Standard power consumption for steel induction furnace is 625 kWh/ton .
How much electricity does an 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 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.
What are the advantages of induction furnace?
Induction furnace capacities range from less than one kilogram to one hundred tonnes, and are used to melt iron and steel, copper, aluminum, and precious metals. The advantage of the induction furnace is a clean, energy-efficient and well-controllable melting process compared to most other means of metal melting .
How many watts does it take to melt an iron?
Power Consumption for the Electroheat Furnace for Cast Iron Melting Requires 550-575 kWh/ton .
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.
How do you reduce carbon in an induction furnace?
still several steps that can be taken to reduce oxidation: charge part of the high carbon metallics (pig iron or remelt scrap) first. These will melt faster and at a low temperature and form a high carbon «pool» (heel) in the bottom for the steel above to dissolve into. Then try to optimize the charge density .
What is the principle of induction furnace?
In the induction furnace, a coil carrying alternating electric current surrounds the container or chamber of metal . Eddy currents are induced in the metal (charge), the circulation of these currents producing extremely high temperatures for melting the metals and for making alloys of exact composition.
What are the application of induction furnace?
Induction furnaces can be used to melt custom castings or casting large bronze structures . They're built to provide the melting you need for most copper applications with low metal loss and precise temperature control.
How long does iron take to melt?
Therefore 48 minutes take for melting 1000 kg of cast Iron @ 700 kW. Power consumption is also depends on the manufacture of the furnace. Below is power consumption for the Electroheat furnace for different metals.
How many watts does it take to melt steel?
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 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.
Do furnaces use a lot of electricity?
A: A gas fired, forced air home furnace typically requires a small amount of electricity to ignite and operate in your home. Most gas heat furnaces use less than 600 watts of electricity, or less than half of a typical 15 amp electric circuit.
Is a gas furnace expensive to run?
In contrast to an electric furnace, gas models cost less to run . Natural gas is a much cheaper source of energy than electricity, and the cost per therm for natural gas has actually declined over the past few years.
