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.

Evolution of artificial defects during shape rolling

2012-4-24  In hot rolling of wire rods, the deformation behaviour of the rolled billets is very complex and because of this, roll pass design is, at present, essentially a trial-and-error procedure. The pass design sequences usually used in mills are “square-oval” and “false round (round)-oval”, but it is also common to use “diamond-square” and “diamond-diamond” sequences. As the market demands for high quality wire rod

Behaviour of surface defects in wire rod rolling.

Any wire with defects must be rejected as scrap which is very costly for the production mill. Thus, it is very important to study the formation and evolution of defects during wire rod rolling in order to better understand and minimize the problem, at the same time improving quality of the wire rods and reducing production costs.

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.
