Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35].

Steelmaking provides the most common application of rolling operations. Figure (5-2) illustrates the sequence of steps in a steel rolling mill to show the variety of products made. Similar steps occur in other basic metal industries. The work starts out as a cast steel ingot that has just solidified. While it is still
2.4 Straightening, Bending and Rolling Rolled steel may get distorted after rolling due to cooling process. Further during transportation and handling operations, materials may bend or may even undergo distortion. This may also occur during punching operation. Therefore before attempting further fabrication the material should be straightened.
Establishment. The Saucona Iron Company was established by Augustus Wolle.

Starting materials such as blooms or slabs at an elevated temperature flow from the continuous casting process directly into the rolling mills. In smaller operations the materials start at room temperature and must be heated either in a soaking pit, or by induction heating before being fed into the mill.
