The selection of the rolling mill pass system is an important part of the rolling mill pass design.. Whether it is appropriate to select have a decisive impact to the productivity and output of rolling mills, quality, consumption index, and production process operation, so the selection of rolling mill pass design system must be strictly carried out in accordance with specific conditions.

Before you can design the rolls, you must determine the proper number of passes and the rolling mill. After calculating the estimated strip width, you can develop the flower by using the arc and straight lengths. On a typical C channel, the return leg (bend No. 2) is the first forming to be done (see Figure 2). Some designers prefer to form ...

Produce a Bend Progression or "Flower.". Layout and design the Roll Forming Tooling around the flower. Incorporate fixtures, guides, side rolls, and straightening devices where applicable. After the crosssection has been finalized, and before the rolls can be designed, the proper number of passes and rolling mill must be determined.
The deformation behaviour of a hot rolled microalloyed steel bar of grade 38MnVS6 was examined using an FEM model during the initial passes in a blooming mill, as a function of three different pass schedules, roll groove depth, collar taper angle and corner radius. The simulations predicted the effective strain penetration, load, torque, fish tail billet end shapes, and metal flow behaviour ...
Hot rolling is among the most widely used manufacturing techniques. However, rolling mills are major resource consumers; thus, urgent rationalisation is required in the relevant industrial systems. Roll pass design (RPD) is a principal factor that determines process efficiency, product quality and resource consumption. Therefore, it is important to optimise RPD including the selection of roll ...
Aug 21, 2012. likes | Views. Rolling mill. Introduction to Rolling. Rolling is a bulk deformation process in which the thickness of the work is reduced by compressive forces exerted by two opposing rolls. The rolls rotate to pull and simultaneously squeeze the work between them. Introduction to Rolling.

In this work, a rolling simulation system for the hot rolling of steel is elaborated. The system is capable of simulating rolling of slabs and blooms, as well as round or square billets, in different symmetric or asymmetric forms in continuous, reversing, or combined rolling. Groove geometries are userdefined and an arbitrary number of rolling stands and distances between them may be used. A ...

The roll pass design proposal takes into consideration the lower plasticity of certain steels. Another special requirement was the shortest possible work length of the rolls. The standard odd number of passes was used because of the presumption that the roll pass design is a preparatory sequence of the laboratory rolling mill.

ANT has also designed passes for multislit rolling in various rolling ...
Rolling schematic view Rolling visualization. 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, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of is classified according to the temperature of the metal rolled.
