  • Talk Rolling (metalworking)Wikipedia

    The seventeenth century saw the hot rolling of bars of ferrous materials into sheets throughout Europe .. These mills were single stand mills. .. the first recorded use of successive stands arranged in a tandem mill was for the hot rolling of wire rods in England in 1766 and in 1798 a patent was issued for a tandem mill for rolling iron 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.
