介绍了ML08Al冷镦钢在炼钢过程中的控制及生产情况,包括转炉冶炼过程中合金的选择,硅质量分数控制,吹氩站渣脱氧以减轻精炼炉的脱氧造白渣的压力,严格控制成分等。这些措施解决了连铸时水口堵塞问题,实现了ML08Al冷镦钢的批量生产。
The process route of BOF-LF-CC for producing ML08Al cold heading steel is described in this paper. The technologies adopted in steelmaking process include strict choice of alloy and controlling of silicon content. In addition, slag deoxidation and strict composition control of the steel are implemented at argon blowing station to release the pressure for making white slag. Thanks to these measures, the problem of nozzle blocking has been solved and batch production of ML08Al cold heading steel goes smoothly.
