Dynamic soft reduction technology can significantly improve the billet center segregation and loose , has become one of the advanced technology to improve bloom the . In this paper, the independent development Bloom dynamic secondary cooling and dynamic soft reduction process control system for research purposes . In the analysis of the course of development of the domestic and international dynamic soft reduction technology , application and research status on the basis of specific equipment features , combined with domestic factory bloom caster , research and development of a the Bloom dynamic secondary cooling and dynamic soft reduction process control system . The system officially put into operation in March 2008 application , the system is stable and reliable, full-featured , has produced 45 # YQ450 , 37Mn2 , LZ50 steel, meet the design requirements . The main progress achieved in this paper are as follows: ( 1 ) the Bloom dynamic secondary cooling and dynamic soft reduction process control overall system design and architecture . On the basis of the original casting machine control hierarchy structure , design and development of a the bloom dynamic secondary cooling and dynamic soft reduction process control system , its main components include the core process control module , system management module, communication module , the client and so on. (2) In the case of hardware harsh conditions , design architectures to improve the core process control model programming , implementation and design software monitoring module designed process control system , on the basis of stability in the function and operation of the guarantee system , to achieve the purpose of the system to run on an ordinary PC , to overcome the difficulties of poor conditions on-site hardware . (3 ) In order to facilitate the to achieve the karyotype process control model development and debugging , design and development of the off - line simulation system . Off-line simulation system full bloom steady and non- steady-state production process of casting conditions , on the one hand, for the development and debugging of the core process control model provides a good environment , greatly reducing the development cycle of the model , reducing the cost of commissioning , on the other hand , provides a powerful tool for process development and parameter optimization process engineers .
