Based on the test results with a miniature preheater of 0.25ton capacity and measurements of temperature and volume of exhaust gas from a 25 ton electric arc furnace, a commercial scale scrap preheater was designed and installed to utilize exhaust gas from a 25 ton arc furnace. In the commercial operation of the installed preheater the following operation results were achieved after several improvements;
Item Reduction
Tap to tap time 8 min/heat
Power consumption 50kWh/ch·t
Electrode consumption 0.7kg/ch·t
Refractory consumption 17%
Production cost 670yen/ch·t
