摘要
以高纯镁砂（8～5mm．5～3mm，3～1mm）和电熔镁砂（≤1mm）为骨料．电熔镁砂细粉、α-Al2O3微粉、亚白刚玉粉、镁铝尖晶石细粉及uf—SiO2微粉为基质，按骨料：细粉=70：30进行配制镁质浇注料。实验中用5％、10％、15％、20％的α-Al2O3与亚白刚玉粉组成的混合物取代等量的镁砂细粉，研究了添加物对镁质浇注料物理性能的影响。
High pure magnesia（8 - 5 mm,5 - 3 mm ,3 - 1 mm ） and electrofused magnesia（ ≤1 mm ） were used as aggregate, magnesia powder, α-Al2O3 breeze, sub while corundum powder, magnesia - alumine spinel powder and uf- SiO2 breeze were used asmatrix Magnesia - based castable was prepared with the weight ratio （aggregate ： fines） of 70 ： 30. In the experiment, 5 % , 10% , 15 % ,20% of the composition of α-Al2O3 breeze and sub - white corundum powder substituted respectively the corresponding contents of magnesia powder. The influence of the content of additions on the physical properties of the castable was studied in this paper.
