Series technologies in slag-stopping like “Infrared test for slag-roughing”, “sliding plate in pushing off slag” and the optimization of floating plug have been introduced in this paper. The system operated steadily after install and trial run, have played a good metallurgy effect, and the amount of slag-roughing has been decreased 48.9%, the furnaces ratio of rephosphorization quantity 0.003% have been increased 14.38%, yield of alloy Si and Mn have been increased 1.36% , 1.78% respectively, and decreased the consume of deoxidize material and refining slag effectively. The content of [Ti] in bearing steel have been controlled below 50×10-6, realized the produce of high quality bearing steel that T[O] 8×10-6 [Ti] 30×10-6, and established the important foundation for the exploitation of high quality steel.
