    Hot Rolling - an overview | ScienceDirect Topics

    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.
