Resistance Heating Machines
INTRODUCTION
The Electric Resistance Heating is the least expensive way to change electricity into heat in any metallic object. In a furnace, the entire furnace has to be heated, the elements have to be heated, which in-turn many times heat a muffle which in turn heats the part in which heat is desired. Resistance heating is a more direct method of producing heat only in the object in which heat is needed.
Applications
Just a few of the applications would be; wire drawing, extruding, warm or hot heading, brazing, forging, upsetting, roll parts, heat treating, heating strip stock for shearing, for forming, drawing and rolling, soldering and general purpose heating.
