Baking-free self-hardening tundish working lining repairing material and using method thereof
The invention relates to a baking-free self-hardening tundish working lining repairing material and a using method thereof, and the baking-free self-hardening tundish working lining repairing materialis composed of the following raw materials in parts by weight: 80-85 parts of MgO aggregate, 10-13 parts of binding agent, 3-5 parts of water and 3-4 parts of superfine silica-alumina powder. When the tundish is prepared, the MgO aggregate, the binding agent, the superfine silica-alumina powder and the water are stirred and mixed according to the proportion to prepare a working lining material, the space between a permanent lining of the tundish and a working lining mold is filled with the evenly-mixed working lining material, ramming and jolt ramming are conducted, standing is conducted for2-6 hours at the room temperature, and demolding is conducted. The repairing material does not need to be heated and baked, the turnover rate of the tundish can be effectively increased, energy is saved, and the operation cost is reduced.
本发明涉及一种免烘烤自硬型中间包工作衬修补料及其使用方法，免烘烤自硬型中间包工作衬修补料，按重量份由如下原料组成：MgO骨料80～85份、结合剂10～13份、水3～5份、超细硅铝粉3～4份。整备中间包时，将MgO骨料、结合剂、超细硅铝粉和水按照配比搅拌混合制成工作衬料，将混合均匀后的工作衬料填充到中间包的永久衬与工作衬模具之间，捣打震实，在室温下静置2～6小时脱模即可。本发明所述修补料不需要经过加热烘烤，可以有效提高中间包的周转率，节省能源，降低运行成本。
