Furnace top refractory brick of copper smelting reverberatory furnace
The invention relates to a copper smelting reverberatory furnace top refractory brick which comprises the following raw materials in parts by weight: 40-80 parts of 3-5mm large-particle fused magnesite; 30 to 70 parts of macrocrystalline fused magnesite with a particle size of 3 to 5 mm; 30 to 60 parts of macrocrystalline fused magnesite with a particle size of 0.1 to 1 mm; the particle size of the used refractory brick for the cement kiln is 0.1-1 mm 20 to 40 parts of the raw materials; 1-3 parts of 235-mesh calcium sulfate whiskers; 0.5 to 2 parts of magnesium sulfate powder with a particle size of 0.1 to 0.2 mm; 0.5-2 parts of aluminum polychlorid powder of 200 meshes; and 2-5 parts of 200-mesh sodium alginate powder. The periclase crystal sizes of the raw materials of the large-crystal fused magnesite and the large-particle fused magnesite are different, and the small-size crystal phase and the large-size crystal phase complement each other. The used refractory brick for the cement kiln comprises a mixture of used magnesia-alumina spinel bricks, magnesia-chrome bricks and magnesia-hercynite bricks, so that the use amount of large-crystal fused magnesia and large-particle fused magnesia can be reduced, and natural resources are saved. Meanwhile, the magnesite-chrome bricks and the magnesium-hercynite bricks make up for the defect of high brittleness of macrocrystalline fused magnesite, and the compressive strength of the refractory brick is improved.
本发明涉及一种铜冶炼反射炉炉顶耐火砖，原料按重量份包括：大颗粒电熔镁砂3‑5mm，40‑80份；大结晶电熔镁砂3‑5mm，30‑70份；大结晶电熔镁砂0.1‑1mm，30‑60份；水泥窑用后耐火砖颗粒0.1‑1mm；20‑40份；硫酸钙晶须235目，1‑3份；硫酸镁粉0.1‑0.2mm，0.5‑2份；聚合氯化铝粉200目，0.5‑2份；海藻酸钠粉200目，2‑5份。本发明原料大结晶电熔镁砂和大颗粒电熔镁砂的方镁石结晶尺寸不同，小尺寸晶相与大尺寸晶相相互补充。水泥窑用后耐火砖包括用后镁铝尖晶石砖、镁铬砖及镁铁铝尖晶石砖的混合物，能够减少大结晶电熔镁砂和大颗粒电熔镁砂的用量，节约自然资源。同时镁铬砖及镁铁铝尖晶石砖弥补大结晶电熔镁砂脆性大的缺点，提高耐火砖的抗压强度。
