摘　　要：分析了宝钢宽厚板所需连铸板坯保护渣的使用特点,跟踪、分析进口保护渣的使用效果,探讨了不同组元成分、碱度等对保护渣粘度、结晶率的影响规律,开发出适合宽厚板铸机特点的高碱度、低粘度、高结晶化速率的国产保护渣,经现场使用,表明开发的保护渣性能已达到进口保护渣的性能指标。The characteristic of the powder in Baosteel heavy slab continuous caster was analyzed, and the effect of import powder was investigated. Some influences were discussed of different components and basicity. A new home-produced powder with higher basicity, lower viscosity, higher crystallization property for heavy slab continuous caster was developed, which virtue was as same as the import powder.
