Dry material for continuous casting tundish working lining
The invention discloses a dry material for a continuous casting tundish working lining, and relates to the technical field of metallurgical tundishes. The invention relates to a dry material for a continuous casting tundish working lining, which is prepared from the following raw materials in parts by weight: magnesia, ceramic powder, magnesium oxide, magnesium carbonate, aluminum oxide, a composite binding agent, an additive and mineral fiber, wherein the particle size of magnesia, ceramic powder, magnesium oxide, magnesium carbonate, and aluminum oxide is controlled to be 2-4mm, the composite binding agent comprises aluminum chloride micro powder, borax, an antioxidant, clay and calcium carbonate micro powder, and the mineral fibers comprise glass fibers, asbestos and crocidolite which are equal in mass proportion. By adding the mineral fibers step by step, a relatively compact fiber-containing layer can be formed inside and in a shallow layer in the forming process of the dry material of the tundish working lining, so that the cracking probability of the inside and the surface of the tundish working lining can be reduced when the tundish working lining is subjected to high-temperature operation, the heat resistance of the working lining is improved, and the service life of the working lining is prolonged.
本发明公开了一种连铸中间包工作衬的干式料，涉及冶金中间包技术领域。一种连铸中间包工作衬的干式料，包括由以下重量份的原料制成：镁砂、陶瓷粉、氧化镁、碳酸镁、氧化铝、复合结合剂、添加剂和矿物纤维，陶瓷粉、镁砂、氧化镁、碳酸镁和氧化铝均为粒径均在2‑4mm之间，复合结合剂包括氯化铝微粉、硼砂、抗氧化剂、黏土、碳酸钙微粉，矿物纤维包括等质量比例的玻璃纤维、石棉和青石棉。本发明通过分步加入的矿物纤维，能够在中间包工作衬的干式料的成型过程中在其内部和浅层形成较为紧密的含纤维层，从而能够在其进行高温作业时保证其内部和表面的开裂概率降低，提高工作衬的耐热性和延长其使用寿命。
