Rolling of bar,rod,and section: aluminium and aluminium alloy

Abstract

The development of the rolling of aluminium rod has been closely allied to the introduction of aluminium for electrical conductors, first for overhead use and later for insulated cables. This led to relatively late installation of modern mills of conventional types and also to the development of continuous casting and rolling techniques particularly suited to aluminium. Although rod rolling is dominated by pure aluminium, a wide range of alloys is also rolled, which calls in some cases for special production techniques for the wirebars. Conventional rolling techniques are basically similar to those usedfor other metals but some characteristics of aluminium demand special techniques. Bar and section rolling is virtually non-existent in Europe, contrary to practice in North America, where the existence of large blooming mills for this purpose has greatly influenced rod-rolling practice.
