quick roll change hot trip mill Fundamentals of Roll Cooling and Control of Flatness at roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and inter-stand strip temperature rarely exceeding 160 oC depending on product.

The Hot Rolling Process. 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.

The aims of the project are to replace the existing cycloconverter drive system while also increasing performance for future products. ... It has had a reputation for expertise in the processing of hot-rolled Hohenlimburger medium-wide strip for more than 150 years. ... The medium-wide hot strip mill is continually modernized.

quick roll change hot trip mill mtnbybo.co.za. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Backup rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).
