摘要:

以白刚玉、板状刚玉、镁铝尖晶石、氧化铝微粉为原料,研究了不同尖晶石添加量对刚玉尖晶石砖性能的影响,通过对比试样的显气孔率、体积密度、常温耐压强度、高温抗折强度、抗热震性能和抗LF炉渣侵蚀性能,表明尖晶石添加量在10%~20%之间刚玉尖晶石砖的各项性能指标优良。

Abstract:

In this article,the impact of spinel additives amount on properties of corundum spinel brick is studied based on raw materials of white corundum, tabular corundum,spinel and alumina powder.By comparing the properties of the test samples, such as apparent porosity, bulk density,cold crushing strength,modulus of rapture under high temperature,thermal shock resistance and LF slag corrosion resistance,the result shows that all the properties of corundum spinel brick are excellent when the spinel additives remain between 10% to 20%.
