Steel ladle wall castable containing white corundum dedusting powder and preparation method of steel ladle wall castable
The invention belongs to the technical field of steel smelting and refractory materials, and particularly relates to a steel ladle wall castable containing white corundum dedusting powder and a preparation method of the steel ladle wall castable. The steel ladle wall castable is mainly prepared from the following raw materials in parts by mass: 10 to 40 parts of 90 alumina, 10 to 40 parts of white corundum, 3 to 10 parts of fused magnesite, 5 to 20 parts of white corundum dedusting powder, 2 to 9 parts of pure calcium aluminate cement, 3 to 12 parts of alpha-alumina micro powder, 0.04 to 0.15 part of sodium tripolyphosphate, 0.01 to 0.04 part of metal aluminum powder and 0.1 to 0.6 part of organic fiber. The white corundum dedusting powder is introduced into the steel ladle wall castable to replace white corundum fine powder, so that the prepared steel ladle wall castable has the characteristic that the service life is equivalent to that of an original steel ladle wall castable, and the manufacturing cost of an enterprise is reduced; and moreover, the environmental protection problem of white corundum enterprises is correspondingly solved by recycling the wastes, and meanwhile, the consumption of non-renewable resource of non-renewable bauxite ore can also be reduced.
本发明属于钢铁冶炼及耐火材料技术领域，具体涉及一种含白刚玉除尘粉的钢包包壁浇注料及其制备方法。主要包括如下质量份的原料：90矾土10‑40份，白刚玉10‑40份，电熔镁砂3‑10份，白刚玉除尘粉5‑20份，纯铝酸钙水泥2‑9份，α‑氧化铝微粉3‑12份，三聚磷酸钠0.04‑0.15份，金属铝粉0.01‑0.04份，有机纤维0.1‑0.6份。本发明通过在钢包包壁浇注料中引入白刚玉除尘粉替代白刚玉细粉，从而制备出的钢包包壁浇注料具有与原钢包包壁浇注料使用寿命相当的特点，这样不仅降低企业制造成本，而且通过对废弃物再利用相应地解决了白刚玉企业环保问题，同时也能降低铝矾土矿不可再生资料的消耗。
