Electric arc furnace - Wikipedia

An Electric Arc Furnace (EAF) is a furnace that heats charged material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one ton capacity up to about 400 ton units used for secondary steelmaking. Arc furnaces used in research laboratories and by dentists may have a capacity

Vacuum arc remelting - Wikipedia

Vacuum arc remelting (VAR) is a secondary melting process for production of metal ingots with elevated chemical and mechanical homogeneity for highly demanding applications. The VAR process has revolutionized the specialty traditional metallurgical techniques industry, and has made possible incredibly controlled

Vacuum Arc Melting - IITK

In vacuum arc melting the chamber is evacuated and then back filled with argon gas. Hence, melting is performed in argon atmosphere. Basic Principle: A standard Tungsten Inert Gas (TIG) welding unit is used as a power source. Heat generated by the electric arc struck between the electrode and the metals serves to melt

Vacuum Argon Furnace - Alibaba

Arc Furnace User Manual

ARC. To prevent exposure to yourself there is a welding shield which has to be be placed in front of the furnace. To prevent exposure to those around you there is a The arc furnace uses a pump to create a vacuum in the sample chamber. Figure 3: The control panel which controls the vacuum pump and argon flow.

Sample Arc Furnace SOP 9-2015.doc - Ames Laboratory

SOP Arc Furnace September 15, 2015. UNIT OPERATION SUMMARY SHEET[*] This equipment is operated after vacuum evacuation and backfill with High-Purity argon to give a clean, non-reactive atmosphere. Using an arc-welding power supply, an electrode at high potential is directed above the sample. The cooled

HHV Argon Arc Melting Furnace

A high vacuum of 1 x 10 -6 m.bar can be maintained within the furnace chamber. . The molten material is cast in a copper mould by suction, employing a vacuum pump. Provision is made for attachment to a vacuum pump for evacuation prior to back-filling with inert gas. Various sizes of copper moulds are used to cast rods
