steel can not be too precise. Third, the difference between hot-rolled plate and cold-rolled plate 1, cold-rolled cold-rolled surface with no oxide, good quality. Hot plate processing surface with hot rolling oxide scale, the plate thickness under the poor. 2, hot-rolled plate toughness and surface roughness is poor, the price is low, while the cold-rolled plate elongation, toughness, but the price is more expensive. 3, rolling is divided into cold-rolled and hot-rolled to recrystallization temperature as a point of distinction. 4, cold-rolled: cold-rolled generally used in the production of strip, the rolling speed higher Hot-rolled: hot-rolled temperature and forging temperature close to 5, non-plated hot-rolled plate surface into a dark brown, The surface is gray. After plating can be distinguished from the smooth surface, cold rolled plate smoothness higher than the hot rolled plate. Through the above introduction, I believe we already know what is the cold-rolled plate, what is the hot-rolled plate it! The difference between cold-rolled plate and hot-rolled plate, over Xiaobian temporarily to share here, I hope for your help, For more cold-rolled plate knowledge, please continue to pay attention to every home decoration
