| Message: | Usage:VD(vacuum degassing): in the condition of vacuum, [O],[H],[N] is removed with the condition what is the larger differential pressure. when the steel liquid is boiling with stirring by blowing argon, the [S] element is removed by what the slag was touched enough with liquid. VOD(vacuum Oxygen degassing): with the ability of VD , it got another ability that can reduce the element of carbon. VOD got a blowing oxygen device. when the steel liquid got the more oxygen by the blowing device , [c] element what is developing [CO] with Oxygen is removed. and another ability is what the steel liquid temperature will be kept by that [CO] is developed.
