Influence of roll radius on roughness transfer in skin
WebRolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallizationtemperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling. WebThe control of surface roughness is of great significance for measuring the quality characteristics of cold-rolled steel strip. At present, the conventional method is used to monitor the surface roughness of steel strip by random sample inspection, off-line analysis and test, and on-line adjustment of production process, but the method is of some … hope house sedona az
