During center buckling, fibers at the center of the metal piece are longer than those at the edges. In an event where hot or cold mills have too much crown, mills roll out at the center. Sideways deflection of a structural member perfectly explains center buckling. Dealing with Center Buckling . Use crowned rolls is a solution to center buckling.

The work rolls in four-high strip mills and the rolls in two-high fine-section and wire mills are predominantly fitted with angular contact ball bearings as axial bearings (Figure 10). The chock arranged on the drive end is not axially located in the roll stand, but is guided on the roll neck by the axial bearing. Since the guidance forces are

The back up rolls act as a heat sink because there is a considerable amount of heat energy going into the strip and the work roll. Much of the heat in the work roll is transferred to the back up roll. Having a large diameter back up roll allows the mill to run at high rates of speed compared to an old 20-high mill.

Work roll surfaces for hot strip rolling suffer from consi-derable degradation due to high thermal shocks and addi-tional mechanical load. These shocks and loads produce plastic strain and residual stress. This necessarily leads to nucleation of cracks and forced hot strip mill to tem-porary shutdown, replace work roll or even to work roll

the material accelerates through the roll gap and becomes thinner. This is illustrated in Fig. 3. The heat is then transferred to the work rolls by conduction. In a hot mill, with product temperatures between 820°C/1500°F and 1100°C/2000°F, heat is also transferred to the work rolls in the area adjacent to the roll gap by radiation.

What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
