The aluminum rolling process takes place over three steps. 1. Preparing the Aluminum Stock. Before making rolled aluminum, a rolling mill must decide if it will hot or cold work the stock. This decision largely depends on the material properties desired for a specific roll. If the mill decides to cold work the aluminum, the material will not ...

The heart of the temper mill is the cold rolling mill stand which produces the temper pass. It will include electric powered drive motors and speed reduction gearing suited to the process desired. The design of the rolling mill can be a 2high or 4high (even 6high in some cases). The mill stand can be work roll driven or back up roll driven.

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 finetuned 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.
