Preparation method of erosion-resistant steel ladle air brick
The invention discloses a preparation method of an erosion-resistant steel ladle air brick. The preparation method comprises the following steps: preparing 55-70 parts of microporous corundum particles, 5-20 parts of aluminum-magnesium spinel particles, 5-10 parts of activated aluminum oxide micro powder, 3-6 parts of pure calcium aluminate cement, 2-5 parts of magnesium oxide micro powder, 1-5 parts of chromium oxide micro powder, 0.03-0.06 part of organic fibers, 1-3 parts of a binding agent and 8-15 parts of water. According to the preparation method of the erosion-resistant steel ladle air brick, it can be guaranteed that the steel ladle air brick has high erosion resistance, high strength and good thermal shock resistance, the service life of the steel ladle air brick is effectively prolonged, the replacement frequency of the steel ladle air brick is shortened, the use cost is reduced, and the economical efficiency of smelting is improved.
本发明公开了一种耐侵蚀钢包透气砖的制备方法，包括准备微孔刚玉颗粒55～70份，铝镁尖晶石颗粒5～20份，活性氧化铝微粉5～10份，纯铝酸钙水泥3～6份，氧化镁微粉2～5份，氧化铬微粉1～5份，有机纤维0.03～0.06份，结合剂1～3份，水8～15份。该耐侵蚀钢包透气砖的制备方法能够保障钢包透气砖具有高耐侵蚀性，强度高，热震稳定性好，有效提高钢包透气砖的使用寿命，缩短钢包透气砖的更换频次，降低的使用成本，有利于提高冶炼的经济性。
