    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 isget price

    Steel Pipe Manufacturing Processes mandrel mill process

    The advent of rolling mill technology and its development during the first half of the nineteenth century also heralded in the industrial manufacture of tube and pipe. Initially, rolled strips of sheet were formed into a circular cross section by funnel arrangements or rolls, and then butt or lap welded in the same heat (forge welding process).get price

    Don’t get flattened by the wrong plate roll

    Oct 07, 2013 As on four-roll machines, material loads parallel to the floor, so the machine pit can be constructed to working level. By design, the upper roll can be used as a traditional press. Side rolls can move close under the top roll, so that thinner plate bending can be done on smaller diameters.get price

    Strip Thickness Control of Cold Rolling Mill with Roll

    trolling the roll gap position is such that produces the desired output thickness [6]. Roll eccentricities are caused by axial deviations between the roll barrel and the roll necks due to irregularities in the mill rolls and/or roll bearings [11]. These irregularities cause cyclic deviations in the strip thickness at the output of a mill standget price
