Induction Coreless Melting Furnace

Induction melting furnace – induction coreless melting furnaces mean to melt metal and get cast iron and steel casting of the highest quality, also for founding high-hardness and stainless alloys, ferroalloys. Induction furnaces use in the foundries of the metallurgical plant, in the precision casting shops and in the repair shops of the machine-building factories. ICMEF – are retrofit furnaces of IAC, ICIC, ISC. Induction melting furnace is suitable to melt non-ferrous metals and alloys, such as brass, bronze, aluminum, copper and others.

ARRANGEMENT OF THE INDUCTION FURNACE

Induction melting furnace in their design features comprises of main unit that means for melting and associated equipment. Melting unit represents a skeleton, which consists of two fabricated housings as well as hydraulic rams and central part of the induction block. Positioning group made from the sheet-rolling stainless steel.

The water-cooled induction heating coil manufactures from the copper pipe. Electric power and water supply on a coil carry out through the flexible leads. The necessary inclination (95 degrees) is provided by rams that impel by hydraulics. A supervisory control station in response to inclination is coincident with all furnace`s control panel and arranges at the operating area of the furnace.

The induction melting furnace operates on three-se alternating current 3*380 V from the shopfloor power rom an individual converter by usage thyristor frequency converter, which converts three-se current of industrial frequency to one-se current of high frequency. Control devices for monitoring operation of the converter placed on a front of the control panel. Frequency regulation while in operation carries out automatically. Control and s of a furnace cooling system and capacitors are placed on a cooling-water control unit.

MAIN ADVANTAGES OF THE INDUCTION MELTING FURNACE:

LTD “Termolit” produces equipment and employees the newest modern technologies. Equipment completes with reliable, quality parts and has manifold advantages, such as:

• High-quality component parts are used – German and Czech medium-frequency capacitors;
• Ecologically clean and quality materials are used, without usage of asbestos;
• Reliable thyristor frequency converters with automatic frequency trim during melting process;
• Higher melting power;
• Cylinder rods are defended against metal splashes;
• High reliability of furnaces operation;
• Safety of equipment while in operation;
• Inductance of induction coils and connective pacity of capacitor banks are optimized. As a result there are minimal losses in the furnace contour, as in:
• Higher output;
• Economically power consumption;
• Higher efficiency coefficient.

Coreless furnaces differ in design features, in size of the working chambers and in temperature range.
