Power supply

Power supplies apply electrical power to induction coil. Electrical power from the mains converts to a high frequency sinusoidal current in the heating coil which generates an alternating magnetic field in the coil. This electromagnetic field induces a corresponding electrical current in each inductor in the vicinity of the coil. Power supplies made by Damavand…

Furnace

The heart of induction furnace, is the heating coil. This coil is a copper tube which is wound into a helical coil. This heavy duty tube has a hollow section made by high conductivity copper. There are shielding magnetic cores surrounding the coil. They act as a concentrator and prevents magnetic flux generated by the…

Hydraulic system

Hydraulic jacks tilt the furnace when ever molten metal is ready. High pressure hydraulic pump is required for hydraulic jacks. Operator can tilt each furnace with the aid of lever-type switches in the control panel. Different check lists are provided by manufacturer for operator to visit the hydraulic system periodically and make sure that there…

Cooling towers

Depending on the customer’s order, these cooling towers have structures made by fiberglass composites or galvanized iron. In spite of being more expensive, fiberglass composite structures have the advantage of being resistant to rusting and corrosion, unlike galvanized iron structures. These fans use counter flow cooling method. Unlike cross flow cooling towers, the direction of…

Pumping panel

Electro pumps which move the cooling water in the power supply and heating coil are placed in this panel. These pumps made by Italian company called “Lowara”. Water system is equipped with antifreeze system. This system prevents pipes from cracking due to freezing  in winter. There are several thermos switch and flow switches placed in…

Furnace select switch

  These circuit breakers are used to connect or disconnect power supply units to furnaces. In many cases it is needed to disconnect furnace from power supplies. For example when the refractory lining of the furnaces needs to be replaced, the corresponding furnace disconnects from the power supply and the other furnace connects to it.…
