VD/VOD ladle vacuum refining process strengthens blowing argon reasonably on the bottom of furnace; it can stir molten steel adequately and get ideal dynamics effect. If combining VD and LF, the furnace can get ideal molten steel refining temperature with easy structure and low cost. Both of the above process can dehydrogenize, denitrify, desulfurize, deoxidize under vacuum conditions and get the function of Vacuum Oxygen Decarburization (VOD) to achieve the purpose of refining super pure steel.
