Abstract

Abstract: Ti burning loss rate during electroslag remelting(ESR)of alloy 0Cr15Ni25Ti2MoAlVB in a 2.5 t ESR furnace by 4 kinds of slag systems was tested and analyzed.The test results showed that as remelting using 75%CaF₂-15%Al₂O₃-10%CaO pure terary slag the Ti burning loss rate was 7.0%,lowest in 4 slag systems and free slag groove of ingot surface which occurred as remelting using 70%CaF₂-30%Al₂O₃ binary slag.

摘要： 试验分析了2.5 t电渣炉使用4种成分熔渣重熔0Cr15Ni25Ti2MoAlVB合金时的Ti烧损率。试验结果表明,4种渣系中75%CaF₂-15%Al₂O₃-10%CaO三元提纯渣的Ti烧损率最低,为7.0%,并且避免了70%CaF₂-30%Al₂O₃的二元渣系重熔钢锭表面渣沟等缺陷。
