| 摘 要： | 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。

| Abstract: | In this paper, the role of BaO in mold powder used in continuous casting of steel is studied. The pricipal content of the study is about the effect of BaO on melting temperature, Viscosity, and capacity of absorbing inclusion and glassing of molten mold powder.
Experiment results reveal that to add BaO into mold powder can decrease the melting temperature and viscosity, and prevent the formation of high melting point particle and crystallizing of mold powder, suitable BaO content in mold powder is quite helpful to increase the capacity of absorbing inclusion of molten mold powder, and to improve the lubrication effect of molten powder film between mold and billet. |
