An audit is a structured process to investigate the performance of a rolling mill or some other metal processing facility. Audits review equipment, automation and operating practices to determine how these impact on quality and productivity. Typical audit outcomes are: · a performance benchmark that establishes where the mill or facility stands with respect to industry best practice; · recommendations and a plan defining how to achieve the required performance improvements and · diagnosis of the cause of specific processing problems and solutions to rectify these. The paper describes the auditing process and several successful case studies on hot and cold steel rolling mills. Implementing the recommendations of these audits has resulted in significant improvements in yield, throughput, and quality.
