  This process of cleaning the hot rolled product is known as pickling. These cleaned (pickled) products are then passed through rollers at room temperature. The rolling mills are similar to that used in hot rolling. The cold rolling process has the advantage of providing close dimensional tolerance up to mm. It also improves toughness ...

  Metal Rolling

  Rolling is most often, (particularly in the case of the conversion of an ingot or continuous casting), performed hot. At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing operations such as forging, sheet metal working, wire ...

  Hot Rolling

  When hot rolling steel in the laboratory, using relatively small rolling mills, values of 4–20 kW/m 2 K appear to be the correct magnitudes. If modelling hot rolling of steel under industrial conditions, values of 50–120 kW/m 2 K are more useful. In both cases, the layer of scale is an important parameter.

  Hot rolling and rolling defects: Front and back tensions: We have seen that the rolling load is dependent on roll diameter, higher the roll dia, higher the roll force. Similarly, smaller reductions requires lower roll force. In order to reduce the roll force, we can reduce roll diameter, or reducing the friction. Another method of reducing rolling force is to apply a small tensile force on ...
