How does a VIM furnace work?

Vacuum induction melting (VIM) utilizes electric currents to melt metal within a vacuum. Induction heating induces eddy currents within conductors. Eddy currents create heating effects to melt the metal. Vacuum induction melting has been used in both the aerospace and nuclear industries.

Can you melt metal in a vacuum?

The Vacuum Induction Melting Process As the name suggests, the process involves melting of a metal under vacuum conditions. Electromagnetic induction is used as the energy source for melting the metal. Induction melting works by inducing electrical eddy currents in the metal.

Can metals melt in a vacuum?

The Vacuum Induction Melting Process As the name suggests, the process involves melting of a metal under vacuum conditions. Electromagnetic induction is used as the energy source for melting the metal. The eddy currents heat and eventually melt the charge.

What is the cost of induction furnace?

What is the best price of Induction Melting Furnace per Piece?…Questions & Answers on Induction Melting Furnace.

Does melting point change in a vacuum?

All Answers (7) The melting point of a solid is very little affected by variation of pressure whether increased or decreased. Most polymers are solids so there is no need to worry; the recorded melting point is accepted under low vacuum (there will be no significant change from the normal melting point).

What is the main purpose of using a vacuum furnace?

The main purpose of using a vacuum furnace is for heating. During the heating process, a fast heating rate is required. The heating material selected must ensure good thermal conductivity, and it cannot produce deformation and a large amount of heat loss at high temperatures.

What is the function of an induction furnace?

An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. Induction furnace capacities range from less than one kilogram to one hundred tonnes, and are used to melt iron and steel, copper, aluminium, and precious metals .

What does vacuum furnace shell use commonly to cool down?

The vacuum furnace is usually made up of the input power supply system and the temperature control system of the vacuum system in the closed shell of the furnace. It is made of carbon steel or stainless steel for sealing the furnace shell. In order to prevent the deformation of furnace shell after heating and the heating metamorphosis of sealing material, the furnace shell is usually cooled by water or air cooling. The furnace is located in the sealed furnace shell.

Why does heat treat in a vacuum?

Vacuum heat treating is performed to alter the mechanical or chemical properties of a metal. In general, heat treating is meant to improve the metal’s properties , including increasing material strength, durability, hardness, corrosion resistance, and more.
