Roll Pass Design – IspatGuru

Roll pass design is a set of methods for determining the dimensions, shape, number, and type of arrangement of rolling mill passes. Roll pass design also includes the calculation of pressing forces and their distribution on the roll passes. Several passes are made for each section; a square or round billet or bloom acquires a specified form on each successive pass. The roll passes are designed

Thumb rules in rolls pass design Fittings from oval to round must be 0.3 to 0.7. For ovals width to height ratio must be less than 3.0. 13. Spread When the steel is compressed in the rolls it will obviously move in the direction of least resistance, so usually there is not only longitudinal flow but also some lateral flow. This is called ‘Spread”. it is generally accepted that beyond a ratio width/height = 5, spread becomes

Extremely versatile, heavy section mills produce not only beams, but also channels, angles, shipbuilding sections, special sections, and sheet piles. Depending on your product range, we design your mill for the size spectrum you want. Typically, these mills produce web heights measuring up to 1,000 mm. Yet they can also handle 1,100 mm webs for super-heavy beams. Heavy section mills always come in the form of reversing mills.

Metal Rolling - Manufacturing

In shape rolling manufacture, a work piece will often experience different amounts of reduction in different areas of its cross section. One of the goals of roll pass design is to properly design a series of reductions in such a way as to mitigate the relative differences in shape change between areas, in order to avoid material defects. Improper reductions of the product can cause warping or cracking of the material.

Fig. 2.3 shows the successive stages in the reduction of a billet (100 x 100 mm) to a round bar. The billet is rotated at 90° after each pass. Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously
