ChongQing Iron&Steel Works 4# Blast Furnace Computer Process Control System Design

Uses has DCS and PLC control function newest Simens PCS the S7 process control system, realizes the Chong QING Iron&Steel Works 4# blast furnace (volume is the 1350m3 non- material clock high pressure furnace top modernization blast furnace) the entire process control, specifically completes craft parameter the and so on the blast furnace, hot-blast stove, blast furnace feeding system and its attached craft system temperature, current capacity, pressure, material weight examination and the PID regulating control, as well as the process unit logical control, completes all process unit and the craft parameter monitoring, reports to the police, the data storage, the production report, data statistical analysis and so on function.This system included SIEMENS SIMATIC the NET ethernet, the operation has stood, the high reliable large capacity controller, uses the IM460/IM461 short range to expand, PROFIBUS the process field bus technology disperser I/O small steelyard system. The entire system operation station is the networking, the coordinated work. Regardless of is or looked from the production management system angle from the production control system angle, the overall system is a networking, the coordinated work big system. Advanced, the system revolution reliable, the data distribution reasonable, the operating speed quick, the man-machine contact surface is friendly, the easy to operate.The standard ether network (IEEE Ethernet 802.X), SIEMENS SIMATIC the NET industry ether network, the PROFIBUS process field bus (EN 50,170) constitutes three levels of networks system structures had guaranteed the system data communication redundant reliability, unimpededly fills with the high velocity (10M ~ 100M). The controller is the redundant reliability, large capacity S7-414, S7-416. The system each operation station is entire transparent, between them may realize mutually substitutes. The fault-tolerant optical fiber network application has guaranteed the network system data transmission anti- scene disturbance ability and the redundant reliabilityCompletes the blast furnace craft parameter the examination: foundation temperature, furnace bottom temperature, furnace stack temperature, top temperature; Blast furnace cooling system current capacity, pressure, temperature; Blast furnace blast system current capacity, pressure, temperature; The blast furnace rich oxygen and spurts the coal system the current capacity, the pressure, the temperature; Blast furnace coal...
