The analysis of two roll pass design options of ten roughing stands atOJSC "MMK" 370 rolling mill has been performed. The usage of a new form of the roll grooves will allow achieving higher durability of the rolls. Lesser rolls consumption will allow saving up to 800K rubles annually. More uniform load distribution by the stands will reduce the possibility of main mill lines equipment ...

Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.

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.

flow. So, the design of the roll groove geometry and the roll pass sequence are important aspect to be assessed. The pre-diction of the load and torque with different groove designs plays an important role in order to improve the draft during rolling. The roll grooves in a roller and the roll pass sequence in a hot rolling mill are usually ...

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in …

steel - steel - Billets, bars, and rods: Billets are the feedstock for long products of small cross section. In cases when they are not directly cast by a continuous caster, they are rolled from blooms by billet mills. One method of rolling billets, which are usually 75 to 125 millimetres square, is to use a three-high mill with box passes, as shown in A in the figure.

Pass design know-how. The shape of each roll pass sequence is specifically engineered to induce the right degree of reduction and keep an optimum, homogeneous deformation throughout the cross-section. For the latter purpose, it is common to use various shape transformations such as square-to-oval or oval-to-diamond.

A good maintenance program, as well as rebuilds or upgrades when necessary, is essential. 6. Mill in misalignment. Tube mill misalignment, poor mill condition, and inaccurate setup account for 95 percent of all problems in tube production. Most mills should be aligned at least once a year. 7. Tooling in poor condition.
