The invention relates to the technical field of refractory materials, and concretely relates to a steel ladle castable for integral pouring, and a preparation method of the steel ladle castable. The castable is prepared from, by weight, 20 to 30 percent of white corundum, 34 to 55.34 percent of tabular corundum, 22 to 29 percent of spinel, 3 to 10 percent of aluminum oxide micro powder, 2 to 10 percent of a binding agent, 0.1 to 1 percent of a water reducing agent and 0.01 to 0.1 percent of an explosion-proof agent. The compactness of a working lining poured by the castable disclosed by the invention is remarkably improved, better slag corrosion resistance and permeability are embodied, and the service life of a whole steel ladle is prolonged and improved to a greater extent. According to the invention, the thermal shock resistance of the castable for the integral casting working lining of the steel ladle can be improved.
本发明涉及耐火材料技术领域，尤其涉及一种整体浇注用钢包浇注料及其制备方法。其中，浇注料包括按重量份计的以下原料：白刚玉20～30％、板状刚玉34～55.34％、尖晶石22～29％、氧化铝微粉3～10％、结合剂2～10％、减水剂0.1～1％和防爆剂0.01～0.1％。本发明的浇注料浇注后的工作衬致密性显著提高，体现出较好的抗渣侵蚀性和渗透性能，使整个钢包的使用寿命得到较大程度的提高和改善。本发明能够提高钢包整体浇注工作衬用浇注料的抗热震性能。
