There is almost no end to the uses of high-grade steel strip in today's world. They include everything from aircraft to beverage cans. That explains why we design our cold rolling mills to be just as versatile. What's important to you are not only high flexibility and product quality, but also sustained, cost-effective operation of your plants.

Introduction to Rolling Process - Assets

1.2 Hot and Cold Rolling Processes From metallurgical point of view, rolling process can be classified under two broad categories, namely (i) hot rolling and (ii) cold rolling. 1.2.1 Hot rolling In hot rolling the material is rolled at a temperature higher than its recrystallization temperature. The advantage of hot rolling is twofold.

Cold Rolling - an overview ScienceDirect Topics

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].
