Sheets, strips, bars and rods are examples of cold-rolled products. Generally, cold-rolled workpieces are smaller and higher in strength when compared to hot-rolled. Four high or cluster mills would be needed for cold rolling. Cold rolling, however, cannot reduce thickness of workpiece as much as hot rolling in a single pass.
for Continuous Rolling Simple Intermediate Roll Shift maintains the best performance at the various conditions of the strip. UCM-MILL achieves ever stable rolling, that reduces the strip breakage and extends the roll change interval. 4H-MILL IDEAL MILL UCM-MILL ( L > W ) ( L = W ) Flat Edge wave Undesirable contact area
Umumnya, materi kerja yang mengalami cold-rolling jauh lebih kecil dan memiliki kekuatan yang lebih besar dibandingkan dengan materi yang mengalami hot-rolling. Four high atau cluster mill diperlukan untuk proses cold rolling. Namun, cold rolling tidak dapat mengurangi ketebalan materi kerja sebanyak hot rolling dalam single pass.
