Abstract Aiming at the problem of steel-slag reaction in the continuous casting of high-Titanium steel and the variation of slag properties before and after reaction, in the current study the mold slag for casting high-Titanium steel was focused on. The reactivity of the high-titanium steel and mold slags was studied through experiments, and the changes of composition and properties of two continuous casting slags with different TiO₂ contents before and after reaction were compared. Experimental results show that, with the Titanium content in steel of 0.68% and the increase of the TiO₂ content in slag from 10% to 15%, the steel-slag reaction occurred between Titanium in steel and oxide components in slag, but the reaction was obviously inhibited. After the steel-slag reaction, the melting point, viscosity and breaking temperature of mold slags increased slightly. Crystalline phases of these slags were mainly LiTiO₂ and BaTiO₃, and changed less before and after the steel-slag reaction.

Key words： high titanium steel mold fluxe steel-slag reaction physical and chemical property crystal phase
