EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

Despite continuous progress in roll development and improved rolling conditions, the control of work roll performances remains a major concern for the hot strip mill. One shortcoming is objective information and knowledge about the roll degradation and the origin. To address this situation, several hot rolling mills introduced a work roll evaluation procedure that is performed at the end of each rolling campaign. Most commonly a classification of the possible degradation occurrences is made with a severity index. To reduce the subjectivity of the roll evaluation, a procedure and guidance booklet was developed in the frame of a European project “Mastering Rolls”, (7215-PP/066). Now, more recently, this development has been taken a step further within the European project “Intellub” (RFSR-CT-2013-0003) where a tablet application was introduced to assist with the roll evaluation. The first implementation and testing of this new technology at the mill immediately showed the improvements and innovations that are possible with the introduction of this new tool.
