High-purity Fused Aluminium Magnesium Spinel
Aluminium magesium spinel has the characteristics of good thermal shock resistance,high temperature resistance,slag resistance,good appearance and good corossion resistance
Aluminium magnesium spinel is made of high-purity light burned magnesia and chemical Al2O3,smelted by electric arc furnace.It is widely used to make high performance refractory castable,slide gate nozzle,ladle brick roof of steel making electric furnace,converter,ladle,transitional zone of large cement rotary kiln,regenerative chamber of glass kiln and so on.
