Development and Application of Casting Flux for Bloom Continuous Casting of Medium and Low Carbon Steel
-
摘要: 在借鉴国内外研究经验的基础上,结合攀钢中低碳钢方坯连铸工艺条件,在实验室进行了保护渣结晶与玻璃化特性协调、吸收夹杂物能力及配碳模式等方面的研究,确定了合理的渣系及物理性能、化学成分。工业试验结果表明,研制的保护渣能够满足工艺要求,可以取代进口保护渣。Abstract: Based on the research works of home and abroad, a casting flux was developed according to the bloom continuous casting process of medium and low carbon steel at PZH Steel. The coordination of glasslike-crystal property, capacity of absorbing inclusions and carbon mixing technology of casting flux were researched as key contents in laboratory, a reasonable slag system of casting flux for medium and low carbon steel bloom continuous casting were determined. Industrial-scale experiments showed that the developed casting flux could meet the technological requirements of the bloom continuous casting.
