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°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.

熔铸Baddeleyite-刚玉质耐火材料的生产工艺特点

给出了提高连铸水钠钙刚玉耐火材料质量和经济效益的主要技术指标和因素。通过优化BC-33耐火材料的组成并观察质量比ZrO ₂：SiO ₂ = 2，可以生产出具有高耐腐蚀性，玻璃相析出温度高于1450°C且熔体中析出缺陷的趋势最小的材料。 1和SiO ₂：Na ₂ O≥12。仅当使用耐火材料的氧化熔融（包括炉料的电弧熔融和熔体的气-气处理）时，才能达到此类质量指标。
