XinGang 11~#Blast Furnace Trough Below Feeding Control System Design And Implementation

This text tores down a 380m3 by XinGang company 3#?4#small blast Turmace,the foreigh land greatly fixs a 1050 m3 11#medium-sized blast furnaces(at first lately 8#blast furnaces)for study background.XinGang 11#blast furnace trough below feeding control system desigh and implementation.control system with operation safety stability,maintenance in brief convenience is desigh thought,adopted the reformation method that three electricity integral whole turns(EIC),namely the electricity control,gauge control and calculator carry on a conjunction through the 2 F correspondence network and stand in the operator of realization of HMI to production the spot of direct and control..Greatly fix according to 11#up anticipate the blast furnace slot of structure,and the PLC and network communication etc.industry to control technique at new steel company application within other blast furnaces,basic automation level of the Siemens company's S7-400 PLC and composition ET200M distributed measurement and control network.And using STEP7 V5.4 +CFC6.0 programming software for programming controller,drew up the next machine of 11#up anticipate to control procedure under the blast furnace solt,controlled system to carry out 11#up anticipate automatic completion to go together with to anticipate,compensate,provide to anticipate under the blast furnace slot,with time control leather belt up anticipate of whole processes,and satisfy an in proper order and allied lock control request.The place of honor machine supervision software takes InTouch10.0 SP2 as to develop tool and designed the supervision system of system appearance,and drew up homologous supervision procedure,carry out to the spot the reporting to the police of the returning back to file of the dynamic state surveillance function,history data function,excrescent signal of the process data function,the spot opetation of instruction function and to the control function of the production line etc,interface amity,be easy to an operation.From control system hurl luck,it are simple to circulate safety credibility,operation and maintenance,controlling the effect is good,improve the production ability and product quality of buseiness enterprise and lowered production cost and worker to labor strength.
