Ladle brick cup hot repairing material and preparation method thereof
The invention belongs to the technical field of steelmaking ladle refractory materials, and particularly relates to a ladle brick cup hot repairing material and a preparation method thereof. The ladlebrick cup hot repairing material is provided to solve the problems that a ventilation seat and a nozzle brick cup are prone to being corroded and damaged and the service life is shorter than that ofother ladle brick cups. The ladle brick cup hot repairing material is prepared from 39-43 wt% of carbon-free ladle brick particles, 19-23 wt% of fused alumina zirconia particles, 15-20 wt% of white corundum powder, 8-10 wt% of fine spinel powder, 8-10 wt% of alpha-alumina micro-powder, 0.5-1 wt% of silicon dust powder, 2-3 wt% of pure calcium aluminate cement, 0.1 wt% of a high-efficiency water reducing agent and 0.05-0.1 wt% of an explosion-proof fiber. The hot repairing material has the advantages of good self-flowing performance, excellent sintering performance, small linear change rate, good air permeability, certain medium and high temperature breaking strength and slag corrosion resistance, can effectively solve the phenomenon that the service life of the steel ladle brick cup blockis inconsistent with the service life of refractory materials at other parts and reduce the minor repair frequency and the labor intensity of workers, and has great practical significance.
本发明属于炼钢钢包耐材技术领域，具体涉及一种钢包座砖热态修补料及其制备方法。针对透气座与水口座砖易蚀损，使用寿命低于其余钢包座砖的问题，本发明提供了一种钢包座砖热态修补料，原料组成包括：按重量百分比计，无碳钢包砖颗粒39～43％、锆刚玉颗粒19～23％、白刚玉粉15～20％、尖晶石细粉8～10％、α三氧化二铝微粉8～10％、硅尘粉0.5～1％、纯铝酸钙水泥2～3％、高效减水剂0.1％、防爆纤维0.05～0.1％。本发明的热态修补料，具有自流性能好、烧结性能优越、线变化率小、透气性好等优势，同时具有一定的中、高温抗折强度，抗渣侵蚀性能，能有效解决钢包座砖与其他部位耐材寿命不一致的现象，减少小修次数、人工劳动强度，具有重要的现实意义。
