Study And Application Of The Control System For 100-TON Converter Dry Gas Cleanning

On the basis of the thing that the doing type of abundant research purifies dust removal method , combine the environment of production scene of the converter, is it analyse and research to compare with synthetically , select WinCC/S7-400 series large-scale computer for use , surround with optic fibre ether network communication system solve converter produce the dust removal problem.Research and solve the problems of two respects mainly:Have adopted FB41 (continuous PID is regulated and controlled ) offered in STEP7 and realized the PID control of many return circuits. Adopted FC5 (sent the data functional block ) offered in STEP7, and FC6 ( received the data functional block) has realized doing the dust removal system of the law and news report of the converter noumenonn system, thus realized doing coordination and restriction that the dust removal system and noumenonn of the law smelt.Exploit the target, attribute, script procedure offered by WINCC , has worked out the picture of controlling, is it do law each that dust removal's operating need important to produce the parameter , control the operation of the production line at any time to show.
