Wet gunning mix for blast furnace
The invention provides a wet gunning mix for a blast furnace. The wet gunning mix comprises the following components in percentage by mass: 30%-43% of alumina particles, 11%-21% of white corundum particles, 11.15%-25.65% of white corundum fine powder, 9%-11% of silicon carbide fine powder, 4%-7% of zirconium composite micro powder, 4%-8% of alpha alumina micro powder, 0.5%-2% of metal silicon powder, 0.5%-2% of titanium carbide fine powder, 3%-5% of a binding agent, 0.01%-0.1% of an anti-explosion agent, 3%-6% of an expanding agent and 0.3%-0.6% of a water reducing agent. According to the blast furnace wet gunning mix, the metal silicon powder and the titanium carbide fine powder are added and react at high temperature to generate a titanium silicon carbide/silicon carbide composite material new phase, and the slag penetration resistance, the strength performance and the scouring resistance of the gunning mix are improved in the modes of filling pores, blocking the gunning mix from being oxidized and the like.
本发明提供一种高炉湿法喷补料，包括以下质量百分比的组分：矾土颗粒30%~43%、白刚玉颗粒11%~21%、白刚玉细粉11.15%~25.65%、碳化硅细粉9%~11%、锆复合微粉4%~7%、α氧化铝微粉4%~8%、金属硅粉0.5%~2%、碳化钛细粉0.5%~2%、结合剂3%~5%、防爆剂0.01%~0.1%、膨胀剂3%~6%和减水剂0.3%~0.6%。该高炉湿法喷补料通过加入金属硅粉和碳化钛细粉，高温下反应生成钛碳化硅/碳化硅复合材料新物相，通过填充气孔、阻挡喷补料氧化等方式提高喷补料的抗熔渣渗透性能、强度性能、耐冲刷性能。
