Induction Melting Furnace - Reduce Heat Loss by 30%

The environmental heat loss of the induction melting furnace is small. Environmental heat loss refers to the heat lost from the heat source to the surrounding environment in the form of convection, conduction, radiation, and latent heat during the heating process, including heat dissipation loss, radiant heat loss, heat storage loss, and exhaust heat loss.

Compared with the resistance heating furnace, the induction melting furnace is similar to the resistance furnace heat treatment in terms of heat loss and escape heat loss (the heat taken away by the furnace gas and cooling water) during the rapid heat treatment. However, it is much smaller than resistance furnace heat treatment in terms of heat storage loss and radiation heat loss. The main difference is that the ratio of the volume to weight of the inductor used in the induction melting furnace and the refractory material of the resistance furnace lining is too large, and the difference between the two is nearly a hundred times. A large amount of refractory materials are used in the masonry furnace body of resistance furnace and oil-fired furnace, which is the root cause of a large amount of heat storage loss. Nearly 30% of the heat is lost to the refractory materials used in the heating furnace, and the amount of refractory materials used in the induction melting furnace is very small.

In short, the environmental heat loss of induction melting furnace is small, which is beneficial to improve thermal efficiency and reduce unit energy consumption. The main heat loss during induction heating is the heat taken away by the cooling water, which only accounts for 10% to 15%.
