Description

1.              Principle

Vacuum induction furnace is a melting equipment which is using intermediate frequency to inductive heat. A spiral tube coil is inside chamber. When connected with intermediate frequency current, there will be alternating magnetic field. Magnetic induction line will be cut by metal specimen, then create circulating current.

Circulating current will work on surface of metal specimen and make high current density on surface of specimen, then creates concentrated and strong hot effect to heat and melt metal specimen.

 

2.           Function

With ability to strictly control alloy contents, electromagnetical stir and degass in high vacuum, it is widely used in metallurgical production and material research department.

This furnace can be used in melting and casting Nickel, Iron, Cobalt and other high level precision alloy or high

purity metal under high vacuum or atmosphere protection environment.

By using graphite crucible or other kind of crucibles, it can indirectly melt low resistivity metal and alloy, such as gold, silver, copper, aluminum, bronze.

3. Specification
4. StructureIt is comprised with furnace body, furnace cover, alloy feeder, induction coil, coaxial electrodel, vacuum system, crucible, ingot mold, vacuum measuring system, water-cooling system, control system, etc


A. Furnace body: double shell structure, SS304 material, well polished surface, which are smoothy and good to shorten vacuuming time, and easy to clean. Reserved vacuum connection port, coaxial electrodel and power connection port.

B. Furnace cover : double shell structure with water cooling function, SS304 material, well polished surface, there are cooling water between two shell.

There are observe windows, alloy feeder, handle. Observe windows are convenient to observe experiment process. Totally 4 pcs , if one of them polutted or broken, it’s easy to switch and replace.

C. Alloy feeder:Convenient to fill in all kinds of material during melting process.

There are 5 parts of alloy feeder with covers for sealing. Before vacuumizing, put required material in feeder in advance. It can be used in vacuum situation, fill in material in order. Convenient to operate.

D. Induction coilL: enwinding by square copper, surface is painted for insulation, and fixed on insulationg board. With nuts to connect induction coil and coaxial electrodel, which is convenient to install, it can realize well elecric conduction and reliable vacuum seal.

Crucible is place inside of coil, there are glass wool cloth or asbestos board between coil and crucible, it can protect coil, prevent short circuit because of leakge of specimen. At the same time, prevent coil from thermal radiation of crucible.

There are refractory board in bottom of coil, it’s used to support crucible.

The number of coil is not stable, it differs according to different requirement.


E. Coaxial electrodel: conductive device. It can conduct electricity and make water flow. Through vacuum furnace body, convert current and cooling water to induction coil.

Vacuum rubber sealed coaxial electrodel in vacuum furnace body, rotate coil, crucible and specimen together.

Handwheel on out side can make furnace to original position.

F. Crucible: in order to prevent chemical reaction between specimen and crucible, different specimen is with different crucible.

G. Vacuum system: oil diffusion pump, mechanical pump to make sure vacuum requirement

H. Vacuum measurement:

Compound vacuum meter show vacuum degree from 13-13×10-2Pa and 13×10-2Pa-13×10-6Pa. Another pressure gauge range from 0.1MPa~133Pa

I. Gas inlet device:used for take in required gases, such as Ar, N2, Max. pressure:≤0.02Mpa.

J. Water cooling system

Water cooling system is connected with control system, when water pressure is lower, audible and visual alarm will on and turn off heating power which assure safety operation.

K. IGBT intermedia frequency power: high effeciency and energy-saving.

L. Control system:

PLC control with famous brand meter, intuitive interface, easy to operate.

Power supply: manual or automatical, all operations could make on touch screen, with wrong operation alarm function.

Temperature control system: full automatic PLC and touch screen control. Experiment data and result will be saved automatically, and create history curve. PLC controller, PID and over-heat alarm.

Control system software: Easy to operate and real-time monitor inside experiment inside chamber.
