What is induction melting furnace?2023-04-19T18:10:02+08:00

An induction melting furnace is a machine that uses induction heating to melt various metals. It mainly includes an induction heating power supply and a furnace body (crucible) for holding metal. Under the action of the magnetic field of the induction coil, the metal located in the crucible is heated to the melting point until it melts into a liquid.

How efficient is an induction melting furnace?2023-04-19T18:11:47+08:00

It saves energy by 20%-30% compared with traditional melting furnace. Electromagnetic induction heating is a very energy-efficient way of melting metals, and it loses less capacity during the heating process.

What metals and materials can be melted in induction furnace?2023-04-19T18:12:42+08:00

Induction furnaces can melt nearly all conductive metals and materials. It mainly includes iron (cast iron and pig iron), steel, stainless steel, copper, brass, aluminum, gold, silver, platinum, zinc, tin, silicon and graphite. It can also provide energy through a conductive crucible to melt some non-conductive materials, such as glass and plastic.

What are the advantages of induction melting furnace?2023-04-19T18:14:47+08:00

Induction melting furnace has great advantages in metal melting, so it is preferred by various steel production enterprises.

  • Fast melting speed and high production efficiency
  • Low energy consumption reduces operating costs.
  • Induction heating less oxidation
  • Clean process
  • Safe and reliable
Can I use the same induction melting furnace to melt different metals?2023-04-19T18:16:26+08:00

You need to check with our engineers and technicians. Induction melting furnaces can melt a variety of metals, but the same induction melting furnace is more efficient when it is dedicated to melting the same metal. You can contact our engineers to optimize its design to melt many different metals. Due to the properties of different metals, you may need to use different refractories (crucibles) for different metals.

What cooling system is used for induction melting furnaces?2023-04-19T18:27:22+08:00

The induction melting furnace will generate a lot of heat when it is working. In order to ensure the normal operation of the machine, a cooling system is needed to reduce the temperature of the machine. Different types of induction melting furnaces can use different water cooling systems.

The main water cooling systems include:

  1. Simple water cooling system
  2. Open water cooling tower
  3. Closed cooling tower
  4. Industrial Chiller
How long is the warranty period of the induction melting system?2023-04-19T18:26:05+08:00

1 year. As long as you maintain and use it reasonably, you can use it almost forever.
