Mexican steel producer ArcelorMittal México S.A. de C.V has placed an order with Primetals Technologies to supply a hot strip mill and a hot skin pass mill for its production site in Ciudad Lázaro Cárdenas, Michoacán State, on the Mexican Pacific coast.
This will enable ArcelorMittal Lázaro Cárdenas to process the slabs produced in its works on site. The hot strip mill will be erected on a turn-key basis, including power supply, mechanical equipment, drives and automation. Through-Process Optimisation will improve efficiency, stability and product quality across the production route.
The project will be executed in an open consortium with the Mexican construction companies LOMCCI S.A. de C.V and WP Constructora S.A. de C.V. Design capacity is 2.5 million metric tons of hot strip per year. The hot skin pass mill is designed to process 650,000 tons per year. The start-up of the hot strip mill and the hot skin pass mill is planned for 2020.
ArcelorMittal Lázaro Cárdenas is Mexico’s largest steel producer and slab exporter. The company uses DRI as its primary metallic input for steelmaking. This results in higher quality slabs with a uniform grain structure. Liquid steel production capacity is 5.3 million metric tons per year, while slab production capacity currently amounts to 3.8 million metric tons per year. The new hot strip mill and hot skin pass mill from Primetals Technologies will provide ArcelorMittal Lázaro Cárdenas with the potential to process slabs on site.
The hot strip mill (HSM) consists of a roughing mill and a seven stand finishing mill. It will roll slabs with thicknesses of 220 or 250 millimetres. A slab reheating furnace, a crop shear, a strip cooling line including Primetals Technologies Power Cooling system, two downcoilers and the modular coil shuttle car system are also part of the turnkey mill.
All equipment will be engineered and supplied by Primetals Technologies, with supplies also including the water treatment plant, the high and medium voltage electric power supply down to the local subdistribution, the roll shop, a laboratory as well as the required bays and cranes. One indoor and two outdoor coil storages will also be integrated. The hot skin pass mill (HSPM) consists of a powerful mill stand, entry and exit reels, a flattener, a side trimmer and inspection equipment.
