For metal heating and heat treatment, more and more manufacturers use medium frequency induction heating power supplies. According to people who have used it, this device not only has good heating quality, but is also very energy-saving.
1) Comparison of heating energy consumption of various fuels: Generally, the heating temperature of low alloy structural steel is 1200℃~1250℃. Among the heating consumption of various fuels, the lowest energy consumption is the medium frequency induction heating power supply, whose heating energy consumption per kilogram of billet is about 0.5 kW/h, that is, 0.202kg standard coal. Gas (calorific value 5650kJ/m3) consumes about 0.35kg standard coal for heating per kilogram of billet. Coal (calorific value 25120kJ/kg) consumes about 0.47kg standard coal for heating per kilogram of billet. .
2) Comparison of heating costs of various fuels: Calculated based on fuel prices in Henan (2002), to heat 1 ton of steel billet, the energy consumption of medium-frequency induction heating power is more economical, which is 123 yuan/t, followed by coal-fired heating, which is 145 yuan. /t, followed by gas furnace heating, which is 294 yuan/t, and finally oil furnace, which is as high as 401 yuan/t. According to my country's energy policy regulations, the use of oil as industrial energy is strictly controlled and should be phased out.
To sum up, using medium frequency induction heating power to heat steel billets is really very energy-saving compared with traditional coal-fired furnaces, gas furnaces, and oil-fired furnaces. If you don’t have such a device yet, what are you waiting for? Get one now.
