description The invention relates to a furnace cover heat-insulating cotton improvement structure for corundum smelting. The furnace cover heat-insulating cotton improvement structure comprises a furnace cover body and heat-insulating cotton arranged inside the furnace cover body and mounted in the mode of being closely attached to a furnace cover. A layer of high-temperature resistant coating is sprayed to the exposed face of the lower side of the heat-insulating cotton and made of high-temperature resistant paint, and raw materials of the paint comprise liquid aluminum dihydrogen phosphate and powdery alumina, with the mass ratio as the benchmark, the mass of liquid aluminum dihydrogen phosphate accounts for 10%-20% of the total mass of aluminum dihydrogen phosphate and powdery alumina, and the spraying thickness of the high-temperature resistant coating is 0.1-1 mm. 本发明涉及种刚玉冶炼用炉盖保温棉改进结构,包括有炉盖本体以及设置于炉盖本体内部并紧贴炉盖安装设置的保温棉,所述的保温棉其下侧的裸露面喷涂有层耐高温涂层,所述的耐高温涂层为种耐高温涂料,且该涂料的原料包括有液态磷酸二氢铝和粉状氧化铝,以质量占比为基准液态磷酸二氢铝占磷酸二氢铝和粉状氧化铝总质量的10%-20%
