a.出现裂纹的轧辊应及时更换,磨前量依据轧辊的磨损程度而定,主要是消除残余裂纹。b.工作辊在使用一个周期后,进行一次消除应力退火,或将磨削后的轧辊浸入具有一定温度的油剂中保存,减小或者消除内应力。c.统筹考虑轧件、轧制压力、接触应力和热膨胀等因素,合理配置辊型,保持轧辊适量均匀磨损。d.依据轧件高温特性,合理分配压下量,杜绝超量压下、不均匀压下及以冲击咬入等操作方法。e.确保冷却液的正常投入及供放时间、位置 a. Cracks in the roll should be promptly replaced, the amount of grinding according to the degree of wear of the roll may be, mainly to eliminate residual cracks. b. After one cycle of work roll, stress relief annealing is performed or the ground roll is immersed in oil with a certain temperature to save, reduce or eliminate internal stress. c. Consideration of rolling, rolling pressure, contact stress and thermal expansion and other factors, a reasonable allocation of roller type, to maintain the right amount of uniform wear roller. d. According to the rolling characteristics of high temperature, reasonable distribution pressure reduction, to eliminate excessive pressure, uneven pressure and impact bite and other methods of operation. e. to ensure the normal liquid coolant and for the release time and location
