Computer Controlled Continuous Tandem Cold Rolling …

1983-1-1 · The capacity of a cold-rolling tandem mill can be substantially increased using fully continuous operation. As a result, the idle times caused by threading the individual coils in and out and the off-size lengths disappear. Extended mechanical mill components, e.g. welding machine, coil looper, have been combined to form a novel overall concept.

Cold Rolling

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].
