Types of Induction Furnace

(1). There are core frequency melting furnace
     1. Secondary coil and the melting of the metal parts of the same
     2. Apply to copper, copper alloy, nickel, nickel alloy, aluminum, cast aluminum alloy
     3. Features: apply to high-volume continuous production, to large power
     4. Cast iron smelting furnace in the sky after the core frequency has poured into the furnace or heat insulation
     5. When the material can not be expected to be empty
(2). No-frequency melting furnace
1. When a material that can not be empty
(3). IF no melting furnace (the greater the stove, the lower the frequency)
1. Frequency furnace shortcomings: As the sensor, under both ends of the distribution of magnetic force lines at reduced, so in the crucible in the middle of large electromagnetic force, would damage the crucible and material, will be expected to block the bubble, intermediate frequency furnace can be overcome.
2. Frequency, frequency furnace to be equipped with capacitors, but the frequency furnace by the relatively small number of
(4). Conductive crucible furnace no (material: graphite, iron)
As graphite, iron resistivity high, so high-efficiency electric iron crucible for the general induction heating molten aluminum (at the surface heating, known as the skin effect)
One. Induction Hardening (surface hardening)
1. Characteristics: Surface hardness, good toughness of the Department of Heart 
    . Induction heat 
    . The characteristics of the electric induction
     1. As the skin effect on the surface can be quenched
     2. High power density, you can make melting furnace
     3. Issued by the heat from the workpiece, working conditions, environmental conditions
