CSP薄板坯连铸高碳钢用结晶器保护渣
摘要：
本发明公开了一种CSP薄板坯连铸高碳钢用结晶器保护渣，属于保护渣技术领域，其化学成分及其重量百分含量3%，为N：aC2OaO：9：%3~51%1~%3，8F%-，：S1i0O%2~：1258%%，~C31：%4，%L~8i%2O，余：1量%~为2.5不%，可A避l2O免3：的1%杂~质。本发明保护渣综合性能优异，在结晶器内能合适铺展，熔化均匀，形成稳定状态的初始渣层-烧结层-半熔渣层-熔渣层的多层结构；渣面活跃，无卷渣现象发生；热流曲线稳定，所浇注铸坯表面、皮下及内部质量优异。
摘要（英）：

The invention discloses CSP compact strip production high-carbon steel crystallizer casting powders, and belongs to the technical field of casting powders. The chemical components and weight percentage composition of the casting powders are 35%-38% of CaO, 28%-31% of SiO2, 1%-2.5% of Li2O, 1%-3% of Al2O3, 9%-11% of Na2O, 10%-15% of F<->, and 4%-8% of C, and the balance being inevitable impurities.Combination property of the casting powders is excellent, and the casting powders can be properly spread in a crystallizer, and uniformly fused, to form a stable state multi-layer structure of initial slag layer-sinter layer-semiclinker layer-clinker layer. The top of slag is active, and slag entrapment phenomenon would not occur, and a heat flux curve is stable, and quality of a poured casting blank surface, a poured casting blank under a surface, and internal quality are excellent.
