The intermediate frequency furnace used for smelting is a power supply device that converts 50HZ AC power into intermediate frequency (generally above 300Hz to 1000Hz, also known as 150-10000Hz). It has the following significant characteristics:
1、 Efficient and energy-saving
Fast heating and short melting cycle: The medium frequency furnace uses the principle of electromagnetic induction to heat the furnace material, with high thermal efficiency and fast melting speed.
Energy saving: Compared to traditional smelting equipment, medium frequency furnaces have lower power consumption and significant energy-saving effects under the same output.
2、 Environmentally friendly and clean
Pollution free heating process: There are no large amounts of flames and gas emissions during the heating process of the medium frequency furnace, reducing investment in environmental protection equipment and minimizing environmental pollution.
Superior working environment: Workers are no longer exposed to the baking and smoking of coal stoves, improving their working environment.
3、 Easy to control
Variable frequency equipment is compact and lightweight: With the development of electronic technology, variable frequency equipment has become smaller, lighter, and easier to control.
Precise control of the smelting process: The intermediate frequency furnace can easily adjust the power, achieving automation and precise control of the smelting process.
4、 Strong adaptability
Convenient replacement of melting materials: The medium frequency furnace is convenient for changing the type of metal materials melted, especially suitable for small batch and multi variety casting units.
Adapting to various smelting needs: Medium frequency furnaces are widely used for smelting non-ferrous and ferrous metals, with strong adaptability to furnace materials and suitable for intermittent operations.
5、 Other characteristics
Good heating quality: The medium frequency furnace heats evenly, with minimal temperature difference between the core and surface, which can improve product quality and pass rate.
Self stirring function: The medium frequency magnetic field has a magnetic stirring effect on the melted metal, which is beneficial for uniform composition and floating slag.
Small footprint: The medium frequency furnace has a small volume, light weight, is movable, occupies a small area, and improves space utilization.
