Fire clay special for steel ladle corundum seating brick
The invention belongs to the technical field of refractory materials, and particularly relates to special fire clay for a steel ladle corundum seating brick, which is prepared from the following raw materials in percentage by mass: 80 to 90 percent of corundum raw material, 7 to 12 percent of silicon oxide mixture, 3 to 5 percent of zirconium oxide powder, 10 to 30 percent of gel material, 1 to 2 percent of nanometer aluminum oxide and 1 to 3 percent of water reducing agent. According to the invention, alpha-aluminum oxide, gamma-type aluminum oxide and nanometer aluminum oxide in the corundum raw material are arranged, so that impurities in the fire clay are reduced, the weight of the fire clay raw material is ensured, the success rate of preparing the steel ladle seating brick is better, and the phenomenon of cracking or direct cracking is avoided; according to the present invention, the raw materials in the fire clay can be well mixed, the fire clay can be well hardened in water, the strength can be maintained and continuously developed, the water reducing agent is arranged so as to reduce the water consumption during the fire clay use, and the fire resistance and the stability of the fire clay are improved under the combined action of the silicon oxide mixture and the zirconium oxide powder.
本发明属于耐火材料技术领域，尤其为：一种钢包刚玉座砖专用火泥，按质量百分比由以下原料组成：刚玉原料80‑90％、氧化硅混合物7‑12％、氧化锆粉3‑5％、凝胶材料10‑30％、纳米氧化铝1‑2％、减水剂1‑3％。本发明，通过刚玉原料中α－氧化铝、γ型氧化铝以及纳米氧化铝的设置，降低了火泥中的杂质，保证了火泥原料的重量，制备钢包座砖的成功率更好，不会出现裂缝或直接开裂的现象，通过凝胶材料的设置，能够使火泥中的原料很好的混合在一起，也能更好地在水中硬化，保持并继续发展其强度，通过减水剂的设置，在火泥使用时，能够减少水的使用量，在氧化硅混合物和氧化锆粉的共同作用下，提高了火泥的耐火性和稳定性。
