110KW Low-Frequency Induction Melting Furnace 1-20KHz

Across International's IHL series 1 kHz to 20 kHz low frequency induction heaters are good for a wide range of applications including deep heat penetration for full hardening processes, steel rod forging, tempering of pressing dies, pre-heating for welding, and melting of metal batches over 4 lbs. They are not limited to ferromagnetic materials, so nonferrous metals can also be used effectively.

There are three major components to the system: the power supply, the compensating capacitor/transformer and the induction coil/smelting crucible. Our heaters automatically adjust to the best resonant frequency in order to achieve the most efficient overall heating results based on our customer's requirements which include heat penetration, heating efficiency, operating noise and electromagnetic homogeneity. Two of our most popular low frequency machines are the Melting Furnaces with Tile-Pour Melter and Auto-feeding Rod Heating Furnaces for Forging.

Safety Features

• Overvoltage protection: machine shuts down when input voltage is over 260V. Overvoltage light will turn on and buzzer will sound continuously. Alarm and light shut off automatically when voltage goes below 260V.
• Overheat protection: if sensor detects IGBT heat sink temperature is over 55⁰C, machine will shut down, overheat light will turn on and buzzer will sound continuously. Increase water pressure or lower water temperature until alarm goes off itself.

• Overcurrent/malfunction protections: machine will shut down, indicator light will turn on and buzzer wil sound continuously if one of these situations occurs:

  • One of the machine parts becomes overheated.
  • Interfering signal detected.
  • Short circuit between work pieces and induction coils
  • Machine failures.
  • Induction coils touching each other.
  • The input voltage is too low.
  • Low water pressure protection: if water pressure goes below 29 PSI.

Other Features

• Digital output, frequency and current displays
• Automatic and manual modes
• Comes with one graphite crucible. Additional crucibles available at extra cost
• ISO 9001:2008 registered manufacturer

IMPORTANT

• Always wear protective gear and goggles when operating the machine. Crucibles must be covered all the time during operation. Across International is not responsible for any injury or damage caused by misuse.
• Do not run no-load operation for a long period of time, it might cause damage to the machine.
• Circulating water must be pure, clean and below 45C.
• Machine must be grounded properly all the time during operation. 

Main Induction Furnace Specifications and melting Capacity:

The table below outlines the maximum melting capacity for each induction furnace model. Please note that each melting cycle takes approximately 50-60 minutes for a cold furnace and 20-30 minutes for a hot furnace.
