新日铁公司室兰厂过去一直利用铁水罐车式铁水预处理方式进行脱硅、脱磷。这种铁水预处理工艺存在着预处理时间长、不能配合连铸工艺进行超前预处理、预处理能力低等缺点。室兰厂利用待机转炉作为预处理炉 ( 2座转炉体系 )进行研究得出 ,在转炉操作没有受到任何影响的情况下 ,
Nippon Steel Company Muroran factory in the past has been using hot metal ladle carded hot metal pretreatment methods for desilication, dephosphorization. This hot metal pretreatment process there is a long pretreatment, can not be combined with the continuous casting process for advanced preconditioning, low preconditioning shortcomings. Muroran plant using standby converter as a preconditioning furnace (2 converter system) conducted a study concluded that in the converter operation has not been any impact on the circumstances,
