Castable for ladle slagging-off plate, ladle slagging-off plate and preparation method of ladle slagging-off plate
The invention provides a castable for a ladle slagging-off plate, the ladle slagging-off plate and a preparation method of the ladle slagging-off plate. The castable for the ladle slagging-off plate comprises the following components: 50-65 parts of mullite, 15-30 parts of andalusite, 3-12 parts of alumina, 2-8 parts of silicon carbide, 2-8 parts of aluminum oxide, 2-5 parts of zirconite, 0.5-2 parts of steel fiber, 2-5 parts of pure calcium aluminate cement, 0.6-1.2 parts of silica powder, 0.5-2.5 parts of carbon microspheres and 0.06-0.16 part of a water reducing agent. The carbon microspheres are used as the additive to be added into the castable for the ladle slagging-off plate, so that the wettability of molten iron, slag, a desulfurizing agent and the surface of a castable matrix can be effectively reduced. Then zirconite is added into the castable for the ladle slagging-off plate to be decomposed into zirconium dioxide and a fused quartz phase under the high-temperature condition, and the zirconium dioxide can improve the toughness and the thermal shock stability of the material; moreover, the fused quartz can react with aluminum oxide in a matrix under a high-temperature condition to generate mullite, so that the mechanical strength and the erosion resistance of the material are improved, and the improvement of the erosion resistance and the strength of the material is promoted.
本发明提供了一种铁水包扒渣板用浇注料、铁水包扒渣板及其制备方法，铁水包扒渣板用浇注料包括以下组分：50～65份莫来石，15～30份红柱石，3～12份矾土，2～8份碳化硅，2～8份氧化铝，2～5份锆英石，0.5～2份钢纤维和2～5份纯铝酸钙水泥；0.6～1.2份硅微粉，0.5～2.5份碳微球和0.06～0.16份减水剂。本发明采用碳微球作为添加剂加入铁水包扒渣板用浇注料中能有效降低铁水、渣质以及脱硫剂与浇注料基质表面的浸润性。将锆英石加入至铁水包扒渣板用浇注料中高温条件下分解生成二氧化锆和熔融石英相，二氧化锆可提升材料的韧性和热震稳定性；熔融石英可与基体中氧化铝在高温条件下反应生成莫来石，从而提升材料的机械强度和抗侵蚀性能，促进材料抗侵蚀性及强度的提升。
