Environment-friendly converter tapping hole repairing material and preparation method thereof
The invention relates to an environment-friendly converter tapping hole repairing material and a preparation method thereof, and the environment-friendly converter tapping hole repairing material comprises the following components in parts by weight: 60-80 parts of fused white corundum, 35-50 parts of fused magnesia particles, 25-35 parts of fused magnesia fine powder, 20-30 parts of synthetic magnesia-calcium sand, 10-25 parts of alumina, 10-15 parts of silicon carbide powder, 8-15 parts of tabular corundum, 5-15 parts of alumina powder, 2-15 parts of asphalt powder, 5-15 parts of tar, 1-5 parts of ethylene glycol and 1-5 parts of N-methyl pyrrolidone. And 0-5 parts of o-xylene. The tar asphalt and the additive are adopted, so that the repairing material has high strength and long service life, and the technical problems that the repairing material combined with the tar asphalt is poor in fluidity and long in sintering time and has a large amount of smoke dust are solved.
本发明涉及一种环保型转炉出钢口修复料及其制备方法，其成分按重量份配比组成：电熔白刚玉60～80份，电熔镁砂颗粒35～50份，电熔镁砂细粉25～35份，合成镁钙砂20～30份，矾土10～25份，碳化硅粉10～15份，板状刚玉8～15份，氧化铝粉5～15份，沥青粉2～15份，焦油5～15份，乙二醇1～5份，N‑甲基吡咯烷酮1～5份，邻二甲苯0～5份。通过采用焦油沥青和添加剂，使得修复料具有高强度，长寿命的同时，还克服了焦油沥青结合的修复料存在的流动性差，烧结时间长，且有大量烟尘的技术难题。
