Slag-stopping wall brick for slag-free tapping of quantum electric arc furnace and preparation method of slag-stopping wall brick
The invention relates to the technical field of refractory materials, in particular to a slag-stopping wall brick for slag-free tapping of a quantum electric arc furnace. The slag-stopping wall brick is prepared from the following raw materials in percentage by weight: 68-80% of macrocrystalline magnesia, 10-18% of crystalline flake graphite, 1-3% of metal aluminum powder, 1-5% of an additive, 2-8% of thermosetting phenolic resin and 2-3% of silica powder. By designing the slag-stopping wall brick for slag-free tapping of the quantum electric arc furnace, the problem that an existing slag-stopping wall brick is too fast in melting loss due to slag erosion and molten steel scouring is effectively solved, so that the melting loss rate of the slag-stopping wall brick of the quantum electric furnace built by the slag-stopping wall brick is low, the consumption of refractory materials per ton of steel of the slag-stopping wall brick can be obviously reduced, and then the overall service life of the quantum electric furnace is longer.
本发明涉及耐火材料技术领域，尤其为一种量子电弧炉无渣出钢用挡渣墙砖，由下述重量百分比的原料制成：大结晶镁砂68～80％、鳞片石墨10～18％、金属铝粉1～3％、添加剂1～5％、热固性酚醛树脂2～8％和硅微粉2～3％，本发明通过设计一种量子电弧炉无渣出钢用挡渣墙砖有效的解决了现有挡渣墙砖因渣侵蚀和钢水冲刷导致熔损过快的问题，从而使挡渣墙砖砌筑的量子电炉其挡渣墙砖熔损速率较低，能明显降低挡渣墙砖的吨钢耐材消耗，进而使量子电炉整体使用寿命更长。
