The future development direction of strip intelligent manufacturing is to realize the optimization of product quality and production process in multi- process, system- level and to improve product quality and production efficiency caused by the complexity of working interface and working conditions. In the construction of intelligent system, the following intelligent key technologies should be developed. First of all, based on CPS architecture, the precise control technology of process quality parameters and the structure of multi- process coordination optimization system should be developed. Secondly, intelligent optimization decision- making and dynamic scheduling technology should be designed for customized production to improve production efficiency. Then, with the online monitoring, diagnosis and optimization technology of product quality, the information flow of entire production process is fluent, the traceability of product quality anomalies is realized, and key quality parameters in the entire production process are optimized. Finally, with the development of the integrated intelligent control technology of rolling process, intelligent prediction of microstructure and performances, dynamic rapid design and steel grade merging technology could be realized based on temperature control- deformation coupling- performance matching control in rolling process.
