Intermediate Frequency Coreless Induction Melting Furnace

Medium frequency coreless induction melting furnace (non-vacuum) adopts controllable silicon static medium frequency power supply for induction heating, which is used for smelting and thermal insulation of non-ferrous metals such as copper, aluminum and stainless steel. Generally, according to the capacity of the furnace body, it is divided into aluminum shell structure and steel shell structure. 

The aluminum shell structure generally adopts the tilting furnace mode powered by a reducer (there are also a few hydraulic tilting furnaces), and the steel shell structure generally adopts the tilting furnace mode powered by hydraulic pressure.

Use Environment and Conditions

1. Ambient temperature 2℃～35℃;

2. The relative humidity does not exceed 90%;

3. The altitude does not exceed 1000 meters;

4. There is no conductive dust and corrosive gas around;

5. There is no danger of explosion and violent vibration around;

6. The cooling water temperature is not less than 5℃ and not more than 35℃. The outlet water temperature is not more than 55℃, the pH value is within the range of 6 to 8.5, and the hardness is not more than 8 degrees (1 liter of water contains 10 mg Cao per degree);

 

7. Three-phase power supply voltage fluctuation is not more than 10%.

Main Technical Parameters

1. Power supply voltage: three-phase 380V

2. Power frequency 50Hz

3 if voltage 1000V

4 if frequency 1500hz

5. Working temperature: 1600 ℃

6. The inlet pressure of cooling water is 0.15 ~ 0.2MPa

Structure Description

The equipment is composed of furnace body, thyristor medium frequency power supply device (optional configuration: furnace tilting controller and cooling system)

1. The furnace body is composed of furnace shell, induction coil, furnace lining, Rzs reducer and other main parts. During smelting, the induction coil, water-cooled cable, capacitor cabinet and thyristor medium frequency power cabinet must be cooled with water. The furnace lining is close to the induction coil and is made of quartz sand. The tilting of the furnace body is directly driven by the tilting reduction box. The tilting reduction is a two-stage worm gear speed change, with good self-locking, stable and reliable rotation. In case of emergency power failure, the furnace can be tilted manually to avoid danger.

2. Intermediate Frequency Device

Thyristor medium frequency power supply is a device that changes three-phase power frequency into single-phase medium frequency to supply power required by the furnace. See the operation manual for circuit principle, operation and maintenance.
