Description
The modernization of the Plate Mill at People Steel Mills (PSM) focused on the implementation of an advanced descaling system to enhance operational efficiency, product quality, and energy performance. Supplied by INTECO Rolling Mill Technologies, this targeted upgrade improves the production of alloy and special steels while contributing to more sustainable plant operation.
A key element of the project is the installation of a two-stage descaling system, consisting of a primary descaler at the furnace exit and a secondary descaler at the roughing stand entry. This configuration effectively removes both primary and secondary scale, leading to improved surface quality and reduced defect rates. In particular, the surface quality of high-alloy plates is significantly improved through proper descaling of the slabs. The system is designed to handle a wide range of input materials, including blooms, slab ingots, and continuous cast slabs. It incorporates real-time laser-based thickness measurement for automatic height adjustment, optimized nozzle positioning, and adaptable descaling forces tailored to different steel grades.
The paper provides an overview of the entire project, from the early conceptual stage through to successful implementation. It outlines the key technical features of the installed system and presents operational results, as well as practical experiences gained during commissioning and production.
