摘要
在生产 2 0 g(Ti)、410 A、410 B过程中 ,通过冶炼成分的优化 ,钢水净化 ,控制开轧温度、终轧温度及过程变形温度 ,细化晶粒、改善钢板组织 ,解决了锅炉板冲击韧性和时效问题 ,提高了锅炉板合格率。
In the production of 20g(Ti)、410A、410B,the problems of impact toughness and strain aging toughness were resolved by optimizing chemical composition,purification of molten steel,temperature control of the start,final rolling and reduction course,refining the grain size and improving the microstructure of plate.The qualification rate of boiler plate was increased.
