  • Rolling (metalworking) Wikipedia

    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. If the temperature of the metal is above its recrystallization temperature, then the process is

  • About Rolling Conditions in Section Mills

    Abstract: The rolling conditions for heavy sections are very complied and may create different surface problems (uneven wear, fire cracks, sticking) in various areas of the passes. Additionally the roll pass design influences wear. Rolling loads – especially due to rolling accidents may cause breakages of the barrel or of collars.
