Description
Induction Melting Furnace
An induction melting furnace is a power supply device that converts power frequency 50Hz alternating current into medium frequency (above 300Hz to 20kHz). It converts three-phase power frequency alternating current into direct current after rectification and then converts direct current into adjustable medium frequency current to supply medium frequency alternating current flowing through the capacitor and induction coil, generating high-density magnetic lines in the induction coil, and cutting the metal material contained in the induction ring, resulting in a large eddy current in the metal material.
An induction melting furnace is mainly used for melting carbon steel, alloy steel, and special steel, as well as copper, aluminum, and other non-ferrous metals. The induction furnace is light in weight and has high inefficiency. The medium frequency furnace is the main equipment in the casting, forging, and heat treatment workshop. Its working stability, reliability and safety are the guarantee for the normal and stable operation of the casting, forging, and heat treatment production line of flow operation.
1. Induction melting furnace includes:
KGPS IF power supply-Compensation capacitor cabinet-Aluminum shell furnace or steel shell furnace-Tilt furnace system-Remote control box, closed-loop cooling tower.
2. Induction furnace structure (steel shell furnace and aluminum shell furnace)
Aluminum shell furnace body; aluminum shell, induction coil, reducer
Steel shell furnace body includes steel shell furnace body, induction coil, and magnetic field shielding system.
3. KGPS intermediate frequency power supply
According to the power of the frequency conversion induction furnace, we can choose KGPS frequency conversion power supply, 12-pulse frequency power supply and 24-pulse frequency power supply, IGBT frequency conversion power supply. The control mode of IF power supply can be designed as local control, touch screen control, remote control and computer control.

Features
(1) High melting efficiency, good power-saving effect, compact structure and strong overload capacity.
(2) The temperature around the furnace is low, there is less smoke and dust, and the working environment is good.
(3) The operation process is simple and the smelting operation is reliable.
(4) The metal composition is uniform.
(5) The melting temperature rises quickly, the furnace temperature is easy to control and the production efficiency is high.
(6) The utility model has the advantages of a high utilization rate and convenient variety replacement.
(7) The long arc yoke shields magnetic leakage and reduces external magnetic resistance, has magnetic leakage at both ends of the shielding coil, and the inner side of the cross-section of the yoke is arc-shaped and seamlessly close to the outer wall, which increases the effective permeability area and enables the coil to obtain better support. The unique positive and negative rotation coil greatly improves the efficiency of the system.
