选择镁碳耐火材料废砖再生料为主要原料,烧结镁砂为细骨料,电熔镁砂与碳化硅、石墨、硅微粉和α-Al2O3微粉为粉料,矾土水泥为固化剂,六偏磷酸钠为结合剂,木质磺酸钙为减水剂,聚丙烯纤维为防爆剂,通过试验研究,研制了成本低、粘渣隔离效果好、易于清渣的转炉防粘渣喷补料。通过工业性试验和应用,每班炉口粘渣清理次数由2~3次减少到1~2次,粘渣清理时间由每次15~30 min降到了10~15 min,提高了转炉炉口粘渣的清理效率,减少了非生产作业时间。
Select magnesia refractory waste brick as raw material, sintered magnesia as fine aggregate, fused magnesia and silicon carbide, graphite, silica powder and α-Al2O3 powder as powder, alumina cement as curing agent, Sodium metaphosphate as a binder, calcium lignosulfonate as a water-reducing agent, polypropylene fiber as an explosion-proof agent, through the experimental study, developed a low cost, sticky slag isolation effect is good, easy slag removal converter anti-stick slag spray material. Through industrial tests and applications, the number of slag removal per kiln mouth was reduced from 2 to 3 times to 1 to 2 times, and the cleaning time for sticky slag was reduced from 15 to 30 minutes per time to 10 to 15 minutes, The cleaning efficiency of slime reduces the non-productive work time.
