乌柱尔重机厂,在生产中,使用和分析了深淬透性的轧辊钢9X2MΦ、75XM,对大型轧辊钢的质量和组织进行了研究,同时对轧辊的强度和应力状态也作了研究.改进和掌握大型工作辊和支承辊的工频感应加热淬火问题,主要目的是提高加热到组织转变温度时的热透深度,以达到强化和在最大深度中残余应力的合理分布.为保证薄板轧机的质量,要求轧辊的最高硬度为Hs90～102.同时改进轧辊的热处理工艺方面;以及提高轧机材料的质量和均匀性;轧辊的使用性能也作了研究.
Uzbek Heavy Machinery Plant, in the production, the use of and analysis of the deep hardenability of the roll steel 9X2MΦ, 75XM, the quality and organization of the large roll steel was studied at the same time, the strength of the roll and the stress state were also studied . To improve and master large work roll and back-up roll frequency induction heating quenching problems, the main purpose is to increase the heat transfer to the tissue when the heat penetration depth, in order to achieve strengthening and the maximum depth of the residual stress reasonable distribution. In order to ensure that the sheet The quality of the rolling mill requires the highest hardness of the roll Hs90 ~ 102. At the same time to improve the roll heat treatment process; as well as improve the quality and uniformity of mill materials; roll performance has also been studied.
