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.

Failure analysis of work rolls of a thin hot strip mill

2015-4-1  In hot rolling mills, premature failure of rolls is a major concern as it adversely affects the mill operation as well as production. Analysis of failed roll materials and actual rolling conditions in service are therefore necessary to understand the roll failure mechanism and thereby improve the wear resistance and extend the service life of rolls.

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.

Wear of hot rolling mill rolls: an overview ScienceDirect

An overview of roll materials is given including adamites, high Cr materials, high speed tool steels and compound rolls. Non-uniform wear, recognised as the most detrimental phenomenon in section rolling, can be controlled by roll pass design. This can be achieved by computer-aided graphical and statistical analyses of various pass series.
