• The objective of this paper is to build a shape decision and control system for the stainless steel and to ensure reducibility of workload for the next rolling process. The criterion of the shape quality is derived from the customer needs, and a shape decision system is implemented at the skin pass mill (SPM). The methods of shape decision are based on curve fitting and frequency analysis, and so on. A shape control system is also implemented with a programmable logic controller (PLC) using fuzzy logic. It receives process data from sensors such as shape meters, load cells, and pressure transducers. The field test with concerned customers is successful in the shape decision and control. The rate of the right decision is almost 99% and the claims from the customer have been largely reduced by annual 102 tons. The productivity of the rolling process is increased up to 38%.
