Induction melting

 

Type series of ISTOL induction melting equipments with crucible furnaces - rated melt capacity of ferrous metal from 40 kg up to 10 tons - is designed for melting, reheating, holding on temperature and metallurgical treatment of ferrous metals (steel and cast iron). Furnaces are power can be regulated ontinuously between 20 and 100 % of rated value. Usually the equipment consists of two furnaces altematively Ilterconnected with one feeding converter. This arrangement enables uninterrupted operation in the event of furnace rammed lining making or repair. Furnaces are interconnected with converter by special disconnecting switch with electric servomotor. Hydraulic drive for furnace tilting. Frequency converter, capacitor bank and furnaces are water-cooled. Cooling circuits are equipped with automatic checking of temperature and water passage.

Induction melting, holding and reheating frequency equipments are also manufactured in modifications for treatment of nonferrous metals, e.g. coppper, aluminium, zinc and their alloys; for special using - glass or precious metal melting etc.

Advantages of induction melting, holding and reheating equipments

*     high melting capacity

*     minimum requirements on attendance and controlling

*     long service life of furnace and accessories

*     high operating ability

*     minimum melting loss of alloying additives

*     high quality of  castings

*     high operating reliability

*     high hygienic conditions in melting plant

 

       Basic accessory of each equipment is a break-through watching device, which reduces risk in the event of melt penetration to furnace coil. This watching device is also signalling the dry-state of new rammed crucible, the earth short circuit of power circuit and it prevents formation of a melt-to-earth potential. As optional accessories of equipment are delivered an automatic programmer for control of furnace operation, weighing device, device for rise of temperature of new rammed crucibles, etc.
