Metalworking And Casting

Electric heating prior to metalworking is well accepted in the forging and extrusion industries. It is readily adapted through preheating of steels, aluminum alloys and specialty metals such as titanium and nickel base alloys. The work pieces in this type of application consist of round, square or round cornered square bar stock. For steels, the high heating rates of electric heaters minimize scale and hence metal losses. The rapid heating boosts the production rates.
