contactThree rolling processes. We differentiate three rolling methods: conventional hot rolling at high forming temperatures, normalizing rolling and thermomechanical rolling. The pre-material is the same for each of the rolling methods: a homogeneously heated slab from the heating furnace with a relatively coarse-grained microstructure.
contact20151119 · 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.
