摘要
介绍了38MnVS6钢的生产工艺流程,针对生产过程中夹杂物超标的问题,进行了一系列的工艺优化。通过优化转炉冶炼工艺、采用合适的精炼渣系、优化钢水增氮工艺、完善连铸保护浇注等措施,38MnVS6钢的纯净度得到大幅提升,夹杂物合格率达到了99.2%,满足了客户的需求。
The production process of 38MnVS6 steel was introduced.Aiming at the excessive inclusions in the production process,a series of process optimization were carried out.By optimizing converter smelting process,adopting appropriate refining slag system,optimizing molten steel nitrogen increasing process and continuous casting protective pouring,the purity of 38MnVS6 steel has been greatly improved,and the qualified rate of inclusions has reached 99.2%,meeting the needs of customers.
