Equipment Introduction:

　　SG-FZP type non-vacuum induction melting furnace is a simple and efficient melting equipment, which usually uses resistance heating or induction heating to heat the material, so that the material reaches the melting point and maintains the melting state. Intermediate frequency power supply is a static frequency conversion device, using IGBT module to convert the power frequency three-phase AC power supply into a single-phase intermediate frequency power supply, so the efficiency is higher and the power factor is higher. The melting furnace is small in size, light in weight and movable, which can meet the melting needs of different materials.

Operating Principle:

The heating element of the non-vacuum induction melting furnace is a spiral tube induction coil installed on the rotating electrode in the furnace body. The alternating magnetic field is generated when the medium frequency current is input, so that the metal charge in the crucible in the coil is induced by the alternating magnetic field, so that a current in the furnace is induced in the direction opposite to the instantaneous current of the induction coil. Under the action of the skin effect, this eddy current is on the metal surface, forming a current layer with a large current density, thus producing a powerful thermal effect. Under the action of coke heat; The metal charge is heated until it melts and continues to heat up to meet the refining requirements.
