转炉装入量切换冶炼的用氧工艺研究

Study on oxygen supply technologies for switchover of charging load in BOF refining

武钢股份公司要求条材总厂CSP分厂的转炉不仅要向CSP连铸连轧生产线(转炉的装入量为150t)提供钢水,还要随时按计划向条材总厂一炼钢分厂(转炉的装入量为120t)提供钢水,要求CSP分厂的转炉解决装入量切换(120t/150t)冶炼的用氧问题,本文论述了转炉装入量切换(120t/150t)冶炼的用氧工艺问题。

According to the requirements of Wuhan Iron Steel Co.,Ltd,the converter of the CSP Branch of the General Wire Rod Mill shall not only supply hot metal for the continuous casting-continuous rolling line（the charging load of the converter is 150 t）,but also provide hot metal for the No.1 Steel-making Branch of the General Wire Rod Mill at any moment（the charging load of the converter 120 t） and in the meanwhile the CSP Branch shall provide oxygen for switchover of the charging load of the converter（120 t/150 t） in the process of refining.The present paper discusses the oxygen supply technology for the switchover of the charging load（120 t/150 t） of the converter in refining.
