Influence of Flotation Magnesia Particles and Al2O3 Fines on Properties of Periclase-spinel Bricks
文献摘要:
Periclase-spinel bricks were prepared using sintered magnesia,flotation magnesia,fused magnesium aluminate spinel and calcined Al2O3 fines as the starting materials and calcium lignosulfonate as the binder,mixing,shaping and firing at 1 650℃.Flotation magnesia particles were used to replace ordinary sintered magnesia particles and different amounts of calcined Ai203 fines were extra-added(0%,3%and 5%,by mass)to investigate their effects on the properties of periclase-spinel bricks.The results show that:the periclase-spinel bricks prepared with flotation magnesia particles have reduced apparent porosity and cold compressive strength,and enhanced bulk density,thermal shock resistance,hot strength and hot toughness.As the calcined Al2O3 fines addition increases,the apparent porosity and the cold compressive strength decrease,and the bulk density,the thermal shock resistance,the hot strength and the hot toughness are improved.
