Abstract

A new hot strip mill has a lifetime of several decades. During this time the hot strip mill must be able to meet the market demands for a wide range of steel grades especially for high-strength steel and advanced steel grades with superior strip quality. And also during this time the hot strip mill will see good economic times, when availability and maximum productivity are most important, and bad economic times, when the reduction of operating cost and the development of new products and materials is the target. This paper is about ways to reduce operation costs and ways to implement technological features which allow new, more attractive market niches to be entered. Based on the extensive experience in the equipment and process modernization of hot strip mills, Siemens VAI has established a number of modernization packages which can reduce production cost and improve product quality performance. Examples of these modernization packages across the whole productions route are shown in this paper.
