The Design Of Computer Monitor And Control System For Gas-fired Reheating

Heating furnace is one of major equipment in Erzhong Group Company. It is heated the workpieces up to the temperature forging need. On the premise of fulfill quality and yield, it's demanded to reduce fuel consumption and billet oxidation burning loss. Of which key is the best dynamics decision temperature in real time.This topic research a DCS, superior computer carry on centralized management with manager and controller, manage, operate subordinate meter. Such as sending message to administer, setting craftwork curve to meter, self-regulation PID parameter of meter's program, follow up the scent of actual execution craftwork. Subordinate meter accomplish detection calculate and control with locale technological parameter etc. By the aid of researching the topic, technological transformation independent system optimization put in practice in combustible gas heating furnace technological transformation project.The topic analysis production fact and technological flow of heating furnace in ErZhong Group Company hydranlic machine plant, confirm hardware control scheme consociate with DCS control technology, use Kingview as configuration exploit soft, designed monitoring and controlling soft of automatic control system. The system can monitor and control locale fact monitor dynamically locale process data, save and consult history data, direct locale operation.Based on safe of locale controlling, system adopted two stage: first level is computer setting, used to normal activity state, computer achieve all control process; second level is man handle, used to toast or special activity state such as computer wrong. Communication scheme in this system, adopt RS485 bus mode.The monitoring and controlling system come on operation, running in good condition. The system had human-computer interface friendly, simple operate, graph table clarity, process data stabilization of monitoring and controlling menu, referring to history data any time, application value in practice production.
