Abstract: An attempt has been made to develop a simulation model base for cold continuous rolling process so as to meet the requirements for investigating the controlling parameters in different models. Then the architecture and data structure of the simulation model base are worked out, including the object-oriented hierarchical/modular software system, and the simulation model base is thus formed and implemented by using the MATRIXx simulation platform and the reusable software for I/O dynamic linkage. To simplify the data processing during the simulative computation, the ODBC (open database connectivity) interface is programmed between the model base and database. With industrial data acquired, an analysis is made to some key problems in relation to models by applying the model base in rolling process, and the results reveal the practicality and advantages of the simulation model base as a model research and development platform.
