Manufacturing method of low-thermal-conductivity refractory castable
The invention relates to the technical field of refractory materials, in particular to a manufacturing method of a low-thermal-conductivity refractory castable, which comprises the following steps: crushing large raw materials into crushed materials having a size of 0.5-1cm by a jaw crusher, crushing the crushed materials by a cone crusher until the crushed materials pass through a 50-100-mesh sieve to obtain fine powder; weighing bauxite aggregate, brown fused alumina, white fused alumina, refractory cement, silicon powder and metal oxide in parts by weight, and mixing to obtain a mixture a;weighing glass fibers, asbestos, rock wool and silicate in parts by weight, and mixing to obtain a mixture b; putting the mixture a and the mixture b into a stirrer, uniformly mixing, adding water andan auxiliary agent in parts by weight, and mixing for 20-30 minutes; drying the treated material at 40 to 60 DEG C until the water content is 0.03 to 0.1 percent; and preparing the low-heat-conductivity refractory castable from the treated material in a stepped baking mode. The castable prepared by the method has good fire resistance, and maintains good pressure resistance and wear resistance.
本发明涉及耐火材料技术领域，其具体是一种低导热耐火浇注料制造方法，包括：将各大块原料经颚式破碎机破碎至0.5‑1cm的碎料，之后经锥式破碎机粉碎至其过50‑100目的筛制得细粉；按重量份称取铝矾土骨料、棕刚玉、白刚玉、耐火水泥、硅粉、金属氧化物混合得混合物a；按重量份称取玻璃纤维、石棉、岩棉、硅酸盐混合得混合物b；将混合物a、混合物b置于搅拌机中混合均匀后，按重量份比加入水和助剂，混合20‑30min；将处理的物料于40‑60℃中烘干至含水量处于0.03‑0.1％；将处理后的物料采用阶梯式烘烤的方式制得低导热耐火浇注料；本方法制得的浇注料具有良好的耐火性能，保持了很好的耐压性能和耐磨性能。
