The invention discloses a refractory material suitable for a COREX furnace smelting reduction gasification furnace, and the refractory material comprises the following specific components: 70.29% of alumina, 20.32% of Cr2O3, 0.29% of iron oxide, and 4.06% of ZrO2. After a new process chrome corundum refractory material is adopted, the temperature of the vault of the gasification furnace is stabilized at 10-150 DEG C, the vault of the gasification furnace is safe and stable in operation, maintenance is reduced by 2 times, and the maintenance cost is reduced. And the maintenance cost of refractory material replacement is reduced by more than 30 million yuan. The method can meet the production requirements of similar enterprises, has obvious economic benefits and environmental benefits, and has high practical value and popularization significance.
本发明公开了一种适用于COREX炉熔融还原气化炉的耐火材料，耐火材料具体成份如下：氧化铝70.29%、Cr2O3 20.32%、氧化铁0.29%、ZrO2 4.06%，本发明采取新的工艺铬钢玉系耐材后，气化炉拱顶温度稳定在10‑150摄氏度，气化炉拱顶安全稳定运行降低检修2次，降低耐材更换的检修费用3000万元以上。可以适应于同类企业的生产要求，并具有明显的经济效益、环境效益，有较高的实用价值和推广意义。
