1 - Introduction

Abstract

In this chapter, the topic of flat rolling of metals is introduced. The products of flat rolling, strips and plates, are defined in terms of their geometry; the ratio of their thickness to width is much less than unity. Strips are substantially thinner than plates. Rolling of strips and plates is generally referred to as flat rolling. The objectives of the process – that of reducing the thickness of the work piece, increasing its length and thereby changing its mechanical and metallurgical attributes – are stated in this introductory chapter. The temperatures at which the hot, warm and cold rolling processes are performed are defined. Each of the processes is presented and discussed in general terms. The equipment, the hot strip mill, mini-mills, Sendzimir mills, planetary mills and the cold rolling mill are shown and described, along with several mill configurations. The continuous casting process, as applied in the hot rolling industry, is also shown. New, recently developed equipment is described, as well. A selected list of books and publications, dealing with the theory of plasticity, plastic forming of metals and specifically the flat rolling process, is followed by some general conclusions.
