What is the Aluminum Rolling Process? A 3-Step Overview

If the mill heats the aluminum, this process is called hot working. The specific temperature range for hot working varies by alloy. For example, 3003 aluminum is hot worked at between 260 to 510°C (500 to 950°F), according to AZoM. Hot rolling prevents most or all work hardening and allows the aluminum to remain ductile.

Rolling of Metals: Process and Principles (With Diagram)

The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
