  • Integration of Automated Roll-Defect Detection Systems in

    Abstract. The surface of work rolls and back up rolls is worn out during hot rolling of heavy plates and strip steel because of micro structural changes and induced crack propagation. After the operation of the rolls in the mills, the surface will be regenerated by the following grinding process in the roll shops.Difference Between Hot Rolled Steel vs Cold Rolled Steel,Cold rolling is done when the metal is able to form “new grains” as the old ones are deformed by rolling and bending the metal. Typically, mills take hot rolled steel after it’s mostly or completely cooled and work it to its final dimension by either rolling it, extruding it, or drawing the metal over a mandrel.

Three-roll initial-pinch (see Figure 5) or single initial-pinch plate rolls generally are for light-capacity applications and may be electromechanical or hydraulic. They work by pinching the flat sheet between two vertically opposed rolls while the third, offset roll—or bending roll—moves upward to contact and then bend the sheet.
