延長軋輥使用期限,是提高軋鋼机生产能力及降低产品成本的重要措施之一。增高軋輥孔槽的耐磨性,可保証軋制品的高度精确性及改为以負公差进行工作。由于軋輥槽孔耐磨性的增高,同时也减少了軋輥槽孔修正的工作量,这样可减少軋輥的总数和减少制造新軋輥的費用。提高軋輥耐磨性的方法很多,其中最簡單和效果最好的方法是堆焊。苏联亞速鋼厂等用管状焊条及AH-20熔剂堆焊3X2B8合金鋼,使軋輥寿命平均提高11.5倍,
To extend the life of the roll is one of the important measures to improve the rolling mill production capacity and reduce product costs. Increase the wear resistance of the roller groove, to ensure a high degree of precision rolling products and to work with negative tolerance. Due to the increased wear resistance of the roll slots, it also reduces the amount of work required for roll slot correction, which reduces the total number of rolls and reduces the cost of manufacturing new rolls. There are many ways to improve the wear resistance of the roll, of which the most simple and effective method is surfacing. Soviet Union and Asia-speed steel mills and other tubular electrodes and AH-20 flux surfacing 3X2B8 alloy steel, the average life of the roller 11.5 times,
