Computer-aided design of rolling mills

Abstract

Comput,rs have been used for design of rolling mills since 1960s. Easy access to high speed digital computers has facilitated use of more accurate rolling theories for design work and comprehensive computer simulations have been developed for all types of mills. These simulations include optimiTation of roll pass sequence, calculation of roll force, torque and temperature and detailed time studies for productivity calculations. These aspects of mill simulation are examined with specific examples. In the design of rolling mills equipment, computer-aided design has been widely used. The available software, which covers both steady state and dynamic analysis of items such as mill stands, drive systems, manipulators, cooling beds, roll cooling, and automatic gauge control systems, is reviewed with special reference to the nature of analysis and range of applications. Computer drafting is being increasingly used by rolling mills designers for both interactive and non-interactive applications. The integration of computer graphics with the design software holds promise for improving the productivity and creativity of designers and is an active area of development in rolling mills design organizations. A specific application where such integration has been achieved is discussed.

Computer-Aided Stress Analysis and Optimization of Rolling Mill Housing

“…Prager presented a method for the optimal design of a statically determinate or indeterminate truss [9]. Pandey developed computer simulations for rolling mills, which included optimization of roll pass sequence, calculation of roll force, torque, temperature and detailed time studies for productivity calculations [10]. Braibant focused on the use of optimization technique in the framework of CAD.…”
