摘要
诚德公司通过采用高振频低振幅振动方式、中间包连续自动测温、结晶器液面自动控制、优化水口形态和插入深度、保护渣调整、恒拉速等连铸工艺技术,大幅提高了304不锈钢连铸坯表面质量,使304不锈钢在高拉速条件下铸坯免修磨率比例超过90%,冷轧剥片率稳定在1%以内。
The continuous casting technology which included vibration mode of higher vibratory frequency and lower amplitude,continuous automatic temperature measuring in tundish,automatic control of mould liquid level,optimizing water gap form and insertion depth,adjustment casting powder and constant casting spee were adopted in Nickel Industry Co.,Ltd.Chengde North Sea.The surface quality of 304 stainless steel slab was improved greatly.The ratio of repair grinding free was more than 90% in higher casting speed,and the ratio of cold rolling delamination was lower than 1%.
