提高电渣锭表面质量的控制措施

The controls on Improving the Facial Quality of Electroslag Ingot

通过合理调整工艺参数,如金属电极进入后的电流大小(6.5 kA)和保持时间(40 m in),冶炼时的电压和换电极时电流输入值等,使电渣重熔钢锭表面质量得到有效的提高。

By adjusting the technological parameter properly, such as, after the metal electrode＇s entering, the current value （6.5 kA） and the holding time （40 min）, the voltage when melting and the current input value when changing the metal electrode, etc. , thus improving the quality of the electroslag ingot.
