Vacuum Melting Furnace

Vacuum Melting Furnace Product Introduction：

Vacuum smelting furnace in vacuum conditions, the use of medium frequency induction heating principle, the metal melting complete set of vacuum smelting equipment, mainly for nickel-based alloys, precision alloys, high-temperature alloys, special steels, non-ferrous metals and their alloys in a vacuum or protective atmosphere for melting and casting.

Structure description of vacuum melting furnace：

1、Furnace body: double water sandwich structure, the inner wall of stainless steel (1Cr18Ni9Ti) materials, inner wall polishing, the outer wall of high-quality carbon steel and flange welded into a cylindrical structure, the flange plane open sealing groove, the use of "O" ring vacuum sealing and water-cooling devices (to prevent high temperature), air extraction holes, etc. "O" ring aging), pumping holes and so on. And set up steps for easy operation.

2, the furnace cover: the use of double-layer water sandwich head structure and flange welded into a whole, the inner wall of stainless steel (1Cr18Ni9Ti) materials, the inner wall polished, the outer wall of high-quality carbon steel water-cooling device, a rotating observation window, locking device, etc..

3, the bottom of the furnace: the same double-layer water sandwich head structure and the cylinder body welded into one, inside the casting platform or hole (casting long ingots) and set up water-cooling system, water-cooled ingot mould device, the bottom of the furnace wall welded with columns to support the furnace body and the furnace body coupling fixed.

4、Furnace frame: It is made of steel plate welded into cabinet frame structure, and the furnace body is placed on the frame.

5、Induction coil: made of high-quality rectangular copper tube winding inside the cooling water, external take-over coupling device.

6, water-cooled system: by a variety of valves, pipelines and other related devices and sound and light alarms automatically cut off the heating power supply.

7, intermediate frequency power supply: 100Kw KGPS silicon controlled intermediate frequency power supply, according to one tow two mode manufacturing reserved interface.

8, the main electrode and slewing bearing operating mechanism: from the electrode, curved electrodes, etc. and induction coil as a whole, through the handle operating mechanism to complete the casting process.

9, vacuum system: the three-stage pump configuration, by a 2X-70 rotary vane mechanical pump with solenoid valve (to prevent the vacuum pump oil due to a sudden power failure and back up), a ZJP-150 Roots pump, a TK-300 cavity diffusion pump with a cold trap (to prevent the oil vapour into the furnace chamber) ¢ 300 high vacuum butterfly valve, ¢ 80 manual butterfly valve, inflatable valves, deflating valves, the pumps and the vacuum pipeline connection with a metal Corrugated hose fast connection (to slow down the vibration), vacuum measurement by the composite vacuum gauge implementation.
