本文研究了BaO在连铸结晶器用保护渣中的作用。重点考虑了BaO对保护渣的熔化温度、粘度、吸收夹杂能力和玻璃态形成的影响。 实验结果表明,保护渣中含有一定数量的BaO,可以降低其熔化温度、粘度,阻碍渣中高熔化温度质点的形成及熔渣的结晶,因而将增加保护渣吸收夹杂的能力,改善熔渣膜在结晶器与铸坯间的润滑。 This paper studies the role of BaO in mold powder for continuous casting mold. The effect of BaO on the melting temperature, viscosity, absorption inclusion ability and glass formation of the mold fluxes is mainly considered. The experimental results show that the inclusion of a certain amount of BaO in the mold powder can reduce the melting temperature and viscosity of the slag, hinder the formation of high melting temperature particles in the slag and the crystallization of the slag, thereby increasing the ability of the slag to absorb inclusions, Mold and casting between the lubrication.
