Overview
The Medium Frequency (MF) Thyristor Melting Furnace is a device
that utilizes the principle of medium frequency induction heating
for metal smelting. Its core component is the thyristor-based
medium frequency power supply. This equipment boasts advantages
such as high heating efficiency, rapid melting speed, precise
temperature control, and ease of operation. It is widely used in
industries such as steel, non-ferrous metals, and foundries.
Working Principle
1. Medium Frequency Power Supply: Converts industrial frequency
alternating current (AC) into medium frequency AC, ranging from
several hundred to several thousand Hertz, through processes like
rectification, filtering, and inversion.
2. Induction Coil: The medium frequency AC passes through the
induction coil, generating an alternating magnetic field.
3. Metal Charge: The alternating magnetic field induces eddy
currents within the metal charge, causing it to heat up and melt.
Equipment Composition
1. Medium Frequency Power Supply Cabinet: Contains circuits for
rectification, filtering, inversion, and control, providing medium
frequency power to the induction coil.
2. Furnace Body: Includes the induction coil, furnace lining, and
furnace frame, used to contain the metal charge and facilitate the
melting process.
3. Capacitor bank: Adopts an internationally renowned brand with
quality assurance. Used for melting and heat preservation of
metals.
Cooling System: Cools the medium frequency power supply and
induction coil to ensure proper equipment operation.
4. Control System: Regulates the output power and frequency of the
medium frequency power supply, enabling automated control of the
melting process.
5. Water-cooled cable: Can be professionally customized according
to equipment requirements (cross-sectional area, length, connector
size, etc.).
