Blast furnace tapping channel castable
The invention relates to a blast furnace tapping channel castable, which is characterized by comprising the following components by weight: 15-20 parts of brown fused alumina particles, 10-16 parts ofcompact corundum particles, 10-15 parts of silicon carbide particles, 1-4 parts of a carbon material, 2-6 parts of metal silicon powder, 3-5 parts of silicon carbon micro powder, 10-18 parts of aluminum oxide micro powder, 2-8 parts of alumina hollow spheres, 5-10 parts of high-aluminum fine powder, 2-4 parts of high-alumina cement, 1-2 parts of a composite water reducing agent, 0.4-1 part of anadditive, and 0.3-0.5 parts of explosion-proof fibers. The high-temperature strength, the oxidation resistance and the slag resistance of the castable can be improved conveniently, the castable is prevented from cracking in the baking process, moisture in the castable is discharged conveniently, and the castable is not prone to damage and high in durability.
本发明是一种高炉出铁沟浇注料，其特征在于，其组分按重量份数配比如下：棕刚玉颗粒：15‑20份；致密刚玉颗粒：10‑16份；碳化硅颗粒：10‑15份；碳素材料：1‑4份；金属硅粉：2‑6份；硅碳微粉：3‑5份；氧化铝微粉：10‑18份；氧化铝空心球：2‑8份；高铝细粉：5‑10份；高铝水泥：2‑4份；复合减水剂：1‑2份；外加剂：0.4‑1份；防爆纤维：0.3‑0.5份。本发明本便于提高浇注料的高温强度、抗氧化性和抗渣性，防止浇注料在烘烤的过程发生爆裂，便于排出浇注料中的水分，使得浇注料不易损坏，耐用性高。
