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.

In the classic sense, a tube mill is a kind of welded roll form system; however, not every welded roll form system is a tube mill. Tube mills are welded roll form systems that have been fine-tuned to run a specific diameter range, typically at fast speeds (see Figure 1). Diameter range is mentioned because a tube mill welds a round product.

Roll Pass Design – IspatGuru

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.
