[0002] In the cold rolling production process, high requirements are placed on the qualified rate of finished rolls, especially the surface quality of the rolls. The effective use, reasonable selection and correct setting of grinding program parameters of equipment and facilities are important guarantees for improving the qualified rate of products.

[0003] The working rolls of a single-stand eighteen-roller mill are high-speed steel rolls with a hardness of 86-89HSD. They are ground with resin grinding wheels or ceramic grinding wheels, but the grinding efficiency is low and the surface quality cannot be effectively guaranteed. The grinding time of a single roll is long, and various defects such as white marks, scratches, knife marks, vibration marks, and low roll surface roughness frequently occur during grinding. Repeated processing and grinding result in low grinding efficiency and waste of resources. If roll changes are frequent, the production line will be shut down or slowed down due to insufficient spare rolls, which will directly affect production output and bring economic losses. However, the grinding of high-speed steel rolls is currently mostly based on human experience estimates, and there is still a lack of a more sophisticated and systematic method.

[0033] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0034] In order to solve the problem of lack of a more sophisticated grinding method for high-speed steel rolls, an embodiment of the present invention provides a high-speed steel roll grinding method, such as Figure 1 As shown, the method includes:

[0035] S101, determining the material of the target roll and the feeding considerations, wherein the feeding considerations include the feeding position and the feeding speed;

[0036] S102, determining a grinding wheel abrasive based on the material of the target rolling roller;

[0037] S103, controlling the grinding of the target roll based on the grinding wheel abrasive, the feeding position and the feeding speed.

[0038] Based on the above scheme, the design is carried out from two aspects: the selection of grinding wheel specifications and the setting of grinding process parameters. By resetting the grinding process parameters, grinding defects such as knife marks and chatter marks are controlled, the grinding time is greatly reduced, high-quality and high-efficiency grinding is achieved, and effective utilization of resources is achieved, energy saving and consumption reduction are achieved, the pressure on the backup rollers is reduced, the labor intensity is reduced, and production is safe and stable.

[0039] In one embodiment, the total mass of the target roller is expressed as a percentage, and the target roller includes:

[0040] 0.9%-1.5% carbon, 0.6%-2.0% silicon, 0.3%-1.0% manganese, less than or equal to 0.025% boron, less than or equal to 0.015% sulfur, 7.0%-9.0% chromium, less than or equal to 1.5% tungsten, 1.3%-3.0% molybdenum, 0.3%-3.0% vanadium, the target roll hardness is 86HSD to 90HSD.

[0041] Exemplarily, the target roller material has a chemical composition of: carbon 0.9-1.5%, silicon 0.6-2.0%, manganese 0.3-1.0%, boron ≤0.025%, sulfur ≤0.015%, chromium 7.0-9.0%, tungsten ≤1.5%, molybdenum 1.3-3.0%, and vanadium 0.3-3.0%, and is a high-speed steel roller with a hardness of 86-90HSD.

[0042] In one embodiment, the grinding wheel is a CBN grinding wheel, and the hardness of the CBN grinding wheel is 4800HK.

[0043] For example, the target roll is a high-speed steel roll with a hardness of 86-90 HSD. The target roll hardness is higher than that of an ordinary roll, and high-quality and high-efficiency grinding cannot be achieved using an ordinary corundum grinding wheel. The Knoop hardness of an ordinary corundum grinding wheel is 2000 HK, which is much lower than the Knoop hardness of a CBN grinding wheel of 4800 HK.

[0044] Furthermore, the structure of the CBN grinding wheel is generally composed of three parts: a working layer, a matrix, and a transition layer. According to the chemical composition of the roll, it is determined that the roll is a high-speed steel roll with a hardness of 86-90HSD.

[0045] In one embodiment, the grinding wheel abrasive is cubic boron nitride.

[0046] Exemplarily, the abrasive of the CBN grinding wheel is cubic boron nitride, which will react with carbon at 2000°C, while the temperature of the grinding area is 500-800°C, so no chemical reaction occurs during the grinding process. It is suitable for grinding high-speed steel rolls with a hardness of 80-90HSD made of chilled cast iron.

[0047] Based on the above scheme, the CBN grinding wheel has a high grinding ratio, which is conducive to high-speed grinding. Under the premise of ensuring the removal of the roller fatigue layer, the grinding time of a single roller is reduced from 120 minutes to 50 minutes, and the grinding time of a single roller is shortened by 20%-50%. The CBN grinding wheel can grind high-speed steel rollers with high efficiency, and the roller surface can be scratched zero. The number of rollers that can be ground by a single CBN is equal to 4-12 times the number of single-piece grinding rollers of an ordinary grinding wheel, the coolant life is increased by 5-10 times, the emission of toxic gases is reduced by 95%, and the risk of grinding wheel explosion is zero.

[0048] In one embodiment, the method further includes: setting the feeding position as a primary control factor and the feeding speed as a secondary control factor.

[0049] Exemplarily, the CBN grinding wheel is suitable for grinding high-speed steel rollers. The grinding wheel has high hardness and high grinding ratio. Through the fitting effect analysis of the regression model, this application found that the determination coefficient R2=0.94 of the end feed parameter setting, the model has a high degree of fitting, while the determination coefficient R2=0.68 of the continuous feed, the model has a low degree of fitting. Therefore, the grinding process parameter setting of the CBN grinding wheel is different from that of the ordinary grinding wheel, and the continuous feed does not require large-scale compensation. Therefore, under the premise that the rotation speed of the grinding wheel and the roller is constant, the grinding process parameters of the CBN grinding wheel should take the end feed as the main control factor and the continuous feed as a secondary consideration.

[0050] like Figure 2 As shown, in one embodiment, the feeding portion is end feeding, and the end is greater than or equal to 0.0025 mm.

[0051] like Figure 3 In one embodiment shown, the feed speed is 0.0018 mm / min, and the single feed amount is greater than or equal to 0.0043 mm.

[0052] For example, if the continuous feed setting amount is too large, the grinding current may suddenly "drop" or "disconnect" during the grinding process. For example, the current value of 8A in process 6 may suddenly drop to 4A in process 7, which may cause the processes after process 7 to be unable to effectively remove the deep knife marks or vibration marks and other grinding surface quality defects left by process 6.

[0053] like Figure 4 As shown, the present application takes into account that during the grinding process, the end feed is 0.0025mm + continuous feed is 0.0018mm / min, and the actual maximum grinding amount of a single pass due to continuous feed is greater than 0.0043mm, generally around 0.006mm. After the accumulation of grinding process passes, the actual grinding is magnified. It is for this reason that the next pass or current will be greatly reduced, far from the set expectations, and the preset step grinding current value cannot be achieved, which in turn causes the subsequent processes to be unable to remove the wide knife marks, chatter marks and other roller surface quality defects left in the previous processes.

[0054] Furthermore, the present application takes into account that due to the grinding characteristics of the CBN grinding wheel, changes in the grinding wheel diameter will cause a large change in the grinding current, or even out of control. Therefore, after determining the setting method of end feeding as the main and continuous feeding as the auxiliary, the speed setting corresponding to the consumption of the grinding wheel diameter should also be taken into consideration. Because when the grinding wheel is initially replaced, that is, the grinding wheel diameter is 590-600mm (the grinding wheel diameter usage range is 560-600mm), the grinding current will remain high, and even in the last pass of process 11, the grinding current was as high as 10-13A, and this current value itself will produce quality defects such as spiral lines and vibration lines; when the grinding wheel diameter consumes 560-570mm, there is a sudden "current interruption", "dropping" or "disconnection" during the grinding process, and the current value drops sharply to 5A in process 6, which will cause the processes after process 7 to be unable to effectively remove the spiral lines, vibration lines and other grinding surface quality defects left by the previous process.

[0055] Through analysis, another deep-seated reason in the grinding process is: based on the relationship between linear speed and circumferential speed: V = r·ω

[0056] Assuming the linear speed is constant, the grinding parameters are set at the median value of the grinding wheel diameter of 580 mm. The above 580 is determined based on the average of 560 and 600. When the grinding wheel diameter is large, ω is relatively reduced, the continuous feed is too large, the grinding normal force is reduced, and the feed amount is greater than the actual grinding amount. Therefore, the grinding current is always maintained at a high level;

[0057] Assuming the linear speed is constant, the grinding parameters are set to the median value of the grinding wheel diameter of 580 mm. When the grinding wheel diameter is small, ω increases relatively, the continuous feed is small, the grinding normal force increases, and the feed amount is less than the actual grinding amount. Therefore, the grinding current is "interrupted" and "over-grinding" occurs.

[0058] As a result, the grinding current is "interrupted" and "over-grinding" occurs. A three-stage program control method is adopted. According to the use range of CBN grinding wheel diameter: 560-600mm, it is divided into three stages: 600-580mm is defined as the upper stage, 580-570mm is defined as the middle stage, and 570-560mm is defined as the lower stage. The corresponding grinding wheel speed is set for different diameter ranges. In this way, the entire grinding process can achieve layer-by-layer coverage grinding.

[0059] like Figure 5 As shown, specifically, upper section: grinding wheel diameter 600-580mm, main features:

[0060] 1) The total number of processes is set to 11, with 27 grinding passes;

[0061] 2) The grinding wheel speed is increased to 24m / s for rough grinding, and the number of rough grinding passes is 9 and set as an even number with processes 2 and 3. Processes 1-3 can be regarded as rough grinding. Rough grinding increases the roller speed and increases the grinding capacity;

[0062] 3) Due to the large diameter of the grinding wheel, the number of rough grinding steps was increased to 14, and the excess removal was increased;

[0063] 4) In the intermediate process 6, the continuous feed of deep cutting slow feed compensation is 0.0030mm / min, and the end feed is increased to 0.0022mm. The grinding passes are guaranteed to be even, symmetrical grinding is guaranteed, and roller tilt is avoided. When executing the data parameters, the compensation current value is observed, dynamic control is performed, and reasonable data correction is performed;

[0064] 5) When modifying parameters, they are mainly increased or reduced in the direction where the grinder has strong data execution capabilities;

[0065] 6) For processes with more than 2 passes, ensure that continuous feeding ends in the direction with strong execution capability to ensure that data is executed in place;

[0066] 7) Observe and determine the execution direction of the data. If it is contrary to the preset direction, make corrections by adding or reducing a pass to ensure the final direction of the grinding.

[0067] 8) The continuous feed of process 9-11 is reduced to 0.001mm / min, and the rule of mainly end feed is set;

[0068] 9) After the tailstock is closed, the surface quality of the final grinding roll is ensured by taking advantage of the weak data execution capability.

[0069] Middle section: Grinding wheel diameter 580-570mm, main features:

[0070] 1) The total number of processes is set to 11, with 25 grinding passes;

[0071] 2) The grinding wheel speed is increased to 22 m / s for rough grinding, and the number of rough grinding passes is 8 and set as an even number with processes 2 and 3. Processes 1-3 can be regarded as rough grinding;

[0072] 3) The number of rough grinding steps is maintained at 12, and the excess removal is increased;

[0073] 4) In the intermediate process 6, the continuous feed of deep cutting slow feed compensation is 0.0028mm / min, and the end feed is increased to 0.0018mm. The grinding passes are guaranteed to be even, symmetrical grinding is guaranteed, and roller tilt is avoided. When executing the data parameters, the compensation current value is observed, dynamic control is performed, and reasonable data correction is performed;

[0074] 5) When modifying parameters, they are mainly increased or reduced in the direction where the grinder has strong data execution capabilities;

[0075] 6) For processes with more than 2 passes, ensure that continuous feeding ends in the direction with strong execution capability to ensure that data is executed in place;

[0076] 7) Observe and determine the execution direction of the data. If it is contrary to the preset direction, make corrections by adding or reducing a pass to ensure the final direction of the grinding.

[0077] 8) The continuous feed of process 9-11 is reduced to 0.001mm / min, and the rule of mainly end feed is set;

[0078] 9) After the tailstock is closed, the surface quality of the final grinding roll is ensured by taking advantage of the weak data execution capability.

[0079] Lower section: Grinding wheel diameter 570-560mm, main features:

[0080] 1) The total number of processes is set to 11, with 23 grinding passes;

[0081] 2) The grinding wheel speed is reduced to 18 m / s for rough grinding, and the number of rough grinding passes is 7 and set as an even number with processes 2 and 3. Processes 1-3 can be regarded as rough grinding. Rough grinding reduces the roller speed and reduces the grinding capacity;

[0082] 3) The number of rough grinding steps is maintained at 10 to reduce excess grinding;

[0083] 4) The continuous feed of deep cutting slow feed compensation in the intermediate process 6 is 0.0035mm / min, and the end feed is increased to 0.0025mm. Due to the occurrence of excessive grinding, it is necessary to increase compensation and ensure that the grinding passes are even, ensure symmetrical grinding, avoid roller tilting, observe the compensation current value when executing data parameters, dynamically control, and make reasonable data corrections;

[0084] 5) When modifying parameters, they are mainly increased or reduced in the direction where the grinder has strong data execution capabilities;

[0085] 6) For processes with more than 2 passes, ensure that continuous feeding ends in the direction with strong execution capability to ensure that data is executed in place;

[0086] 7) Observe and determine the execution direction of the data. If it is contrary to the preset direction, make corrections by adding or reducing a pass to ensure the final direction of the grinding.

[0087] 8) The continuous feed of process 9-11 is increased to 0.0014mm / min to achieve effective compensation and ensure smooth grinding;

[0088] 9) After the tailstock is closed, the surface quality of the final grinding roll is ensured by taking advantage of the weak data execution capability.

[0089] Therefore, combined with the grinding characteristics of CBN grinding wheel, the grinding process parameters take end feed as the main control factor and continuous feed as the secondary consideration factor, and the grinding process is expanded from 8 processes to 11 processes. The purpose is to increase the grinding current across the gradient. The control of the overall grinding current follows the law of decreasing linear function to achieve layer-by-layer coverage grinding and effectively remove roller surface defects.

[0090] Based on the above scheme, layer-by-layer coverage grinding is achieved to ensure the stability of the entire process, and the grinding process is fully automated, so that the surface quality uniformity of the entire roller is improved, and the roller curve accuracy is increased from 0.01-0.02mm / m to 0.002-0.004mm / m, which prolongs the online service life of the roller, effectively improves the roller rolling utilization rate, and improves the surface quality of the strip. And because the grinding defects are covered layer by layer between the processes, the grinding defects are effectively removed, and finally the equipment grinding is stable, the labor intensity of the operators is reduced, the quality of each roller is ensured, and the efficiency of the standby roller is improved, thereby ensuring the stable operation of the production line, and also playing a positive role in equipment maintenance.

[0091] In summary, high-quality and high-efficiency grinding of rolls can be achieved, grinding stability can be improved, and full automation of the grinding process can be achieved. The uniformity of the surface quality of the entire roll can be improved, the online service life of the roll can be extended, the rolling utilization rate of the roll can be effectively improved, and the surface quality of the strip can be improved. Through data statistics and analysis, blind setting of grinding program parameters can be eliminated, so that grinding defects can be covered layer by layer between processes and grinding defects can be effectively removed. Ultimately, stable equipment grinding can be achieved, the labor intensity of operators can be reduced, the quality of each roll can be ensured, and the efficiency of standby rolls can be greatly improved, thereby ensuring the stable operation of the production line. At the same time, it also plays a positive role in equipment maintenance.

[0092] Furthermore, as a response to the above Figure 1 In order to realize the method shown in the figure, the embodiment of the present invention also provides a high-speed steel roll grinding device for grinding the above-mentioned Figure 1 The device embodiment corresponds to the aforementioned method embodiment.

[0095] The control unit 23 is used to control the grinding of the target roll based on the grinding wheel abrasive, the feeding position and the feeding speed.

One or more kernels can be set, and a high-speed steel roll grinding method can be implemented by adjusting kernel parameters, which can solve the problem of lack of a more sophisticated grinding method for high-speed steel rolls.
