on wear is another issue Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest
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.

Aluminium slabs are heated to a temperature of around 525°C and then passed repeatedly through a hot rolling mill until either the required plate thickness is obtained or until the metal is thin enough (generally about 3 mm thick), to be coiled ready for cold rolling - the last 3 or 4 hot rolling passes are usually performed sequentially.
Mill rolls Rolls for rolling mills
As a joint owner of the South Korean machine building plant BUKANG (Incheon city) that was founded in 1986 and currently is a leading manufacturer in the South Korea specializing in production of interchanging equipment and spare parts for various metallurgical units, manufacturing and engineering company ENCE offers rolls of rolling mills (mill rolls).
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 magnitud 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 STEEL ROLLING
Hot rolling of steel is relatively new technique, probably due to the fact that steel was not available in large quantities until the end of seventeenth century By the end of seventeenth century, hot mills using grooveless (“flat”) rolls were being employed to reduce the thickness of cuboids into sheets.
