Unfired magnesia carbon brick
The invention relates to an unfired magnesia carbon brick which comprises the following components in parts by weight: 40-80 parts of 3-5mm large-particle fused magnesia; 30 to 60 parts of large-particle fused magnesite with a particle size of 1 to 3 mm; 30-60 parts of large-particle fused magnesite with the particle size of 0-1 mm; 30 to 60 parts of macrocrystalline fused magnesite with a particle size of 0 to 1 mm; 0.1 to 1 part of 200-mesh tungsten carbide powder; 1-5 parts of phenolic resin; 0.5-5 parts of 200-mesh graphite, and 0.5-5 parts of 200-mesh carbon black. The high-strength thermal-shock-resistant brick is high in strength, high in density and excellent in thermal shock resistance. The direct bonding degree of the large-crystal fused magnesite and the large-particle fused magnesite is high, so that the erosion resistance and the scouring resistance are improved. Periclase crystal phases of the large-crystal fused magnesite and the large-particle fused magnesite complement each other. The enhancement property of the graphite and the dispersity of the carbon black complement each other.
本发明涉及一种免烧镁碳砖，按重量份包括大颗粒电熔镁砂3‑5mm，40‑80份；大颗粒电熔镁砂1‑3mm,30‑60份；大颗粒电熔镁砂0‑1mm,30‑60份；大结晶电熔镁砂0‑1mm，30‑60份；碳化钨粉200目，0.1‑1份；酚醛树脂，1‑5份；石墨200目，0.5‑5份，炭黑200目，0.5‑5份。本申请强度大、致密度高和抗热震性优良。大结晶电熔镁砂，大颗粒电熔镁砂直接结合程度高，提高了抗侵蚀和抗冲刷。大结晶电熔镁砂和大颗粒电熔镁砂的方镁石结晶相相互补充。石墨的增强性与炭黑的分散性互相补充。
