Refractory material for smelting low-oxygen steel and preparation method thereof
The invention relates to a refractory material for smelting low-oxygen steel and a preparation method thereof. According to the technical scheme, 60-75 wt% of calcium-carbon particles, 15-25 wt% of calcium-carbon fine powder, 2-10 wt% of a spinel-calcium aluminate multiphase material and 2-5 wt% of calcium hydroxide serve as raw materials, an aluminum titanate solution accounting for 2-6 wt% of the raw materials is added, stirring and compression molding are conducted, then vacuum drying is conducted for 8-24 hours at the temperature of 120-300 DEG C, cooling is conducted, and the refractory material for low-oxygen steel smelting is prepared. The refractory material has the characteristics of simple process and low cost, and the prepared refractory material for low-oxygen steel smelting has strong capability of adsorbing oxide inclusions in molten steel, and is a high-quality refractory material for low-oxygen steel smelting.
本发明涉及一种低氧钢冶炼用耐火材料及其制备方法。其技术方案是：以60～75wt％钙碳颗粒、15～25wt％钙碳细粉、2～10wt％尖晶石‑铝酸钙复相材料和2～5wt％的氢氧化钙为原料，外加所述原料2～6wt％的铝钛酸酯溶液，搅拌，压制成型，然后在120～300℃条件下真空干燥8～24小时，冷却，制得低氧钢冶炼用耐火材料。本发明具有工艺简单、成本低的特点，所制备的低氧钢冶炼用耐火材料吸附钢水中氧化物夹杂的能力强，是低氧钢冶炼用优质耐火材料。
