Wear-resistant material for blast furnace bunker and manufacturing method thereof
The invention relates to a wear-resistant material for a blast furnace bunker and a manufacturing method thereof. The wear-resistant material comprises brown fused alumina leftovers, silica powder, silicon carbide dedusting powder, Portland cement, steel fibers and polycarboxylic acid, wherein the mass percentage of the brown fused alumina leftovers is 10-50%, the mass percentage of the silica powder is 3-8%, the mass percentage of the silicon carbide dedusting powder is 5-12%, the mass percentage of the Portland cement is 20-35%, the mass percentage of the steel fibers is 1-3%, the mass percentage of the polycarboxylic acid is 0.3%, the brown fused alumina leftovers comprise Fe2O3 with a mass percentage of more than or equal to 10%, and the volume density of the brown fused alumina leftovers is greater than or equal to 3.5 g/cm<3>. According to a technical scheme in the invention, the formed wear-resistant material is good in wear resistance, has higher toughness compared with a cast iron plate in the prior art, is high in construction speed and good in integrity in a construction process, and is not limited by the quality guarantee period of glue in construction, so the technical scheme is not limited by service time.
一种高炉矿槽耐磨料及制造方法，其材料包括包括棕刚玉下脚料、硅微粉、碳化硅除尘粉、硅酸盐水泥、钢纤维、聚羧酸；棕刚玉下脚料的质量占比为10‑50％，硅微粉的质量占比为3‑8％，碳化硅除尘粉的质量占比为5‑12％，硅酸盐水泥的质量占比为20‑35％，钢纤维的质量占比为1‑3％，聚羧酸的质量占比为0.3％，棕刚玉下脚料包括质量占比大于等于10％的Fe2O3，棕刚玉下脚料体积密度大于等于3.5g/cm3。本发明技术方案形成的耐磨料的耐磨性好，相对现有技术的铸铁板更加具有韧性，在施工过程中施工速度块，整体性好，且施工不会受到胶水的保质期限制，这样就使得本技术方案不受使用时间限制。
