Abstract

As the hot rolling of steel moves into new more compact and effective processes, and as steel producers look for new ways to reduce their costs and increase their margins in ever tightening markets and tolerances, the evolution in Steckel mill technology, layouts, and new innovations may well keep the Steckel mill as a viable option, especially in areas of the world where minimized capital investments are required. In this paper we examine the evolution of the Steckel mills over the last two decades, with emphasis on new innovations and practical results, and provide a summary of hands on experience with some of these innovations. Also a focus on the South American Installations is given (from Siderperu to Gerdau’s newest Combination- Plate-Steckel-Mill). In addition, we aim to show the viability of the Steckel mill as an option for many existing or prospective steel producers, as the quality of the products rolled with Steckel mills reaches new quality parameters and as new innovations permit the rolling of thinner and wider materials, reaching new applications and wider share in markets, while maintaining a strong foothold in the traditional uses of Steckel mill products such as stainless steel, structural, and line pipe materials. As the ability to handle heavier, thicker, and wider coiled plate products increases, the coiled plate Steckel mills option is as strong an option as ever.
