Induction melting furnace power calculation formula P=(0.168×80×921)/(0.24×0.6×60)=1322KW where: 0.168—average specific heat of ferrous metal; 921—mass of molten metal (Kg); 100—melting The temperature rise of metal heating ℃; 0.24—heat equivalent; 0.6—average efficiency (in this example, 0.6, generally 0.5 to 0.65, 0.4 for special-shaped inductors are lower); 60—heating time (seconds) according to the above calculation, Can be equipped with a 0.5KHz induction melting furnace with a rated power of 1500KW。
