[0019] According to the ratio of the present invention, CaO, CaF 2 After the powder is mixed, it is heated and pre-melted at high temperature, and then mixed with the corresponding proportion of MgCO after cooling and crushing. 3 , CaSi, BaCO 3 It is mixed with Al to obtain the ultra-low sulfur steel pre-melted composite refining slag of the present invention. After being made, it can be packaged in a plastic bag inside, and then packaged in a nylon bag on the outside, and added to the surface of the molten steel during use. It can also be made into cored wire and fed with molten steel. The present invention uses X65, X70 and other Al killed steels as carriers, and successfully carries out production tests of X65 steel and X70 steel (because X80 steel and X70 steel have similar compositions, the slag can also be used to produce X80 and above steel grades). The specific embodiments of the present invention and the results obtained in the experiment are shown in Table 1.
