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.

Rolling Mill Rolls. 1. Definitions. Rolls are a tool to produce plastic deformation of the metal. It is an important consuming part to determine the efficiency and quality of the rolling mill. Roll is an important part of the rolling mill. The pressure generated by a pair or group of rolls is used to roll the steel.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

Rolled from heavy slabs supplied by a slabbing mill or continuous caster or sometimes rolled directly from an ingot, plates vary greatly in dimensions. The largest mills can roll plates 200 millimetres thick, 5 metres wide, and 35 metres long. These three dimensions are determined by the slab or ingot weight as well as the rolling-mill size.
TYPES OF CAMBER Natural mill camber is the out-of-straightness remaining after the initial rolling, cooling, and straightening of the member at the mill. Tolerances for natural mill camber are listed in the AISC Manual of Steel Construction.1 Induced camber is that which is applied subsequent to the initial rolling and straightening process.
