Ladle slag line brick for smelting high alloy steel and preparation method thereof
The invention discloses a steel ladle slag line brick for smelting high alloy steel, the steel ladle slag line brick comprises main raw materials and auxiliary materials, the main raw materials comprise 55-70% of an electric smelting macrocrystalline magnesia material, 5-15% of an electric smelting zirconium spinel material, 0.5-1% of a calcium aluminate material, 5-15% of an electric smelting barium zirconate material, 12-17% of a high-purity graphite material and 1-3% of an antioxidant, the auxiliary materials are phenolic resin binders, and the phenolic resin binders account for 2-4% of the mass of the main raw materials; the particle size range of the fused macrocrystalline magnesia material is 8-0.5 mm, the particle size range of the fused zirconium spinel material is 0.5-0.1 mm, and the particle size range of the fused barium zirconate material is 0.1-0.045 mm. The reaction of magnesia and carbon in the slag line brick is reduced, the compact structure of the slag line brick is reserved, and the service life is prolonged by more than 30% compared with that of a magnesia carbon brick.
本发明公开了一种冶炼高合金钢用钢包渣线砖，包括主原料和辅料，主原料包括55～70%电熔大结晶镁砂材料、5～15%电熔锆尖晶石材料、0.5～1%的铝酸钙材料，5～15%电熔锆酸钡材料、12～17%高纯石墨材料、1～3%抗氧化剂，辅料为酚醛树脂结合剂，酚醛树脂结合剂为主原料质量的2～4%；所述电熔大结晶镁砂材料的粒度范围为8～0.5mm，所述电熔锆尖晶石材料粒度范围为0.5～0.1mm，所述电熔锆酸钡材料粒度范围为0.1～0.045mm。渣线砖中的镁砂和碳的反应减少，渣线砖的致密结构得以保留，使用寿命比镁碳砖提高30%以上。
