BLAST SMELTING CONTROL SYSTEM Russian patent published in 2003 - IPC

FIELD: ferrous metallurgy. SUBSTANCE: blast smelting control system has burden feeding subsystem, blast furnace subsystem, air heating unit subsystem. Said subsystems comprise functional control members and are united through complex of measuring facilities and through complex of technical controlling facilities. Control system has shop subsystem with first automated operators' positions and combined production subsystem with second operators' positions. Complex of measuring facilities is equipped with third operators' positions. First information inputs of measuring facility complex are connected to outputs of functional control members of burden feeding subsystem, subsystems of blast furnace and air heating unit, third outputs are connected to first informational inputs of subsystem of complex of technical controlling facilities. First outputs of subsystem of complex of technical controlling facilities are connected with first informational inputs of shop subsystem. First outputs of shop subsystem are connected with third informational inputs of combined production subsystem. Third outputs of combined production subsystem are connected to third informational inputs of complex of measuring facilities. First outputs of complex of measuring facilities are connected to control inputs of complex of technical controlling facilities. Outputs of complex of technical controlling facilities are connected to control inputs of functional control members of burden feeding subsystem, blast furnace subsystem and air heating unit subsystem. Informational inputs and outputs of first, second and third automated operators' positions are connected with second outputs and with second informational inputs of shop subsystem, subsystem of united complex of measuring and technical controlling facilities, respectively. EFFECT: increased efficiency in reconstructing blast furnace for complex automation and optimization of blast smelting process and improved technical and economic characteristics of blast furnace. 2 dwg
