Corundum spinel carbon-free prefabricated part for clean steelmaking
The invention relates to a corundum spinel carbon-free prefabricated part for clean steelmaking, which comprises the following components in percentage by weight: 65-78% of tabular corundum, 3-6% of high-purity magnesium powder, 5-10% of alumina micro powder, 3-7% of hydrated alumina, 0.5-2% of silica powder and 0.1-0.5% of dispersing agent, and the sum of the weight of the components is 100%. The method is high in construction speed, high in strength, stable in thermal shock performance, high in steel slag and molten steel erosion resistance and low in refractory material consumption per ton of steel, and plays roles in cleaning steelmaking, saving raw materials, prolonging the service life, reducing the workload, guaranteeing safety and the like.
一种洁净炼钢用刚玉尖晶石无碳预制件，板状刚玉：65‑78％，高纯镁粉：3‑6％，氧化铝微粉：5‑10％，水合氧化铝：3‑7％，硅微粉：0.5‑2％，分散剂：0.1‑0.5％，以上各组分的组配重量之和为100％；本发明不仅施工速度快，强度高，热震性能稳定，抗钢渣和钢水的侵蚀能力强，吨钢耐材消耗量低，起到了洁净炼钢、节省原材料、提高使用寿命、减少工作量、保安全等方面的作用。
