Energy conservation at high power consuming holding furnace with modified coil design and electrical circuits

This paper deals with high energy consuming induction holding furnace. The improved version of coil design along additional electrical interlocks and alarm, modified hydraulic controls, strengthening mechanical structures saving proposals at furnace fume extraction system ensures trouble free operation hence continuity production all the planned plant operational days. project involves in purchasing D-section copper extruded from Europe–Switzerland for its extended length existing 3 meters long to 9 Meters which enables reduction joints. performance has terms ofits consumption per ton liquid metal. payback period estimated investment will be less than 2 years.
