CaC2-C refractory material for refining furnace and preparation process thereof
The invention relates to a novel CaC2-C refractory material which mainly comprises 40-98% of calcium carbide, 2-60% of carbon and 2-10% of an anhydrous resin binder. The preparation method comprises the following steps of: proportioning according to a certain particle ratio, and carrying out mixing, high-pressure forming, coating and curing treatment to obtain a calcium carbide carbonaceous unfired product. The material is particularly suitable for a steel refining furnace lining slag line with vacuum. The material has the characteristics of molten steel corrosion resistance, oxidation resistance, vacuum resistance and CaF2-containing slag corrosion resistance, has very long service life, and also has the effects of desulfurization, deoxidation and molten steel cleaning.
本发明涉及一种新型CaC2‑C质耐火材料，其主要是由40~98%的电石和2~60%的碳组成的，外加2~10%的无水树脂结合剂。按一定颗粒配比进行配料，经过混料、高压成型、涂层和固化处理的方法制成电石碳质不烧制品。该材料特别适用于带真空的钢铁精炼炉衬渣线。它具有抗钢液熔蚀、抗氧化、抗真空和抗含CaF2渣侵蚀的特点，具有非常高的使用寿命，同时还具有脱硫、脱氧和洁净钢水的作用。
