Cement-free ladle nozzle brick cup
The invention discloses a cement-free ladle nozzle brick cup which is prepared from the following raw materials in percentage by weight: 95 percent of magnesia and corundum raw materials, 4.5 percentof p-Al2O3 powder binding agent, 0.4 percent of water reducing agent and 0.1 percent of retarder. A cylindrical inner hole I, an inverted cone frustum body hole, a cylindrical inner hole II, a cone frustum body hole and a cylindrical inner hole III which are connected in sequence are formed in the brick cup body; a lower opening of the cylindrical inner hole III is positioned on the lower end surface of the brick cup; the size from the hole wall of the cylindrical inner hole I to the outer wall of the brick cup body is not less than 50mm, and the aperture ratio of the cylindrical inner hole Ito the cylindrical inner hole II is greater than 3: 1. Due to the design of the inner hole structure of the brick cup body, the slag resistance, the scouring resistance and the erosion resistance areimproved, the service life of the nozzle brick cup is prolonged by 35%, under the same smelting condition, the cement-free nozzle brick cup has excellent performance, high erosion resistance, low erosion rate and high ladle smelting frequency, the consumption of materials is reduced, and the yield and the economic benefit are improved.
本发明公开了一种无水泥钢包水口座砖，制备材料由以下重量比组成：95%镁砂和刚玉原料、4.5%p‑Al2O3粉结合剂、0.4%减水剂、0.1%缓凝剂，并给出了，在座砖上端面向座砖体内设置依次连接的圆柱体内孔I、倒圆锥台体孔、圆柱体内孔II、圆锥台体孔、圆柱体内孔III，圆柱体内孔III的下口位于座砖的下端面；圆柱体内孔I的孔壁至座砖体外壁的尺寸不小于50mm，圆柱体内孔I与圆柱体内孔II的孔径比大于3:1。本发明座砖体内孔结构的设计，提高了抗渣性、耐冲刷性、抗侵蚀性，水口座砖的寿命时间延长了35%，在相同的冶炼条件下，无水泥水口座砖表现处优异的性能，抗侵蚀性强、侵蚀速率低、钢包冶炼次数高、减少材料的消耗量，提高了产量和经济效益。
