Steel ladle castable taking alumina-based homogenized material as matrix
The invention relates to the technical field of refractory castables, and specifically to a steel ladle castable taking alumina-based homogenized material as matrix. The steel ladle castable is prepared by taking the alumina-based homogenized material with the alumina content of 75-80% as an aggregate, and alumina micro-powder, silicon dioxide micro-powder, pure calcium aluminate cement and a binding agent as auxiliary materials, and the content of the alumina-based homogenized material with the particle size larger than 8 mm and smaller than or equal to 25 mm is smaller than or equal to 5%. And the particle size of the binding agent is controlled below 1mm. According to the invention, a raw material grading control technology is combined with a superfine powder technology; the grain composition of the homogeneous material, especially the amount of large particles, is adjusted, so that the overall erosion resistance of the castable is improved, the overall ladle life of a steel ladle is prolonged, the ladle life of an existing steel ladle is prolonged from 110 times to 160 times or above, and more benefits of 4000-6000 tons of steel are brought to users.
本发明涉及耐火浇注料技术领域，具体涉及一种以矾土基均化料为基体的钢包浇注料，由氧化铝含量为75‑80％的矾土基均质料为骨料，辅以氧化铝微粉、二氧化硅微粉、纯铝酸钙水泥、结合剂组成，矾土基均质料中颗粒级配8mm＜粒度≤25mm含量不超过5％；结合剂的粒径控制在1mm以下。本发明通过原料级配的控制技术结合超微粉技术，即调整均质料的颗粒级配，尤其是大颗粒的量，从而提升浇注料的整体抗侵蚀性能，从而提升钢包整体包龄，将现有的钢包包龄由110次提高到160次以上，为使用者多带来4000‑6000吨钢收益。
