What is coreless induction furnace?
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.
Which supply used for coreless induction heating furnace?
The coreless induction furnace can best be described as a refractory-lined vessel with an electrically energized/current-carrying, water-cooled copper coil surrounding it. Electrical current in the coil forms an electromagnetic field, which generates enough thermal energy to melt the charge.
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.
How does a furnace not melt?
Furnaces are typically built with a lining which is refractory – that is, it doesn’t readily melt at the temperatures within. But the lining does in fact ‘melt’ eventually. Linings are designed to be removed and replaced periodically.
How much electricity does a induction furnace use?
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 much electricity does furnace use?
A typical gas furnace usually requires a small amount of electricity to start and operate in your home. Most gas furnaces use less than 600 watts of electricity to run. So to run a gas furnace for 2 hours per day, will cost us around $0.156 with the average price of electricity in the U.S. that is 13 cents per kWh.
What is the difference between arc furnace and induction furnace?
Electric arc furnace uses electric arc generated by electrified electrode to melt metal and ore, while induction furnace uses electrified induction coil to heat and melt metal.
