| 摘 要： | 预熔渣是电渣重熔生产高质量和高端合金材料的必要造渣原料..实验研究了新渣料和预熔渣在湿 度90%大气下存放的增重率;新渣料中石灰含量对渣料吸潮性能的影响;新渣料和预熔渣对重熔过程钢中氢含量 的影响。应用结果表明，用电熔法制成预熔渣进行电渣重熔,吨钢电耗降低100 -200 kWh,钢锭成材率提高3%以 上，电渣锭无损探伤合格率大幅提高，显著降低钢中氢含量和改善钢锭表面质量。

| Abstract: | Premelted slag is a necessary flux addition for electroslag remelting process to produce high quality and superalloy materials.The weight gain rate of fresh and premelted slag in atmosphere with 90%relative humidity,the influence of lime content in fresh slag on moisture absorption performance of slag and the effect of fresh slag and premelted slag on hydrogen content in steel during electroslag remelting(ESR) process have been tested and studied.Application results show that as the premelted slag manufactu... |
