Simulation research on energy saving control of reheating furnace

Energy source crisis and environment pollution are becoming more and more serious problems in the world recent years. During metallurgy industry manufacture process, a large proportion of energy is consumed by reheating furnace. How to reduce the energy consuming is a very important and valuable research subject. Based on 1580 reheating furnace in Baosteel, ACC and DCS two level control simulation system are build up. An optimized ACC setting model and DCS control algorithm were proposed in the paper. And the simulation results test by actual production data show that the new algorithms could save more than four percent energy compare with old ones.
