The invention discloses a high-temperature-resistant coating for steel ladles and a preparation method thereof. The high-temperature-resistant coating comprises the following raw materials in percentage by weight: 10-20% of 5-3mm brown fused alumina, 25-35% of 3-1mm brown fused alumina, 15-25% of 1-0mm brown fused alumina, 5-15% of white fused alumina powder, 5-10% of brown fused alumina dedustingpowder, 3-6% of activated alumina micropowder, 1-3% of alumina micro powder, 8-15% of a binding agent and 0.1-0.5% of a dispersing agent. The high-temperature-resistant coating has the beneficial effects that after a steel ladle is newly built or repaired, the coating is sprayed or smeared on a steel ladle working lining, oxidation of the steel ladle working lining can be reduced, erosion of steel ladle slag is reduced, the furnace life of the steel ladle is prolonged, the service life of the steel ladle is prolonged, and great benefits are achieved.
本发明公开了一种钢包用耐高温涂料及制备方法，它包括以下重量百分比的原料：5～3mm棕刚玉10～20％，3～1mm棕刚玉25～35％，1～0mm棕刚玉15～25％，白刚玉粉5～15％，棕刚玉除尘粉5～10％，活性氧化铝微粉3～6％，氧化铝微粉1～3％，结合剂8～15％，分散剂0.1～0.5％；本发明的有益效果：在新砌钢包或者钢包中修完毕后，喷涂或者涂抹到钢包工作衬上，可以减少钢包工作衬的氧化，减少钢包渣的侵蚀，提高钢包的炉龄，延长钢包的使用寿命，有较大的效益。
