Abstract

High quality products at ever-lower production costs are the main objectives of producers of hot-rolled sections. Today various rolling mill concepts are available for the production of sections and they are all aimed at the production of superior products with closer tolerances and lower conversion costs. The PSP-Profile Sizing Process is the latest Danieli cost-breaking innovation for the production of superior quality medium and heavy sections and rails. The PSP is the optimal combination of two rolling technologies merged in an innovative process, featuring highly productive reversing rolling in a 3- stand intermediate/pre-finishing mill, plus a single continuous “Sizing” pass at a separate independent finishing stand. Installed after a reversing Break Down mill, the PSP rolling line includes a 3-stand UFR ultra-flexible reversing mill and an independent continuous finishing “Sizing” stand, followed by a HiPROFILE® laser gauge for constant contactless rolled stock measurement and automatic control/self-adjustment of mill rolling parameters through the SCS-Section Control System. This article describes in detail the PSP technology and its application for the competitive production of superior quality beams, sections, special profiles and rails.
