1.Introduction Induction furnace is widely applicable in steel melting, steel casting, and other metal alloy melting. It is composed of furnace body, hydraulic system, water cooling cable and furnace body changing switch, electrical panels. We have induction melting furnace from 50kg to 70tons. 2.Working Principle The induction furnace uses the medium frequency power source to establish the medium frequency magnetic field, which causes the internal induction eddy current to achieve the purpose of melting materials. 3.Main features: 1).Solid steel structure and durable; 2). Good magnetic isolation, safe and reliable; 3). Solid frequency conversion power supply, easy operation; Adjustable power rate, Easy operation and maintenance 4). Easy to start up with load or free of load 5).Energy saving design type.
