Description

Technical Field

[0001] The present invention belongs to the field of smelting technology, and in particular relates to a method, device and equipment for detecting grinding marks of a rolling mill roll. Background Art

[0002] The working rolls used in the cold rolling mill to produce automobile outer panels have very high surface quality requirements. Visually visible defects such as chatter marks, horizontal lines, burns, scratches, and grinding marks are not allowed on the surface. In particular, grinding marks on spiral rolls are not allowed to exist, even if they can only be found after grinding with an oilstone. Once missed, the production line will be shut down for roll replacement and waste will be generated. Grinding the roll surface after roller grinding is a destructive test. Even if no grinding marks are found, the roll cannot be used. However, existing grinding mark detection methods are too simple, resulting in low grinding efficiency when the grinding mark detection rate is high, or low grinding mark detection rate when the grinding efficiency is high. Therefore, balancing the grinding mark detection rate and grinding efficiency is a technical problem that needs to be solved urgently. Summary of the Invention

[0022] 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.

[0023] 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 combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0024] The embodiment of the present invention provides a method for detecting grinding marks of a roller, referring to Figure 1 As shown, the method includes the following steps:

[0025] S101: Perform a full-body inspection on the first roller to improve the detection rate of grinding marks.

[0026] It should be noted that the number of rollers in the first roller is 1. The first roller can be the first roller to be ground, the current roller with grinding marks among the second rollers, and the next roller to be ground corresponding to the roller when the number of no marks is equal to the first number threshold.

[0027] It should be noted that the first roll in a group of rolls to be ground refers to the roll that is ground first in a group of rolls to be ground. The purpose of performing full-body inspection and end inspection on the first roll in a group of rolls to be ground is to improve the detection rate of grinding marks, and to adjust the grinding process when grinding marks exist so that the grinding process meets the requirements.

[0028] It should be noted that the whole body inspection and end inspection are performed on the next roller to be ground corresponding to the roller when the number of mark-free times is equal to the first number threshold. This is because when it is determined that there are no grinding marks on the roller for multiple consecutive times and end inspection is mainly used, the grinding efficiency is improved, but the grinding mark detection rate is reduced. This method is adopted to balance the grinding efficiency and the grinding mark detection rate.

[0029] It is understandable that the method for performing a full-body inspection on the first roller includes the following steps S1011 to S1013:

[0030] S1011: Grinding the first roller.

[0031] S1012: Grinding the entire first roller.

[0032] refer to Figure 2 As shown, use an oilstone to grind the roll surface along the roll axis from one end to the other. The oilstone is applied in the axial direction of the roll. The circumferential grinding area of ​​the roll is greater than 50 mm, specifically 51 mm. When grinding the roll surface, the oilstone must be placed flat and the force applied moderately. The oilstone can be a 320-mesh oilstone. The work roll surface length can be 2000 mm, and the maximum width of the cold-rolled strip produced can be 1800 mm.

[0033] S1013: Determine whether there is a first grinding mark on the first roller.

[0034] It is understandable that the method for determining whether the first grinding mark exists on the first roller includes the following steps 1 and 2:

[0035] Step 1: If there is a first grinding mark on the first roller, adjust the grinding process and re-execute the step of performing a full-body inspection on the first roller.

[0036] Specifically, if spiral lines are visible during grinding, the roller is reground by adjusting the grinding process until the grinding inspection lines disappear, and the roller is reground according to the last grinding process.

[0037] Step 2: If there is no first grinding mark on the first roller, the first roller is determined to be qualified.

[0038] S102: Perform end detection on the second roller to improve grinding efficiency.

[0039] It should be noted that the number of rollers in the second roller is 4 to 8.

[0040] It is understandable that the method for detecting the end of the second roller includes the following steps S1021 to S1024:

[0041] S1021: Grinding the second roller.

[0042] S1022: Grinding the end of the second roller.

[0043] refer to Figure 3 As shown, the end grinding direction is along the roll axial direction. The axial grinding range is from 10mm outside the rolling line of the widest steel strip rolled by the roll to the roll end. The circumferential grinding area of ​​the roll is greater than 50mm along the circumference of the roll, specifically 51mm. The axial grinding range from the roll end to the roll body side can be 90mm, the work roll surface length can be 2000mm, and the maximum width of the cold-rolled strip produced can be 1800mm.

[0044] S1023: If there are grinding marks on the second roller, the current roller with the grinding marks among the second rollers is used as the first roller, and a step of performing a full-body inspection on the first roller is performed.

[0045] It should be noted that the current roller with grinding marks in the second roller is used as the first roller, and the step of performing a full-body inspection on the first roller is to adjust the grinding process and improve the grinding mark detection rate.

[0046] S1024: If there is no grinding mark on the second roller, the second roller is determined to be qualified.

[0047] S103: Record the number of rollers among the first roller and the second roller that are continuously determined to have no grinding marks as the number of no-mark times.

[0048] It can be understood that in response to the number of traceless times being equal to the first threshold value, the number of traceless times is cleared to zero.

[0049] It should be noted that, since the roller is judged to have no grinding marks for many consecutive times and end detection is mainly used, the grinding efficiency is improved, but the grinding mark detection rate is reduced. In order to achieve the purpose of balancing the grinding efficiency and the grinding mark detection rate, the number of no marks is recorded to determine the timing of full-body inspection and end inspection.

[0050] This embodiment of the present invention performs a full-body inspection on the first roller to improve the grinding mark detection rate; performs an end inspection on the second roller to improve grinding efficiency; and records the number of the first and second rollers that are consecutively determined to be free of grinding marks as the number of no-mark tests. By grouping the rollers and testing different parameters, both the grinding mark detection rate and grinding efficiency are balanced. Thus, a balance between the grinding mark detection rate and grinding efficiency is achieved, at least to a certain extent.

[0051] Based on the same invention concept, Figure 4 As shown, an embodiment of the present invention provides a grinding mark detection device 10 for a rolling mill, comprising: a first detection unit 110, for performing a full-body detection on the first rolling mill to improve the detection rate of grinding marks; a second detection unit 120, for performing an end detection on the second rolling mill to improve the grinding efficiency; and a recording unit 130, for recording the number of rolling mills in the first rolling mill and the second rolling mill that are continuously determined to have no grinding marks, as the number of no-mark times.

[0052] It can be understood that the first detection unit 110 includes: a first grinding subunit 1110 for grinding the first roller; a full-body grinding subunit 1120 for full-body grinding the first roller; and a first judgment subunit 1130 for judging whether there is a first grinding mark on the first roller.

[0053] It is understood that the first determination subunit 1130 is specifically configured to: if the first roller has the first grinding mark, adjust the grinding process and re-perform the step of performing a full-body inspection on the first roller; and if the first roller does not have the first grinding mark, determine that the first roller is qualified.

[0054] It is understandable that the second detection unit 120 includes:

[0055] The second grinding subunit 1210 is used for grinding the second roller;

[0056] An end grinding subunit 1220 is used to grind the end of the second roller;

[0057] The second judgment subunit 1230 is used to, if there are grinding marks on the second roller, use the current roller with grinding marks in the second roller as the first roller and perform the step of performing a full-body inspection on the first roller; if there are no grinding marks on the second roller, determine that the second roller is qualified.

[0058] It should be noted that the first roller includes: the first roller among the rollers to be ground, the current roller with grinding marks among the second rollers, and the next roller to be ground corresponding to the roller when the number of mark-free times is equal to the first number threshold.

[0059] The roller grinding mark detection device 10 further includes: a response unit 140, configured to clear the number of no-mark times to zero in response to the number of no-mark times being equal to a first threshold value.

[0060] It should be noted that the number of rollers in the first roller is 1; the number of rollers in the second roller is 4 to 8.

[0061] It should be understood that more implementation details of the roller grinding mark detection device 10 in the embodiment of the present invention can be found in the aforementioned roller grinding mark detection method, and will not be repeated here for the sake of brevity.

Bus 500 may also link various other circuits such as peripherals, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. Bus interface 505 provides an interface between bus 500 and receiver 501 and transmitter 503. Receiver 501 and transmitter 503 may be the same component, namely a transceiver, which provides a unit for communicating with various other devices over a transmission medium. Processor 502 is responsible for managing bus 500 and general processing, while memory 504 may be used to store data used by processor 502 when performing operations.
