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 ...

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.

Steel - Billets, bars, and rods | Britannica

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.
