Induction crucible furnace designed for melting and overheating of steel and cast iron. Possible melting of nonferrous metals (bronze, brass, aluminum) and their alloys in a graphite crucible. It is used in foundries, steel factories, workshops precision casting and repair shops engineering plants to produce steel castings of high quality. Induction heating – heating bodies in an electromagnetic field due to the heat of the vortex electric currents flowing through the heated body and excited in him due to the phenomenon of electromagnetic induction. When the current in the heated product is called induced or induced current. Induction units called electrothermal devices for induction heating or melting metals. Induction furnace, induction melting furnace – electrothermal equipment for melting materials with using induction heating.

Induction furnace operates on the principle of the transformer, whose primary winding is water-cooled coil, secondary, and at the same time load – located in the crucible of metal. Heating and melting of the metal takes place due to the currents flowing in it, which is caused by the electromagnetic field generated by the inductor. Electric consists of the smelting unit and equipment set. Melting unit is designed in a supporting frame consisting of two racks welded construction site "setting inductor" and the two hydraulic rams. Inductor consists of two sections, each of which a multiturn coil water-cooled, made of copper rectangular tube. Supply to the inductor power and water by using water-cooled flexible cables connected to it sequentially.

Hydraulic rams provide slope to drain metal furnace at an angle of 95 for 20 seconds. Managing tilt the furnace by an electric control valve, control panel, the slope of the furnace installed on site. Induction furnace is fed from the network through thyristor frequency converter TPCH, which is designed to convert three-phase industrial frequency AC high frequency. The main advantage of thyristor Electrically before is because of the lack of no-load losses reduced potreblaemaya power, increased efficiency, lower operating costs. Supply voltage converter comes from the transformer. Electric power is controlled by changing the voltage at the output of the converter and automatic frequency control in the smelting process. On front of the transducer placed controls, security alarm and control of the converter. In the control cabinet and authorities are signaling the remote control thyristor converter and control equipment and alarm systems. The cabinet mounted cooling water monitoring sensors and alarm systems cooling electric furnaces and condensers. Status of the lining of the crucible is monitored visually and by periodic measurements of the inner diameter of the crucible. Control over the work by using electric instruments and controls, located on the cabinet front panel controls and alarm systems. Main advantages of induction melting furnaces ITPE: In the manufacture of ovens used new clean and high quality materials, asbestos is not used. More robust components – Czech and German mid-capacitors. In furnaces used reliable thyristor frequency converters a new generation of automatic frequency control during melting. High power of fusion. Calculated and optimized selected inductance of inductors and trunk capacity of capacitor banks, the losses in the furnace circuit is minimized, resulting in achieved: higher productivity, greater efficiency in energy consumption, higher efficiency furnaces. In the production of electric current applied advanced technology. Rods of hydraulic cylinders are protected from the metal spray. Significantly increased and reliable operation of the furnace. Increased safety of operation of furnaces. In the design and manufacture of products focused on improving the effectiveness of protection equipment, and accordingly it standards of safety.
