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. Capacity 5-100t, purpose: vacuum ladle refining

Electric arc furnace uses electricity as fuel source and utilizes the arc high temperature produced by electrode and furnace charge to heat and melt the furnace charge. It is widely using in production of normal steel, high quality carbon steel, various alloy steel, stainless, various ferroalloys. It is the key equipment in steel making factories, foundry factories, ferrous alloys making factories and etc. 5-100 ton, transformer 2500-80000kva

Argon oxygen furnace is a kind of ladle refining furnace, which is characterized by side-blowing oxygen through the bottom tuyere with an immersion way. When the tuyere center is blown in with oxygen, argon and mixed gas of nitrogen, the proportion of argon and oxygen should be adjusted, then, it can achieve the purpose of decarburizing and retaining of chrome. Argon and nitrogen are used as cooling gas for tuyere ring to extend the life of tuyere. It can get the best operation by controlling the flow of the tuyere ring. And the flow of the tuyere center and tuyere ring can be controlled in master-control room.
