Blast furnace tapping channel iron falling point castable and preparation method thereof
The invention relates to the technical field of blast furnace tapping channel castable, in particular to a blast furnace tapping channel iron falling point castable and a preparation method thereof. The castable is prepared from the following raw materials: recycled aluminum oxide ceramic, special-grade high-aluminum clinker, corundum, ceramic waste, a carbon material, silicon carbide, a binding agent and an additive, the preparation method comprises the following steps: S1, mixing the recycled aluminum oxide ceramic, the special-grade high-aluminum clinker, the corundum, the ceramic waste, the carbon material, the silicon carbide, the binding agent and the additive to obtain a mixture; s2, performing dry mixing and stirring on the mixture obtained in the step S1, and adding water for mixing to obtain slurry; s3, the slurry obtained in the step S2 is poured into a mold, pouring vibration molding, demolding, drying, heat preservation and cooling are conducted, and the composite material is obtained. The prepared castable is high in high-temperature strength, compact in volume density, high in molten iron seepage resistance, high in scouring resistance, not prone to being bonded with a metal solution and high in thermal shock resistance, oxidation resistance and metal solution corrosion resistance.
本发明涉及一种高炉出铁沟浇注料技术领域，特别是涉及一种高炉出铁沟落铁点浇注料及其制备方法；所述浇注料包括如下原料：回收氧化铝陶瓷、特级高铝熟料、刚玉、陶瓷废料、碳素材料、碳化硅、结合剂、外加剂；制备方法，包括如下步骤：S1、将回收氧化铝陶瓷、特级高铝熟料、刚玉、陶瓷废料、碳素材料、碳化硅、结合剂、外加剂混合，得到混合料；S2、将步骤S1得到的混合料干混搅拌，加水拌合，得到浆料；S3、将步骤S2得到的浆料浇入模内，浇注振动成型，脱模，烘干、保温、冷却，即得。本申请制得的浇注料高温强度高，体积密度致密，抗铁水渗透力强，耐冲刷性强，不易与金属溶液粘结，抗热震性、抗氧化性、抗金属溶液腐蚀性强。
