contactThe standards applied in different countries to set the requirements for cold-rolled steel, such as EN 10130, EN 10268, EN 10209, ASTM A1008 / A1008M, DSTU 2834, GOST 16523, GOST 9045, GOST 17066 and others, specify steel grades and size ranges for cold-rolled coils, their application (profiling, cold forming, enamelling, general use, etc),
contactIn 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.
contact2016425 · •The friction varies from point to point along the contact arc of the roll. However it is very difficult to measure this variation in µµµµ, all theory of rolling are forced to assume a constant coefficient of friction . •For cold-rolling with lubricants, µµµµ~ 0.05 –0.10. •For hot-rolling , µµµµ~ 0.2 up to sticky condition.
