摘要
The main technological indicators and factors for improving the quality and economic efficiency of fused-cast baddeleyite-corundum refractory production are given. Materials with high corrosion resistance, glass-phase precipitation temperatures above 1450 degrees C, and minimal tendency to precipitate defects in the molten mass could be produced by optimizing the BC-33 refractory composition while observing the mass ratios ZrO2 :SiO2 = 2:1 and SiO2 :Na2O >= 12. Such quality indicators are achieved only if oxidative melting of the refractories is used, including arc-melting of the charge and gas-air treatment of the melt.
