摘　　要：分析了影响电渣焊焊缝质量的因素:焊接电压、电流密度、渣池深度、焊丝送进速度、熔嘴与阴极钢棒两侧之间的距离等,优化了相应的工艺参数,焊接实践表明:启动6个月炉底压降平均值降低15.4 mV、平均工作电压降低0.09 mV,外观质量有较大改观。The following influence factors for the quality of electroslag welding seam are analyzed,welding voltage,current density,slag bath depth,feeding speed of welding stick,the distance between the consumable nozzle and both sides of the steel rod,then the corresponding process parameters were optimized,the welding practices show:the average pressure drop of the furnace bottom decreased by 15.4 mV after start-up for 6 months,the average working voltage decreased by 0.09 mV,the appearance quality has great improvement.
