Induction heating has replaced a wide variety of conventional process heating technologies, such as electric and gas furnaces, flame heating and specialized brazing processes. These methods heat the outer surface, while induction heating goes deep inside the workpiece. Energy cost savings of 20 to 50 are possible.
In one example, induction heaters replaced a salt bath and a gas-fired furnace for energy savings of 50 percent. Additional benefits included a 40 percent increase in process productivity and a 20 percent reduction in rejects. Another facility replaced their aluminizing process with an induction hardening system. The result was energy cost savings of 20 percent and productivity increase of 25 percent.
