HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS
The demand for hot rolled strip is growing in multiple ways.
To remain competitive, new and existing mills must be as well prepared for this challenge as possible. The production of hot strip is a key element of steel production. Given that close to half of all steel produced is hot-rolled to strip, mills require maximum throughput and availability combined with geometrical precision and the ability to create optimum material properties.

Hot strip mill
Our solution
An advanced Pair Cross mill with mill stabilizing device is used for stable operation of the process for producing thinner and harder steel. Meanwhile, a powerful crop shear and downcoiler are supplied to meet the increasingly complex requirements involved in the production of heavy gauge steel. For higher overall productivity, the slab sizing press is introduced for aggregation of slab width. Furthermore, to ensure smooth project execution, Primetals Technologies also provides first-class support for installation, erection, commisioning, and staff training.
