LHM-35AB Medium Frequency Induction Heating Machine

Constituent parts of medium frequency heating equipment:

Lihua medium frequency series induction heater adopts the parallel resonance circuit, according to different application situation, customer can choose direct output or MF transformer output, the basic structure and the composition has the following two types:

Medium frequency induction power + Compensation capacitor + induction coil

  • This structure is most common, such as medium frequency forging furnace, medium frequency melting furnace, etc. The equipment is simple, low consumption, high work efficiency, and low manufacturing cost.
  • The induction coil of this structure should be relatively long, winding by 3-10 meters copper tube.
  • The medium frequency induction power is direct output, the maximum voltage of induction coil is 550V, and is not isolated from the main power, so the induction coil must be well insulated and can not be directly exposed;

Medium frequency induction power + capacitor + transformer + induction coil

  • This structure is also commonly used, such as vacuum melting furnace, medium frequency quenching, etc. In this structure, different output voltage and induction coil current can be obtained by changing the ratio of intermediate frequency transformer, so as to meet the different requirements.
  • In this structure, the induction coil is separated from the main power, so the induction coil has good safety, low insulation requirements.
  • In this structure, due to the increasing of manufacturing cost of medium frequency transformer, the equipment cost is higher; and the medium frequency transformer dimension is larger, this also increases energy consumption.
  • Hot forging: the workpiece is heated to a certain temperature, and then the workpiece is forged into other shapes by punch, forging bed or other forms, for example: surface shell, table embryo, pull hand, mold accessories, kitchen tableware, crafts, standard parts, fasteners, mechanical parts processing, copper locks, rivets, steel brazing and other hot forgings;
  • Shrink fitting: it is mainly used between different kinds of metal or metal and non-metal. Through the heating of metal, the principle of thermal expansion or thermal fusion is used to connect the two materials, for example: the copper core of the computer radiators and the aluminum sheet, the embedded welding of the loudspeaker net, the composite of the steel plastic pipe, the sealing of the aluminum foil, the motor rotor, the sealing of the electric heat pipe, etc.;
  • Smelting: it turns the metal into liquid mainly through the heating of the metal. It applies to iron, steel, copper, aluminum, zinc and various precious metals such as gold, silver.
