Thermo Mechanical Control Processing in Rolling Mills. Thermo mechanical controlled processing (TMCP) is a technique designed to improve the mechanical properties of materials by controlling the hot-deformation process in a rolling mill. This was originally designed to produce the required external shape of the product.

The process starts when the rolling mill gets aluminum slabs or billets ready for rolling. Depending on the desired materials properties for a particular roll, they must first decide whether to heat the stock or not. If they do not heat the aluminum before rolling, the aluminum will be cold worked. Cold rolling hardens and strengthens the ...

The Hot Rolling Process - California Steel Industries. 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.

Defects stem from a variety of causes such as poor billet quality, worn rolling mill parts, and process malfunctions. Detectable defect types are many and include shells, cracks, pinholes, scabs, inclusions, laps and overlaps (Figure 2), as well as repetitive defects (Figure 3). The detectable defect size is 0.15 mm or larger, depending on product

Rolling equipment is roughly divided into three kinds; namely, hot rolling mills, cold rolling mills, and foil mills. Usually, rolling is performed by applying a load to the materials by forcing them vertically through a pair of work rolls. The work rolls are deformed by the high load during the rolling process.
