The rolling of thin aluminum foil is a very specific process and differs from conventional cold rolling. This rolling mode is reached at thicknesses below app. 70 μm. With decreasing strip thickness, the specific roll force increases, which leads to an increasing elastic work roll flattening in the contact zone.احصل على السعر

In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its re-crystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature.احصل على السعر
20191125 The conventional cold rolling technology involves coiling with constant strip tension between the last stand and the reel block. In these cases, the value σ 0 is usually set low, not more than ~50 N/mm 2. However, if necessary, σ 0 can be increased even up to 200 N/mm 2 [1, 4–6].احصل على السعر
