High-alumina ladle wall brick for steel ladle and preparation method thereof
The invention belongs to the technical field of ladle wall brick preparation, and in particular, relates to a high-alumina ladle wall brick for steel ladles and a preparation method thereof. The high-alumina ladle wall brick comprises the following raw materials in percentage by mass: 78% of calcium aluminotitanate, 10% of aluminum magnesium spinel, 7% of graphite, 3% of phenolic resin and 2% of aluminum powder, wherein the content of Al2O3 in the calcium aluminotitanate is greater than or equal to 80%, the content of Al2O3 in the aluminum magnesium spinel is greater than or equal to 60%, andthe content of C in graphite is greater than or equal to 95%. According to the invention, the waste residue-calcium aluminotitanate left in alloy production is used as an aggregate to replace an original traditional corundum-series refractory raw material, and the high-alumina steel ladle wall brick produced from the raw material not only reduces the cost, but also opens the market for recycling the industrial waste residue.
本发明属于包壁砖制备技术领域，具体涉及一种钢包用高铝质包壁砖及其制备方法，按质量百分比，包括如下原料：钛铝酸钙78％、铝镁尖晶石10％、石墨7％、酚醛树脂3％、铝粉2％，其中，钛铝酸钙中AlO的含量大于等于80％，铝镁尖晶石中AlO的含量大于等于60％，石墨中C含量大于等于95％。本发明利用合金生产所剩的废渣‑钛铝酸钙为骨料，替代原传统的刚玉系列耐火原料，用此原料生产的高铝质钢包包壁砖即降低了成本又为工业废渣的再利用打开了市场。
