Greasing Process In Cold Roll Mill

The bearing chocks of the working cylinders are subject to permanent wash out by cold rolling lubricants and are subject to heavy loads.The use of lubricants with excellent anti-wear properties and resistance to wash-out is essential. As with hot rolling, the spacing of greasing time is necessary to limit maintenance operations between each change of cylinder

    Jan 21, 2019 Cold rolling is a process that occurs after hot rolling in order to reduce the thickness, increase the yield and tensile strength and pliability of metal. It is a relatively expensive and labour-intensive process, but the improved mechanical properties increase the value of the finished product, whether that is a sheet, strip, or coil

    Sep 11, 2014 Cold Rolled Steel. 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. This process will produce steel with closer dimensional tolerances and a wider range of
