|Abstract:||We present an audit of energy use at a steel mill in Singapore which produces wire rods and bars from scrap iron using the arc furnace process. The audit shows that the specific energy consumption is 1095 kWh/t of rolled steel. The electric arc furnaces and the reheat furnaces are the major energy consumers, having specific energy consumption of 502 and 342 kWh/t; their thermal efficiencies are 50 and 62%, respectively. Scrap preheating of the third charge, optimizing the reheat furnace production rates, and recovery of furnace waste heat to preheat fuel oil offer potential for substantial energy savings. © 1991.|
