Electric furnace cover and preparation method thereof
The invention belongs to the field of metallurgical refractory materials, and discloses an electric furnace cover and a preparation method thereof.The electric furnace cover is prepared from, by weight, 10-20 parts of M70 mullite with the particle size being 8-5 mm, 15-25 parts of M70 mullite with the particle size being 5-3 mm, 10-28 parts of tabular corundum with the particle size being 3-1 mm, 15-22 parts of tabular corundum with the particle size being 1-0 mm, 1-8 parts of silicon carbide with the particle size being 1-0 mm and 8-18 parts of fused white corundum with the particle size being 120 meshes. The refractory material comprises the following components in parts by weight: 1-3 parts of fused zirconium mullite with the particle size of 65 meshes, 1-5 parts of fused white corundum with the particle size of 180 meshes, 2-10 parts of CL370 corundum micro powder, 5-10 parts of alpha-aluminum oxide, 1-5 parts of silicon carbide with the particle size of 240 meshes, 0-5 parts of silica fume, 0-1 part of an additive, 1-3 parts of steel fibers and 0-1 part of explosion-proof fibers. A cement-free binding agent is adopted, M70 mullite, fused zirconium mullite, SiC and the like with excellent thermal shock resistance are comprehensively adopted, the physical and chemical product performance of the electric furnace cover is greatly improved, the service life is longer, meanwhile, a chromium-free technology is adopted, no toxic and harmful substances such as chromium oxide are discharged in the production process, the environment-friendly effect is achieved, and the environment-friendly requirement is met.
本发明属于冶金耐火材料领域，公开一种电炉盖及其制备方法，电炉盖包括以下重量份原料组分：粒径8‑5mmM70莫来石10‑20份，粒径5‑3mmM70莫来石15‑25份，粒径3‑1mm板状刚玉10‑28份，粒径1‑0mm板状刚玉15‑22份，粒径1‑0mm碳化硅1‑8份，粒径120目电熔白刚玉8‑18份，粒径65目电熔锆莫来石1‑3份，粒径180目电熔白刚玉1‑5份，CL370刚玉微粉2‑10份，α‑氧化铝5‑10份，粒径240目碳化硅1‑5份，硅灰0‑5份，添加剂0‑1份，钢纤维1‑3份，防爆纤维0‑1份。本发明采用无水泥结合剂，综合采用抗热震性能优良的M70莫来石、电熔锆莫来石、SiC等，电炉盖理化产品性能得到较大改善，使用寿命更高，同时采用无铬技术，生产过程无氧化铬等有毒有害物质排放，对环境友好，满足环保要求。
