold, then after the cleaning system opens the squeeze dry roller and the brush roller, the unit is controlled to stop running and an audible and visual alarm signal is issued.

[0093] In the strip steel after the cleaning system, if the actual offset of the strip steel is greater than or equal to the second preset offset, it means that the offset of the strip steel is large at this time, and the stress on the buckling part is more concentrated; and because the strip steel is thin, the anti-wrinkle ability or anti-broken strip ability of the strip steel is weak, which means that the strip steel is likely to break.

[0094] By controlling the cleaning system to open the squeeze dry roller and the brush roller, the stress on the strip steel can be reduced, and the probability of broken strips can be reduced; after the cleaning system opens the squeeze dry roller and the brush roller, the unit is controlled to stop running to avoid broken strips and an audible and visual alarm signal is issued to remind relevant personnel to check.

[0095] It should be noted that controlling the unit to stop running takes a certain amount of time, so in order to reduce the probability of broken strips, the cleaning system needs to be controlled to open the squeeze dry roller and the brush roller first.

[0096]

Method 2

[0097] When the actual thickness of the strip steel is greater than the preset thickness threshold, it means that the anti-wrinkle ability or anti-broken strip ability of the strip steel is strong. For strip steel with strong anti-wrinkle ability or anti-broken strip ability, different methods can be used to reduce the probability of wrinkles or broken strips at the buckling part of the strip steel according to the actual offset of the strip steel. Specifically, it can be divided into {Method C}, {Method D}, and {Method E}.

[0098] {Method C}

[0099] If the actual offset is greater than or equal to the first preset offset and less than the second preset offset, and the actual thickness is greater than the preset thickness threshold, the machine set is controlled to reduce speed to a second preset operating speed, and the second preset operating speed is greater than the first preset operating speed.

[0100] The second preset operating speed is greater than the first preset operating speed, for example, when the first preset operating speed is 0.3 m / s, the second preset operating speed can be 0.5 m / s, 0.6 m / s or 0.65 m / s, which can be determined according to actual conditions.

[0101] When the actual thickness of the strip steel is greater than the preset thickness threshold, the anti-wrinkling or anti-broken strip capability of the strip steel is stronger. If the actual offset of the strip steel is greater than the first preset offset and less than the second preset offset, it means that the strip steel has a certain degree of offset at this time, but the anti-wrinkling or anti-broken strip capability of the relatively "thick" strip steel can resist the wrinkling or broken strip of the strip steel to a certain extent, and the probability of the wrinkling or broken strip of the curved part of the strip steel can be reduced or avoided by only reducing the operating speed of the machine set.

[0102] {Method D}

[0103] If the actual offset is greater than or equal to the second preset offset and less than the third preset offset, and the actual thickness is greater than the preset thickness threshold, the squeeze roll and the brush roll of the cleaning system are controlled to be opened, and the machine set is controlled to reduce speed to the first preset operating speed.

[0104] The third preset offset is greater than the second preset offset, for example, when the second preset offset is 80 mm, the third preset offset can be set to 85 mm, 90 mm or 91 mm, etc., which can be determined according to actual conditions.

[0105] When the actual offset of the strip steel is greater than the second preset offset and less than the third preset offset, the probability of the wrinkling or broken strip of the strip steel is greater than when the actual offset is greater than or equal to the first preset offset and less than the second preset offset, the probability of the wrinkling or broken strip of the strip steel can be reduced by controlling the cleaning system to open the squeeze roll and the brush roll, and the operating speed of the machine set can be further reduced by controlling the machine set to reduce speed to the first preset operating speed, and the probability of the wrinkling or broken strip of the strip steel can be further reduced by controlling the machine set to reduce speed to the first preset operating speed.

[0106] {Method E}

[0107] If the actual offset is greater than or equal to the third preset offset and the actual thickness is greater than the preset thickness threshold, the machine set is controlled to stop running and an audible and visual alarm signal is sent after the squeeze roll and the brush roll of the cleaning system are controlled to be opened.

[0108] When the actual offset of the strip steel is greater than or equal to the third preset offset, it indicates that the stress of the buckling part of the strip steel is large at this time, although the strip steel has a certain anti-wrinkling ability or anti-broken strip ability, but it is not enough to "resist" the strip steel from wrinkling or breaking. Therefore, it is necessary to control the cleaning system to open the squeeze roller and the brush roller to reduce the probability of strip steel breaking, after the cleaning system opens the squeeze roller and the brush roller, the unit is controlled to stop running to avoid the strip steel from breaking, and an audible and visual alarm signal is sent to remind the relevant staff to check.

[0109] Further, after adopting the {method B} or the {method E}, the strip steel and the roller body can also be treated, specifically as follows:

[0110] {Treatment of the strip steel}

[0111] The first distance between the maximum deformation part of the strip steel in the cleaning system and the outlet of the cleaning system and the second distance between the maximum deformation part and the inlet of the cleaning system are determined, the target port is determined from the outlet and the inlet according to the smaller value of the first distance and the second distance, the maximum deformation part of the strip steel is pulled to the target port, and after the maximum deformation part is cut at the target port, the strip steel is welded.

[0112] When the offset of the "thinner" strip steel is greater than or equal to the second preset offset and the offset of the "thicker" strip steel is greater than or equal to the third preset offset, it indicates that the probability of strip steel breaking at this time is large, so the unit needs to be controlled to stop running and the relevant personnel are notified to check.

[0113] After the unit stops running, the maximum deformation part of the strip steel in the cleaning system is obtained, which means the part of the strip steel that is most prone to breaking, the first distance between the maximum deformation part and the inlet of the cleaning system and the second distance between the maximum deformation part and the outlet of the cleaning system are determined, and the target port is determined from the outlet and the inlet according to the smaller value of the first distance and the second distance. The target port is closer to the maximum deformation part, so when the maximum deformation part is pulled to the target port, the time used is also less, which improves the processing efficiency.

[0114] After the maximum deformation part of the strip steel is pulled to the target port and cut, the strip steel is welded. By cutting the maximum deformation part, the part of the strip steel that is most prone to breaking is cut, in other words, the probability of strip steel breaking is reduced. After the strip steel is welded, the unit can continue to run.

[0115] {Treatment of the roller body}

[0116] Further, after the unit stops running, it is detected whether each roller body in the cleaning system is damaged, and if there is a damaged roller body, the damaged roller body is replaced with a same type of undamaged roller body.

[0117] When the unit stops running, in order to avoid the bending part of the strip steel (the bending part of the strip steel is relatively sharp) cutting the various roller bodies in the cleaning system, it can be detected whether the various roller bodies in the cleaning system are damaged; if the roller body is damaged, the damaged roller body needs to be replaced with a non-damaged roller body of the same type.

[0118] In summary, the actual thickness of the strip steel is obtained, and the actual offset of the strip steel in the cleaning system is monitored in real time. For relatively "thin" strip steel, if the actual offset is greater than or equal to the first preset offset and less than the second preset offset, the cleaning system is controlled to open the squeeze dry roller and the brush roller, and the unit is controlled to reduce the speed to the first preset running speed. By controlling the cleaning system to open the squeeze dry roller and the brush roller, and controlling the unit to reduce the speed to the first preset running speed, the stress on the inside of the relatively "thin" strip steel can be effectively reduced, and the stress on the inside of the strip steel is reduced. The stress on the bending part of the strip steel is also reduced, thereby reducing the probability of wrinkles or strip breakage of the strip steel.

[0119] The present application also adopts different processing methods for strip steels of different thicknesses. For relatively "thin" strip steel, if the actual offset is greater than or equal to the second preset offset, the cleaning system is controlled to open the squeeze dry roller and the brush roller, and the unit is controlled to stop running and issue an audible and light alarm signal, which can effectively reduce the probability of strip breakage of the relatively "thin" strip steel. For relatively "thick" strip steel, if the actual offset is greater than the first preset offset and less than the second preset offset, the unit is controlled to reduce the speed to the second preset running speed, which can effectively reduce the probability of wrinkles or strip breakage of the relatively "thick" strip steel; if the actual offset is greater than or equal to the second preset offset and less than the third preset offset, the cleaning system is controlled to open the squeeze dry roller and the brush roller, and the unit is controlled to reduce the speed to the first preset running speed, which can further reduce the probability of wrinkles or strip breakage of the relatively "thick" strip steel; if the actual offset is greater than or equal to the third preset offset, the cleaning system is controlled to open the squeeze dry roller and the brush roller, and the unit is controlled to stop running and issue an audible and light alarm signal, which can effectively reduce the probability of strip breakage of the relatively "thick" strip steel. The present application adopts different processing methods for strip steels of different thicknesses, which can more accurately process strip steels of different thicknesses, thereby improving the processing efficiency.

[0120] After the unit stops running, the target opening is determined to reduce the time required to process the maximum deformation of the strip steel. By trimming and welding the maximum deformation, the most likely strip breakage of the strip steel can be processed, thereby reducing the probability of strip breakage of the strip steel. After the unit stops running, the present application detects whether the various roller bodies in the cleaning system are damaged, and replaces the damaged roller body if it is damaged, which can avoid the effect of the damaged roller body on cleaning the strip steel.
