介绍了进口结晶器保护渣在安钢超宽板坯连铸机开机和调试期间的应用情况,肯定了进口保护渣对开机和生产调试所起的作用;通过对进口保护渣的理化指标和使用情况对照分析,生产出小批量的试验用渣,再通过分析试验保护渣的热流密度、液渣层厚度、吸收夹杂物的能力以及钢中合金元素的影响、板坯表面质量等情况,调整出适用于普碳钢、合金钢和不同拉速的保护渣。在宽板坯连铸机上实现了保护渣的国产化。
Introduced the application of imported mold powder in the startup and commissioning of the ultra wide slab caster in Anyang Iron and Steel Co., Ltd., and affirmed the role played by the import of mold flux on start-up and production commissioning. Through the physical and chemical indexes and the use of the imported mold flux, The situation of comparative analysis to produce a small batch of test slag, and then through the analysis of test flux flux density, liquid slag layer thickness, the ability to absorb inclusions and alloying elements in steel, slab surface quality, adjust For general carbon steel, alloy steel and different casting speed slag. In the wide slab caster to achieve the localization of mold powder.
