【Abstract】 7# furnace of Xuanhua steel is a medium-450M3 furnace, producing about 550,000 tons of pig iron. 7# furnace shafts of the Xuanhua steel, expected to contend for belts, expect middle, and then shipped to the furnace top of the zhuJuanyang hopper;Furnace top-expected bell furnace top to string cans. Automatic control systems used in industrial boiler distribution of Industrial it process control system (DCS). The control system is stable, reliable, low failure rate, advanced control ideas and modern communication technology and the latest developments in it technology concentration. Identity of temperature, pressure, flow into all computers. This presentation is being 7# furnace steel automatic system..
