摘　　要：连铸用耐火材料(如浸入式水口和吹气上水口)对钢材质量有很大影响。本文介绍了一种合适的浸入式水口结构,使钢水能够在结晶器中流动,以及吹气上水口在夹杂物中浮动,提高钢包保护罩垫片密封性能方面的性能。通过改进这些连铸用耐火材料,可以提高钢的质量和耐火材料的耐久性。Refractories for continuous casting such as the submerged entry nozzle and gas-blowing upper nozzle considerably influence steel quality. In this article, a suitable submerged entry nozzle structure that allows dersirable molten steel flow in the mold, and suitable properties of the gasblowing upper nozzle in terms of inclusion floating, improving seal-ability of gasket of ladle shroud are descirbed. By improving these refractories for continuous casting, it is possible to improve steel quality as well as refractory durability.
