  • Vacuun furnace-Vacuum refining furnace-VD/VOD Vacuum Refining

    Application: VD-type vacuum refining furnace can conduct vacuum degassing for molten steel, alloy composition trimming and argon stirring in vacuum. VOD-type vacuum refining furnace carries out oxygen blowing and decarburization, vacuum degassing and alloy composition trimming in vacuum, mainly used for refining

  • Technology - SMI - Steel Market Intelligence

    Advanced steels for demanding and critical applications require vacuum melting in a VIM furnace followed by VAR or ESR remelting. Primary AOD's provide a better Cr yield than VOD's. Ladle Furnace (LF) This furnace is positioned between the melting and continuous casting facilities. It is used to exactly adjust the steel

  • VD / VOD - TENOVA

    It is normally used for deep decarburization of high alloy steel grades, usually to remove carbon without affecting chromium content in the production of stainless steel grades. The VOD unit can be operated as the sole decarburization unit after the furnace (DUPLEX process) or as a refining stage after rough decarburization

  • Stainless Steel Production: AOD and VOD.

    Dec 1, 2016 Switch to continuous in casting or in ingot moulds. VOD production (Vacuum-Oxygen-Decarburization). The melting of scrap practiced for VOD is the same as AOD. With the only variation of the liquid steel is poured into a ladle, entered into a plant (tank) capable of creating an initial 3 mbar vacuum and then

  • VD / VOD / Vacuum oxygen decarburization Furnace Manufacturers

    Huachang furnace is mainly engaged in EAF, LF, VOD/VD, SAF for the production of iron & steel, non-ferrous, ferroalloys, other special metals. From design, manufacturing, shipment to assemble, staff training, commissioning,the whole process can be carried out with HC-furnace.We are pleasured if there any chance we

  • Vacuum Oxygen Decarburization (VOD) - CVS Technologies

    The VOD plant is mainly used for the production of stainless steel. The plant is basically designed as a tank degassing plant which is additionally equipped with an oxygen blowing lance and other related equipment. Due to the reduced CO partial pressure under vacuum conditions, decarburisation of high-alloyed steel

  • Vacuum Oxygen Decarburization (VOD) - Engineering Dictionary

    While electric arc furnaces (EAF) are the conventional means of melting and refining stainless steel, VOD is an economical supplement, as operating time is reduced and temperatures are lower than in EAF steelmaking. Additionally, using VOD for refining stainless steel increases the availability of the EAF for melting
