  • The Hot Rolling Process - California Steel

    The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

    2017-9-13u2002·u2002Energy Efficiency Drives for Rolling Mills: High efficiency motors can save approximately 1-2% of the electricity consumption. Assuming an electricity demand of 220 kWh/t-hot rolled steel, the electricity savings are estimated to be 4 kWh/t-product (Worrell et al., 2010. p.100). Emission reductions are estimated at 1.6 kg CO 2 /t-product.

  • Hot Rolling - an overview

    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.
