摘要: 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。

Abstract: The slag-adhering-resistant spraying mix was prepared with recycled material of used Mg-C bricks as main starting material,magnesite clinker as fine aggregate, fused magnesite, SiC, graphite, silicon micro powder and α-Al2O3 micro powder as powder lot, alumina cement as firming agent, sodium hexametahposphate as binder, lignin sulfonic acid calcium as water reducing agent, and polypropylene fiber as anti-explosion agent. The prepared spraying mix is low-cost, slag adhering resistance efficiently and easily to clean up. The industrial test and application of the prepared spraying mix showed that the slag-adhering-cleaned frequency reduced from 2~3 times to 1~2 times per shift, and the slag-adhering-cleaned time decreased from 15~30 min to 10~15 min each time. The application of the spraying mix increased the efficiency of slag-adhering-cleaned and decreased the time of non-production.
Key words: converter, slag adhering resistance, recycled refractory
