【摘要】 在不同条件下对 Li2 O降低保护渣熔点作用规律进行了实验研究 ,分析探讨其满足高速连铸保护渣熔化特性要求的配比及含量。实验表明 ,Li2 O是获得低熔点保护渣的理想助熔剂 ,其含量应在 2 %～ 5%范围内。更多还原

【Abstract】 In this paper,experiments were carried out for investigating action law of bringing down melting temperature.Constitute and content of high speed casting mold powders were discussed in view of melting property.Results show that Li 2O is ideal additive for lower melting temperature mold powders and it′s appropriate content is 2%～5%.更多还原
