The furnace has vertical type and horizontal type. It is composed of furnace body, vacuum system, controlled silicon frequency-conversion power, control system, work platform, furnace lid and drive system, water cooling system, and others. Vacuum Induction Melting is the melting of metal via electromagnetic induction under vacuum. An induction furnace containing a refractory lined crucible surrounded by an induction coil is located inside a vacuum chamber. The induction furnace is connected to an AC power source at a frequency precisely matched to the furnace size and material being melted. Material is charged into the induction furnace under vacuum and power is applied to melt the charge. Additional charges are made to bring the liquid metal volume to the desired melt capacity.The molten metal is refined under vacuum and the chemistry adjusted until the precise melt chemistry is achieved. Impurities are removed by chemical reaction, dissociation, flotation and volatilization. When the desired melt chemistry is achieved, a preheated tundish is inserted through a valve isolated hot tundish insertion lock. This refractory tundish is positioned in front of the induction furnace and the molten metal is poured through the tundish, into the awaiting molds. 1) The technical design of ZG Vacuum Induction Melting furnace could be customized according to user’s special requirement. 2) Furnace design user’s friendly 3) High efficiency and low electric consumption 4) Special designed induction coil, surface insulated by special material to make sure no current flow during vacuum.
