A modern coreless induction furnace can melt a tonne of iron and raise the temperature of the liquid metal to 1450 °C using less than 600 kWh of electricity. Typically, specific energy consumption of coreless induction furnace varies from 500 to 800 kWh per tonne depending on type and grade of casting.

How is melt rate calculated in induction furnace?

Now 465 Tons divided by 25 working days gives 18.6 Tons of molten metal per day of 24 hours working. 18.6 Tons again divided by 24 hours gives required melt rate of molten metal is 775 kgs / Hour. So you should select 600kW & 1 Ton Induction Furnace, which will give you the suitable melt rate.

How can I reduce the power consumption of my induction furnace?

Another way to reduce energy consumption in the furnace is to pour at the coolest temperature that is practical and avoid temperature overshooting. For example, if metal that could have been poured at 2,750°F is allowed to rise less than 10% to 3,000°F, heat losses are boosted by 33%, using significantly more energy.

Can you melt aluminum with induction?

The induction melting furnace for aluminum is now used world-wide in the processing of aluminum products. The pure aluminum, being heavy, will sink and any impurities will rise, allowing them to take out from top using tilting mechanism, and leaving you with pure aluminum. Water cooling systems keep the coils cool.

What is the cost of induction furnace?

Questions & Answers on Induction Melting Furnace

How does a coreless induction furnace work?

The coreless induction furnace is essentially a refractory-lined vessel surrounded by an electrically energized, current-carrying, water-cooled copper coil. Electrical current in the coil forms an electromagnetic field, generating thermal energy that melts the charge. Slag formation is inevitable during melting.

What is induction furnace principle?

In an induction furnace, the metal charge material is melted or heated by current generated by an electromagnetic field. When the metal becomes molten, this field also causes the bath to move. This is called inductive stirring.

How much electricity does it take to melt steel?

Energy density To produce a ton of steel in an electric arc furnace requires approximately 400 kilowatt-hours (1.44 gigajoules) per short ton or about 440 kWh (1.6 GJ) per tonne; the theoretical minimum amount of energy required to melt a tonne of scrap steel is 300 kWh (1.09 GJ) (melting point 1,520 °C (2,768 °F)).

How much electricity does a furnace use?

We pay for electricity in kilowatt-hours (kwhs). One kilowatt-hour is the equivalent of using 1,000 watts for one hour or using a 100-watt light bulb for 10 hours….How much electricity does your appliances use?

How many watts does it take to melt aluminum?

Step 13: Performance Evaluation. When connected to 120 VAC this furnace produces about 350 Watts and takes about 2 hours to melt some aluminum and bring the temperature up to adequate pouring temperature.

How long does it take an electric melting furnace to melt aluminum?

The electric aluminum melting furnace adopt the Resistance wire as heating element ，the melting speed is low, usually it will takes about 4 hours to melt one batch, so most client will use the electric aluminum melting furnace to work togehter with the die casting machine, which can work as melting furnace & holding furnace.

How to calculate electricity cost for melting metal in induction?

Power Consumption for the Electroheat Furnace for Cast Iron Melting Requires 550-575 kWh/ton. SG Iron melting required 550-600 kWh/ton. MS/SS melting required 600-650 kWh/ton. Light scrap of Aluminum melting required 600-625 kWh/ton.

Are there any induction furnaces that can be me lted?

However, induction melting is of scrap that can be me lted. The inherent induction stirring provides excellent m etal homogeneity. Inductio n the less restrictive charge materials). A new generation of industrial induc tion melting furnaces has been developed during the last 25 years.

How is ch emistry of melt adjusted in induction furnace?

The ch emistry of melt was adjusted by adding mill scale, if opening carbon of bath was more. Good quality of steel melting scrap was used. In 1991-92, the Government license and control on steel m aking an d rolling was removed. Then more induction furnaces were installed all over India.
