  • 60 YEARS OF ROLLING MILL TECHNOLOGY By American Steel

    When most people think of a rolling mill, they visualize sizable machinery in ferrous (iron, carbon steel and stainless steels) and non-ferrous (copper, brass, lead, etc.) integrated or electric arc furnace (EAF) steel mill of today, to small manually cranked rolling devices used at jewelers to reduce the thickness of the precious metal or impart a pattern on the surface of the metal to be

  • A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING

    Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll body and necks have to be considered as normal parts of designed components under high load. This means that necks should not experience

Figure 1 shows the tension and looper control in a typical finishing mill. Traditionally, looper angle control has been per-formed by changing the rotating speed of a main motor but there has been no tension feedback control because of the
