韶钢中厚板生产线除鳞系统优化改进
|
摘要
韶钢在中厚板生产中遇到各种除鳞问题,通过原因分析,提出相应的改进措施。针对生产效率提高后高压水除鳞系统流量不足、坯料厚度变化后除鳞箱除鳞效果差等现象,分别采用增设蓄能罐和自动升降除鳞箱的方法,同时根据薄规格钢板的除鳞要求,增加精除鳞集管数量。各项措施实施后,提高了除鳞质量,降低了除鳞能耗,达到了预期目的。
Shaogang encounters various descaling problems during production of medium and heavy steel plate,but raises relevant improvement measures after cause analysis.For the cases of insufficient flow of high pressure water descaling system after productivity increase and poor descaling result of primary descaler after thickness changing of slabs,the company adopts the methods of adding accumulators and automatic height adjustment,and increases the quantity of finish descaling headers in accordance with the descaling requirements of light gauge steel plate.After implementation of various measures,descaling result is improved while the descaling energy consumption is reduced.
