ControlIT for Cold Rolling Mills Technological control for cold rolling processes Rolling of flat metal products is a complex proc-ess where the quality of the product is influenced by various factors like incoming material, me-chanical and electrical equipment, lubrication, control strategies etc. The significant quality parameters are: material
Cold-rolled sheet steel is produced from hot-rolled sheet with additional processing steps such as pickling, cold reduction, annealing and temper rolling. Cold-rolled steel is a product that has been cold reduced, as opposed to hot-rolled, in order to impart specific mechanical properties, surface finish, gauge tolerance and strip shape.

Hot and Cold Rolling Processes in Steel Manufacturing; Non-contact thickness gauges for hot- and cold-rolling mills provide precise, real-time measurements during high-speed production of steel plate and sheet to help you meet the tightest tolerances, ensure your products meets the most precise specifications, and maximize raw material use.
Flying shears. Steel mills use Flying Shears for cutting profile metals and bars during the rolling mill process.These can be fully automated with a motor and a heat sensor depending on the application. Custom designed Flying Shears can be semi-automatic or fully automatic depending on customer needs. Steel mills choose to have Flying Shears custom designed based on their own specific needs.
roll surfaces as well as accumulating fibers and other papermaking raw materials were limiting paper machines' speed and runnability. Thus, the doctor blade was invented to remove excess water and impurities, keeping roll surfaces clean during paper machine operation. Around the same time, the first rigid doctor blade holder was invented.
