Cementing material for steel ladle and preparation method thereof
The invention discloses a cementing material for a steel ladle and a preparation method of the cementing material, and belongs to the technical field of refractory materials, limestone, alumina, kaolin and fly ash which are proportioned are used as raw materials, calcined and then mixed with anhydrous calcium sulfate again, a cement material with good fire resistance is obtained, the bonding effect of chrome corundum particles and magnesia particles is improved, and the service life of the cementing material is prolonged. The silica micropowder has a good filling effect, and the mixing degree of all the materials is increased through the dispersion effect of the dispersing agent, so that the cementing material is uniform in property; the alpha-aluminum oxide micro powder and the rho-aluminum oxide micro powder can improve the bonding effect after the chrome corundum particles and the magnesia particles are sintered, the water reducing agent can reduce the water consumption of the cementing material and increase the viscosity, the tackifier can further increase the viscosity of the cementing material, and the carbon fiber powder is matched for use, so that the cementing material is not easy to crack after being dried; the collapsing degree of the dried cementing material is smaller, the bonding performance is better, and the bonding strength of the base and the bottom brick of the sintered steel ladle meets the use requirement.
本发明公开了一种钢包用胶结料及其制备方法，属于耐火材料技术领域，通过配比后的石灰石、矾土、高岭土和粉煤灰为原料，煅烧后与无水硫酸钙再次进行配料，获得耐火性能良好的水泥料，增加铬刚玉颗粒和镁砂颗粒的粘结效果，二氧化硅微粉起到良好的填充作用，通过分散剂的分散作用增加各物料的混匀度，使胶结料性质均一；α‑氧化铝微粉、ρ‑氧化铝微粉可以增加铬刚玉颗粒和镁砂颗粒烧结后的结合效果，减水剂可以减少胶结料的用水量，增加粘度，增粘剂进一步增加胶结料的粘性，碳纤维粉末的配合使用，使胶结料干燥后不易产生裂纹，胶结料干燥后的坍缩程度更小，粘结性能更佳，烧结后钢包的底座与底砖的结合强度满足使用要求。
