Blast furnace tapping channel main channel castable added with chromium carbide and preparation method of blast furnace tapping channel main channel castable
The invention provides a blast furnace tapping channel main channel castable added with chromium carbide and a preparation method thereof. The castable comprises the following components in percentage by mass: 40%-50% of white corundum, 10%-20% of chrome corundum, 16%-25% of silicon carbide, 1%-3% of silica fume, 5%-9% of alpha-aluminum oxide, 0.3%-1% of chromium carbide, 0.3%-1% of nickel oxide, 1%-4% of a binding agent, 2%-4% of a carbon material, 0.9%-2.8% of metal silicon powder, 0.1%-0.5% of a dispersing agent and 0.1%-0.5% of an anti-explosion agent. According to the castable, chromium carbide and nickel oxide are added, chromium carbide can react with oxygen to generate chromium oxide, on one hand, oxygen can be consumed, a carbon material is prevented from reacting with oxygen, on the other hand, chromium oxide and nickel oxide form nickel-chromium spinel at high temperature, a compact ceramic layer is formed, the material is more compact, and the castable is further prevented from being oxidized.
本发明提供一种添加碳化铬的高炉出铁沟主沟浇注料及其制备方法，浇注料包括以下质量百分比的组分：白刚玉40%‑50%、铬刚玉10%‑20%、碳化硅16%‑25%、硅灰1%‑3%、α‑氧化铝5%‑9%、碳化铬0.3%‑1%、氧化镍0.3%‑1%、结合剂1%‑4%、碳素材料2%‑4%、金属硅粉0.9%‑2.8%、分散剂0.1%‑0.5%、防爆剂0.1%‑0.5%。该浇注料加入了碳化铬和氧化镍，碳化铬可与氧气反应，生成氧化铬，一方面可消耗氧气，防止碳素材料与氧气反应，另一方面氧化铬在高温下与氧化镍形成镍铬尖晶石，形成致密的陶瓷层，使材料更加致密，进一步防止浇注料被氧化。
