Melting Metal Induction Furnace
Description
Medium frequency IGBT melting metal induction furnace
Induction Melting Applicationsļ¼
Ā Ā Ā Ā Medium frequency melting metal induction furnace are mainly used for the melting of steel, stainless steel, copper, brass, silver, gold, andĀ Ā aluminium materials, etc.Ā Ā Melting capacity can be from 3KG to 2000KG.
Structure of the M. F. melting metal induction furnaceļ¼
Ā Ā Ā Ā The induction melting furnace set includes medium frequency generator, compensating capacitor and melting furnace, infrared temperature sensor and temperature controller can also be included if ordered.
Three types of melting furnaces can be ed according to the way of pouring out, They are tilting furnace, push-up furnace and stationary furnace.
According to the method of tilting, tilting furnace is divided into three kinds:Ā Ā manual tilting furnace, electrical tilting furnace and hydraulic tilting furnace.
Main features of M.F. melting furnacesļ¼
1. M.F. melting machines can be used for the melting of steel, stainless steel, brass, aluminium, gold, silver and so on.Because of the stirring effect which caused by the magnetic force, the melting pool can be stirred during the melting course to ease the floating of the flux and oxides to produce high quality casting parts.
2. Wide frequency range from 1KHZ to 20KHZ, working frequency can be designed by changing the coil and compensating capacitor according to the melting material, quantity, stirring effect desire, working noise, melting efficiency and other factors.
3. Power efficiency is 20% higher than the SCR medium frequency machines;
4. Small and light, a lot of models can be ed to melt different amount of metals. Not only is it suitable for the factory, but also suitable for the college and researching companies to use.
Main models and melting abilitiesļ¼
The table below lists the main models and recommended maximum melting abilities. About 50 to 60 minutes are needed to finish one melting process at cool status of the furnace, at hot status of the furnace, only 20 to 30 minutes are needed.

Compare with other equipment melting
1, VS resistance heated furnace
a, High heat efficiency ,melting fast.
b,Small size ,save energy 30%.
c, Resistance or silicon carbide stock easy to damage .
2, VS Coal ,Gas ,diesel furnace
a, Facilitate the adjustment solution composition and temperature ,the bubble of foundry less 1/3 to 1/4 ,reject rate down 1/2 to 2/3 ,so that cast have a higher mechanical strength;)
b, Reduced the oxidation of burning;
c, Induction melting can melt scrap of processing and the small pieces because of its electromagnetic stirring effect .reducing the cost of materials .Reduce environmental pollution ;noise is far below the towering equipment .Labor intensity of workers and working conditions have been improved;
d,Cast-iron crucible used in Coal and gas furnace is harmful to the aluminum alloy by increasing impurity. Graphite crucible used in induction melting without such disadvantages.)
3, VS SCR or Frequency Melting Furnace
a,High heat efficiency ,melting fast.
b,Small size ,save energy above 20%.
c,Electromagnetic stirring effect is slight so service life of crucible is extended.
d,By adjusting the frequency to achieve power regulation ,so melting speed fast ,material elements of burning loss less and better energy saving ,in particular the heating of stainless steel ,copper ,silicon ,aluminum and other non-magnetic material ,thus reducing the cost of the casting.
