Cold Rolled Mill Process

Cold rolling is used to reduce the temperature of the material being worked with while also increase how hard and strong the material gets during the rolling mill process. During this process, the overall finish and granule structure of the material is is made more pure and workable

    Cold pilgering is a rolling process for metal tubes that reduces diameters and wall thicknesses. The Process. Located inside the tube is a stationary mandrel (1) which tapers in the rolling direction. This is attached to a long mandrel bar (2) which is secured in, and rotated by, a thrust block. Two dies (3) form the tubular stock in the same way that a rolling pin rolls out pastry

    Oct 08, 2014 In cold rolling process, usually no heat is applied to the hot rolled strip before rolling. However, frictional energy at the contact surfaces of the strip being rolled gets converted into heat. This heat may increase temperature of the strip being rolled in rapid adiabatic process to a level of 50 deg C to around 250 deg C

    The cold rolling process runs at room temperature and usually under oil lubrication. In a few cases an oil/water emulsion is used, which enhances cooling but requires careful water removal before coiling. With the lubrication also used for local cooling, cold rolling allows a good control of shape, flatness and surface of the finish gauge sheet

    Jan 21, 2019 In simple terms, cold rolling is an industrial process used to change the material properties of sheets or strips of metal. The metal is fed between two rollers which compresses it. The resulting mechanical properties vary, depending on how much strain is applied. The main benefits of cold rolling are that it results in a smoother surface, greater dimensional accuracy and increased hardness
