Abstract The effect of the amount of magnesium aluminate spinel powder (MASP) in lightweight periclase-spinel refractories on the cement clinker corrosion and adherence properties was investigated by the static crucible test and sandwich test. The results showed that MASP addition significantly affected the cement clinker corrosion resistance and adherence properties although it had little effect on the apparent porosity and pore size of refractories. The spinel in the refractories reacted with the cement clinker rather than periclase to generate the glass phase. Its amount and viscosity increased from 0 to 13 wt% MASP addition in refractories, which brought the benefit to the adherence strength. However, the excessive glass phase deteriorated the corrosion and penetration resistances of refractories as MASP was added up to 19 wt%. So, the addition amount from 9 to 13 wt% MASP into periclase-spinel refractories balanced the cement clinker resistance and adherence strength.

铝酸镁尖晶石粉含量对轻质方镁石-尖晶石耐火材料水泥熟料腐蚀及粘附性能的影响

摘要 通过静态坩埚试验和夹层试验研究了轻质方镁石-尖晶石耐火材料中铝酸镁尖晶石粉（MASP）用量对水泥熟料腐蚀和粘附性能的影响。结果表明，MASP的添加显着影响水泥熟料的耐蚀性和粘附性能，但对耐火材料的表观孔隙率和孔径影响不大。耐火材料中的尖晶石与水泥熟料而不是方镁石反应生成玻璃相。在耐火材料中，MASP 的添加量和粘度从 0 重量％增加到 13 重量％，从而有利于提高粘附强度。然而，当 MASP 添加到 19 wt% 时，过量的玻璃相会降低耐火材料的耐腐蚀性和耐渗透性。所以，
