  • Roll Cooling Lechler

    In the metalworking rolling process in hot and cold rolling mills heat is generated by friction and deformation in the mechanical forming of the rolling stock. As a result efficient cooling of the rolls as well as the surrounding roll area is essential for the forming process in order to ensure stable roll temperatures and effective heat

  • Steel Forming Process Hot Rolled Cold Rolled Forging

    Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. The cold rolled process creates a finished product that is more precise dimensionally than a hot rolled

  • Roller Mill Maintenance00CPM

    Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.
