Magnesia carbon brick for Consteel electric furnace smelting
The invention discloses a magnesia carbon brick for Consteel electric furnace smelting. The magnesia carbon brick is characterized by being prepared from the following raw materials in parts by weight: 70 to 80 parts of fused magnesite formed by mixing a granular material and a powder material, 12-18 parts of graphite with a particle size smaller than or equal to 0.1 mm, 1-2 parts of metal aluminum with a particle size smaller than or equal to 0.3 mm, 2-4 parts of metal silicon with a particle size smaller than or equal to 0.3 mm, 1-2 parts of high-temperature asphalt with a particle size smaller than or equal to 0.1 mm, 2.5-4 parts of phenolic resin and 0.9-1.3 parts of an inhibitor with a particle size smaller than or equal to 0.08 mm. The magnesia carbon brick is high in slag etching resistance, good in integrity in a continuous high-temperature state, insensitive to oxidation reaction, and capable of resisting the impact of steel and iron materials.
本发明公开了一种Consteel电炉冶炼用镁碳砖，其特征在于：由下列原料按照重量份配比制备而成：颗粒料、粉料混合而成的电熔镁砂70‑80份,粒度≤0.1mm的石墨12‑18份,粒度≤0.3mm的金属铝1‑2份,粒度≤0.3mm的金属硅2‑4份,粒度≤0.1mm的高温沥青1‑2份,酚醛树脂2.5‑4份,粒度≤0.08mm的抑制剂0.9‑1.3份。本发明抗渣浸蚀能力强、持续高温状态下制品的完整性好、对氧化反应冷淡、抗钢铁料冲击。
