Ladle refining furnace

In recent years, secondary vacuum refining technique gets popular and further developed. The heart of global metallurgical industry has transferred from quantitative to be variety diversification and high quality. The super purity index ( total [H]、[N]、[O]、[S]、[P] get 50ppm,or even lower) reflects the quality of product, The effective way to achieve super purity index is secondary vacuum refining technique. There are many ways of secondary vacuum refining, the most popular ways are:
1, VD- ladle vacuum refining process.
2, VOD- vacuum oxygen decarburization ladle vacuum refining process.

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.
