80 kg of aluminum is to be heated to a pouring temperature of 750°C. The unit melting and pouring energy of the metal = 1035 J/g. Thermal efficiency of the furnace = 65%. How much time is required to heat the metal from 25°C to the pouring temperature if the electric induction furnace generates 100 kW?
