微粉和水泥用量对刚玉质浇注料性能的影响

Influences of microfine α-Al_2O_3 and cement additions on properties of corundum based castable

主要研究了活性α Al2 O3微粉和水泥加入量对刚玉质浇注料性能的影响。结果表明 :随着微粉用量增加 ,浇注料的流动性和抗渣性改善 ,凝结时间缩短 ,抗热震性降低 ;随着水泥用量增加 ,流动性降低 ,凝结时间缩短 ,高温处理后的常温抗折强度降低 ,抗折强度保持率增加 ,抗渣性恶化。

The influences of microfine α Al 2 O 3 and cement additions on properties of corundum based castable were investigated.The results show that with the increase of addition of microfine α Al 2 O 3 ,flowability and slag resistance of the castable improve,the thermal shock resistance becomes bad,setting time is shortened;with the increase of cement addition,flowability,CMOR and slag resistance of the castable become bad,the thermal shock resistance is good.
