Automatic Control System Of The No.2 SC In Pangang

PANGANG Iron and Steel CO. exits one set of double slab caster, but continuous casting rate is 50.6% and under metallurgy industry average , and its mould casting devices are established at the beginning of 1970s, the devices are old, consumed energy is high , severity pollution, low metal callback, quality is not stable, these restrict competition for market. For changing the phase, decide eliminate mould casting and establish continuous casting(No.2 slab caster, one strand).The writer is the principal of this project ! This text describes mainly the basic conditions,control desires of control system and . integrate the control system on basis of craftwork.On basis of the development of modern control technology and apply of the network technology and locale bus-mastering technology, the paper analyzes the essential element of slab caster system: casting speed ; expatiates in detail on the network structure and communication protocol of Ethernet and Profibus-DP ; mainly describes the forms of control system configuration,the function and features of its software and hardware designs ; also , introduces mainly control function of control system, for example,sequence control, tracking system and operation and monitor function etc. and analyzed and settled the problems of control system in debugging and producing .Success in addition of No.2 slab caster of the PANGANG Iron and Steel CO. have brought large economic and social benefits ! The succeed example design of automation are provided for the decision and popularization and implementation of add for old equipment. This project was conjoin of design and program and debug .The control effect of No.2 slab caster is satisfying , moreover ,achieve high speed and whole automatic aim.
