Based on industrial tests in Nan Steel,experiments were carried out to study the effect of single and double slag processes on dephosphorization of molten steel,the effect of different operating system on phosphorus content in molten steel,the effect of adding amount of auxiliary materials on phosphorus content in molten steel at the end point of smelting,and the effect of retained slag process on preliminary slag and phosphorus content in molten steel at the end point of smelting.The experimental results show that compared with the single slag process,the double slag process show better performance on dephosphorization in the preliminary stage,and it can fully meet the requirements of low phosphorus steel at the end point of smelting.In addition,the optimum smelting temperature,alkalinity,and FeO percentage etc.for low phosphorus steel smelting were determined in field tests.It can be concluded that it is better to smelt the steel which has strict requirements on phosphorus content with the double slag process.
