軋輥是軋制生产中最重要的工具之一,它的使用情况在很大程度上决定了生产效率和生产成本。軋輥(特别是热軋輥)的工作条件是很严重的。它所受到的負荷是多种的,在压延时軋輥表面受很大的应力,例如初軋輥在压延时受力达500～800吨,这样表層金屬就反复地受着拉应力和压应力而容易疲劳。再則热軋鋼时,鋼坯的溫度很高,因此在軋輥与鋼坯接触的点上溫度也升到相当高的程度,根据資料可以达到700℃以上,而
Roll is one of the most important tools in rolling production, and its use largely determines the production efficiency and production costs. Roll (especially hot roll) working conditions are very serious. It is subjected to a variety of loads. The rolling surface is subject to high stresses during rolling. For example, the initial roll is subjected to a pressure of 500-800 tons during rolling so that the surface metal is repeatedly subjected to tensile stress and compressive stress. fatigue. Further hot-rolled steel, the billet temperature is very high, so the contact point of the roll and billet temperature also rose to a very high degree, according to the information can reach more than 700 ℃, and
