Design Of Control System Of The Hot Billet Marking Machine

In order to facilitate the implementation of production management and qualitytracking of billet,when we found quality problems in product testing,it can be tracedback to a problem with the link in a timely manner,and Generally typically uniformthe number of billet. At present,Compared with foreign billet number automaticspraying equipment,Domestic development of automatic spray machine can not bewell adapted to the requirements of the iron and steel enterprises to controlperformance.Therefore, the enterprise needs to develop a new injection machinecontrol system of economical and practical,simple structure,stable function,accordwith modern steel billet production enterprises.This paper analysis the present situation of domestic and international researchmachine hot steel rolling, the iron and steel enterprises, combined with the technicalrequirement for the marking equipment, developed a novel hot steel rolling machinecontrol system of water-based heat resistant coatings.In this paper，fistly，elaboratedthe research background and the current research status of both at home and abroad onbillet, spraying equipment,put forward the problems existing in the domestic markspraying equipment,then according to technical indicators and technical process ofbillet spray equipment,Design of the overall design scheme of control system of hotsteel rolling machine.The actual demand of jet printing character combination of ironand steel enterprises, Siemens S7-Technology technological functions of the systemmatrix expansion design, at the same time on the design and implementation processof the matrix was analyzed. By the analysis of the hot billet spray Unit kinematiccontrol, and to build a Simulink simulation model of the servo control system, andSpray word agencies as a background to the servo system analysis. In this paper, thedesign of the servo system use of simulation analysis verified spray word agencies tomeet the control requirements of the position accuracy. Finally, the WinCCconfiguration software and integrated technological functions of the STEP7softwaresystem PC monitoring program and lower machine PLC control program design.Finally completed the design of the control system of the hot steel rolling machine,full automatic control is realized in the marking process.Through the practical application of the field devices that The design of the hotsteel rolling machine control system fully meets the iron and steel enterprises tocontrol system automation, intelligent requirements,has the stability,reliability andhigh ratio of performance to price, in the domestic market to promote the applicationof great value.
