Behavior of Hydrogen during Electroslag Remelting Process

Article Preview

Behavior of hydrogen in steel during electroslag remelting process was investigated on a laboratory-scale unit. Results indicated that a considerable amount of hydrogen was picked up by the metal at the beginning of the process. Hydrogen content decreased with the increasing of ingot height. To avoid the hydrogen peak, anhydrous components must be used. Protective atmosphere combining with premelted slag was the optimal measure to control hydrogen in steel when the solid-starting technique was carried out. According to the results in the experiment it was not the crucial factor for hydrogen in steel remelted under protective atmosphere whether slag contained lime or not at actual remelting period.
