What kind of furnace body structure to choose for induction melting furnace?

The furnace body of the induction melting furnace is composed of a furnace body frame, a fixed frame, a water and electricity introduction system, and a hydraulic system.

1. Furnace body:

The induction melting furnace frame adopts a frame structure, which has the advantages of simple structure, high strength, and easy installation and disassembly. It is equipped with magnetic yoke, inductor, furnace lining material and so on. The furnace body is tilted by sliding bearing seat and shaft. The tilting motion of the furnace body is driven by two plunger cylinders. It is operated by the multi-way reversing valve on the operating table. It can stay at any angle, and the limit rotation angle is 95°. The inductor is wound by a copper tube and consists of a working coil and a water-cooled coil. The water-cooled coil has the effect of equalizing the temperature of the side wall of the furnace lining and improving the life of the furnace lining. The strip-shaped yoke on the outside of the inductor is made of laminated silicon steel sheets to restrain the divergence of the magnetic lines of force and act as a tightening coil. Press bolts in the radial direction of the yoke. In this way, the inductor, the yoke, and the furnace frame form a solid whole.

2. Fixing frame:

The fixing frame of the induction melting furnace is a triangular frame structure, which is welded by section steel and plate, and the fixing frame is connected to the foundation through anchor bolts.

In addition to bearing all the static loads of the furnace, the fixed frame also needs to bear all the dynamic loads when the furnace rotates and the furnace lining is ejected.

3. Water and electricity introduction system:

The current of the inductor of the induction melting furnace is input through a water-cooled cable. There is cooling water in the copper tube of the sensor and the water-cooled cable. An electric contact pressure gauge is installed on the main water inlet pipe of the furnace to monitor the water pressure and alarm when the water pressure is too low; each water outlet branch of the induction coil is equipped with a water temperature temperature probe , Used for cooling water over-temperature alarm. The cooling water temperature rise is in accordance with GB10067.1-88: the inlet water temperature is less than 35°C, and the temperature rise is not more than 20°C.

4. Hydraulic system:

Two furnaces are equipped with a hydraulic station and an operating table. Used to control the tilting of the furnace body and the ejection of the furnace lining.

4.1. Hydraulic device:

The working medium of the hydraulic device of the induction melting furnace is anti-wear hydraulic oil, and its working principle is shown in the “hydraulic principle diagram”

4.2. Console:

The console is mainly composed of multi-way hand-controlled reversing valves, oil pump start and stop buttons, indicator lights and cabinets. Manipulating the valve handle can realize the tilting of the furnace body and the ejection of the furnace lining.
