Electric induction melting furnace

An induction melting furnace is a tool for heating and melting metal by exposing the metal to an electromagnetic field. The pulses pass through the body of the raw material, exciting the heating of the charge by the principle of electromagnetic induction. Induction melting furnaces are widely used in mechanical engineering, foundry and metallurgy.

Induction melting furnaces and their equipment

A typical oven is an installation with the following components:

* Melting unit assembled

*Thyristor frequency converter or special transformer

*Capacitor battery

*Water cooled cable

*Hydroelectric station

*Heat exchange cabinet

*Control and alarm panel

*Remote control for furnace tilt

*Set of pipe tires

The melting units of the ITPE series furnaces are made of stainless non-magnetic steel. In addition to the furnace frame, the load-bearing elements are the lower and upper plates made of refractory concrete. An inductor is installed between the plates. The latter is directly connected to the capacitor bank and the current source. The charge is loaded into a crucible and smelted due to the electromagnetic field.

Advantages of crucible induction furnaces

Inductive heating has several advantages over resistance furnaces, gas burners, or solid fuel systems. Key features of induction furnaces are:

*Energy is supplied to the charge directly, bypassing intermediaries (the highest level of efficiency);

*The circulation of the molten metal guarantees the uniformity of the alloy;

*The minimum amount of waste, stable temperature in the crucible;

*The ability to arbitrarily set pressure and atmosphere;

*High level of output due to the regulation of the specific power of the inductor;

*Low weight of the lining and the ability to drain the metal “to zero”, which significantly reduces the inertia of heat;

*Relatively fast transition to different grades of metal in the process;

*Ease of operation and impressive possibilities for process modernization;

*Environment friendly (minimum waste from combustion products).

Manufacturing options for sets of induction melting furnaces

Several differences between furnaces:

*Melting process (air, inert gas, vacuum);

*Temporary organization (continuous, semi-continuous, periodicals);

*According to the crucible features – lined, graphite or metal water-cooled.

Induction melting furnace lining

Induction melting furnaces, which you can buy on our website, cannot do without lining (acidic, basic or neutral). Depending on the characteristics of the metals and the melting formula, the lining material is replaced to meet the necessary requirements:

*Acidic (quartz, dinas) for melting cast iron and carbon steel – withstand from 80 to 100 working cycles;

*Basic (magnesite, chromomagnesite) for melting low-carbon and chromium-containing steel – from 50 to 80 cycles;

*Neutral (spinel, corundum) for melting high-alloy and heat-resistant alloys – an extremely long working life.

*The composition of the lining mass has a great influence on the properties of the resulting products;

*Chemical purity of the alloy;

*Physical and mechanical properties of castings;

*Heat resistance and corrosion resistance of castings.
