【摘要】 流动性是保护渣一项重要的物理化学性能。保护渣如果能均匀地流入到结晶器和坯壳之间,将会大大减少铸坯表面缺陷的产生。本文研究了温度、碱度和成分等对保护渣流动性的影响。试验结果表明,温度升高,保护渣流动性变好。TiO₂会恶化保护渣的流动性,保护渣碱度超过一定范围,保护渣流动性可能会变差。更多还原

【Abstract】 Fluidity is an important physical and chemical properties of mold powder.If mold powder can even flow into the shell and the billet,that will greatly reduce the generation of surface defects.In this paper,the influence of temperature, basicity and composition on the mold powder fluidity had been researched.The test results show that the temperature increase, the fluidity of mold powder will become better.TiO₂ will make the fluidity of mold powder worse,basicity of mold powder exceed a certain scope,mobility of mold powder may become worse.更多还原
