    In hot rolling, if the temperature of the workpiece is not uniform the flow of the material will occur more in the warmer parts and less in the cooler. If the temperature difference is great enough cracking and tearing can occur. In a flat metal workpiece, the flatness is a descriptive attribute characterizing the extent of the geometric deviation from a reference plane. The deviation from complete flatness is the direct result of the workpi

    Rolling is one of the key processes in metal manufacturing, but there are two ways to ‘roll’ steel: hot rolling and cold rolling. It is a common misconception that these processes relate to a metal’s specification or grade; instead they refer to how a metal is processed at the mill.. Hot rolling

    Cold rolling takes the hot rolled product and processes it further. After hot rolling, the steel is cooled to room temperature, then passed through cold rollers at a temperature lower than its recrystallisation temperature. This rolling process is called annealing and relieves stress and leads to a higher yield strength and greater hardness
