Tundish seating brick prefabricated part and production method thereof
The invention relates to a tundish seating brick prefabricated part and a production method thereof, and belongs to the field of refractory materials. The tundish seating brick prefabricated part is prepared from, by mass, 50%-57% of corundum, 37%-42% of white corundum, 3%-8% of aluminum oxide micro powder, 0-4% of calcium aluminate cement and 1%-3% of silica fume. The tundish seating brick prefabricated part is prepared by taking the inked corundum, the white corundum, the alumina micro powder, the silica fume and the pure calcium aluminate cement as main raw materials. The obtained brick cup prefabricated part can greatly prolong the service life of the tundish brick cup, and has good thermal shock resistance and compression strength. Through industrial tests, the novel brick cup prefabricated part can completely meet the steelmaking molten steel treatment requirement, the fire resistance of the brick cup prefabricated part is greatly improved, the cost of the brick cup prefabricated part is reduced, the labor intensity of workers is reduced, and good economic benefits and social benefits are achieved.
本发明涉及一种中间包座砖预制件及其生产方法，属于耐火材料领域。所述中间包座砖预制件包括以下质量百分比的成分：50～57％墨钢玉、37～42％白刚玉、3～8％氧化铝微粉、0～4％铝酸钙水泥和1～3％硅灰。本发明采用墨钢玉、白刚玉、氧化铝微粉、硅灰和纯铝酸钙水泥作为主要原料制备中间包座砖预制件。所得座砖预制件可大幅度提高中间包座砖的使用寿命，具有良好的热震稳定性和耐压强度。通过工业试验，新型座砖预制件完全可满足炼钢钢水处理要求，大幅度提高座砖预制件的耐火性能，降低座砖预制件的成本，减少职工的劳动强度，具有良好的经济效益和社会效益。
