Production method of novel composite corundum brick for blast furnace
The invention relates to the field of refractory materials, in particular to a production method of a novel composite corundum brick for a blast furnace, which comprises the following steps: pulverizing and screening each raw material to pass through a 100-200-mesh sieve; weighing brown fused alumina, silicon carbide, white fused alumina, mullite, aluminum oxide, chromium oxide, Guangxi white mudand pine needle mullite in parts by weight, and mixing to obtain a mixture a; uniformly stirring the mixture a by using a mixer, feeding the mixture a into a wet mill, adding water, an adhesive and anauxiliary agent in parts by weight, and treating for 20-35 minutes; pressing the treated materials and forming through a 250-350 t pressure forming machine, wherein the density is 2-5 g/cm<3>, then feeding the materials into a drying machine, setting the drying temperature to be 80-110 DEG C, and drying for 1-3 h; and sending the molded material into a roasting furnace, and firing at 1200-2000 DEG C for 8-15 hours to obtain the finished product. The finished product has the advantages of high strength, high temperature resistance, high corrosion resistance and long service life.
本发明涉及耐火材料领域，其具体是新型高炉用复合刚玉砖的生产方法，包括：将各原料经粉碎筛分使其过100‑200目的筛；按重量份称取棕刚玉、碳化硅、白刚玉、莫来石、氧化铝、氧化铬、广西白泥和松针土混合后得混合物a；将混合物a用混合机搅拌均匀后送入湿碾机，按重量份加入水、粘合剂和助剂，处理20‑35min；将处理后的物料用250‑350t的压力成型机压制成型，密度为2‑5g/cm，之后送入烘干机，设置烘干温度为80‑110℃，烘干处理1‑3h；将成型后的物料送入焙烧炉烧制8‑15h，烧制温度为1200‑2000℃，得成品；其成品强度高，耐高温，耐腐蚀能力强，使用寿命长。
