Brief description of 0.25T induction melting furnace structure
The 0.25T induction melting furnace consists of a furnace body, a mechanical tilting device, an intermediate frequency power supply cabinet, a capacitor cabinet, a water-cooled cable, a water and electricity introduction system, and an operating cabinet (or a control button box).
Furnace body
The 0.25T induction melting furnace body consists of an aluminum furnace shell, an inductor and a lining material. The aluminum furnace shell has the advantages of simple structure, light weight, no need for magnetic boring, and convenient installation. The inductor is wound with a rectangular cross section copper tube, and the copper tube is cooled by water. The upper and lower ends of the inductor are fixed on the asbestos cement board through the column, and the outer side is supported by a radial bolt, so that the inductor and the furnace shell become a stable whole.
2. Tilting device
The 0.25T induction melting furnace has rotating shafts on both sides of the furnace and is mounted on the sliding bearing housing. One end of the rotating shaft is coupled with the output shaft of the reducer, and the reducer drives the furnace body to tilt. The tilting angle can be arbitrarily controlled, generally not more than 95 degrees. The reducer model is RZS-531A worm reducer, and the reducer motor power is 4Kw. Each furnace is equipped with a set of tilting device.
3. Hydropower introduction system
The current from the inductor is input through a water-cooled cable. Cooling water is supplied to both the inductor copper tube and the water-cooled cable. An electric contact pressure gauge is installed on the inlet branch of the inductor, and a bimetal thermometer is provided on the outlet branch for cooling water underpressure and over temperature alarm. The temperature rise of the cooling water is in accordance with the provisions of GB10067.1-88: the inlet water temperature is ≤35°C, and the temperature rise is ≤20°C.
4. Operation cabinet
The operation cabinet is mainly used for the operation of the tilting furnace control, and is equipped with a button for controlling the forward and reverse rotation of the motor. According to the user's requirements and the situation on the spot, it is also possible to carry out the operation of the tilting control by moving the button box.
