ABSTRACT

Model-intensive and web-based steel rolling mill applications have been developed in metalpass.com. They include pass design suites AutoForm and FreeForm, mill force/torque prediction suite, temperature profile program with finite-differential method for rolling and water/air cooling, and microstructure prediction application, etc. Coupled with tension models, the FreeForm is particularly useful for high-speed rolling blocks, and for both designing new passes and examining existing ones. Multiple algorithms are applied to ensure both speed and accuracy. Issues in developing each of the applications, such as process modeling, data modeling, model verification, object-oriented programming, and data management, etc., are discussed.
 

SUMMARY

Complicated rolling mill process demands sophisticated models and software; good future-potential awaits web-based mill application.

A variety of web-based programs, some powerful and others easy to use, are available online as great tools for advanced mill design and development.

Highly accurate models and extensive mill-tests verified the high quality of the web-based mill applications. Web-related handling further improved the performances of the programs.
