Environment-friendly castable for refractory prefabricated part and preparation method thereof
The invention discloses an environment-friendly castable for a refractory prefabricated part and a preparation method thereof, the environment-friendly castable for the refractory prefabricated part comprises a waste high-alumina refractory material, tabular corundum, white corundum fine powder, alumina micro powder, silica micro powder, pure calcium aluminate cement, heat-resistant steel fiber, an additive and an admixture. By adjusting the ratio of the raw materials, the environment-friendly castable is prepared through the procedures of impurity removal, crushing, iron removal treatment, screening, burdening and dry mixing. The environment-friendly castable is excellent in performance, can be applied to high-alumina refractory prefabricated products such as furnace top prefabricated parts of electric arc furnaces and furnace lids of refining furnaces, fully utilizes waste refractory materials, reduces the product cost, saves raw material resources, reduces the influence degree of the waste refractory materials on the environment, is simple in preparation process, and high in product yield.
本发明公开了一种耐火预制件用环保型浇注料及其制备方法，所述耐火预制件用环保浇注料包含废弃的高铝质耐火材料、板状刚玉、白刚玉细粉、氧化铝微粉、二氧化硅微粉、纯铝酸钙水泥、耐热钢纤维、添加剂和外加剂，通过调整上述原料配比，经过除杂、破碎、除铁处理、筛分、配料和干混工序制备环保型浇注料。本发明环保型浇注料性能优良，可以用于电弧炉的炉顶预制件和精炼炉的炉盖等高铝质耐火预制制品中，其充分利用废旧耐火材料，降低了产品成本，节约原料资源，同时也降低了废弃耐火材料对环境的影响程度，同时制备工艺简单，产品成品率高。
