Montanstahl's hot rolling mill forms profiles from rods having twenty to sixty millimeter diameter rather than the typical billetbased steel. The internally developed system operates using up to six small stands which has reduced tooling costs as a consequence. So we can produce maller batches: a minimum run for a carbon steel section is 15 ...

When hot rolling steel in the laboratory, using relatively small rolling mills, values of 420 kW/m 2 K appear to be the correct magnitudes. If modelling hot rolling of steel under industrial conditions, values of 50120 kW/m 2 K are more useful. In both cases, the layer of scale is an important parameter.
