Baosteel has completed a major gearbox overhaul on its 2050 mm hot strip mill in Shanghai, supplied by SMS group. The upgrade, carried out during the plant’s 2025 annual shutdown, included online adjustments, disassembly, inspection, bearing replacements, and reassembly—without additional downtime.
SMS group provided full support from technical planning to on-site commissioning, ensuring precise execution and detailed inspections that will guide Baosteel’s long-term maintenance strategy.
With a design capacity of 4 million tons per year, Baosteel’s hot rolling line—commissioned in 1989 and enhanced with a slab sizing press in 2013—regularly produces over 5 million tons annually, underlining its strategic role in China’s steel industry.
The project highlights SMS group’s technical expertise and commitment to long-term partnerships with Baosteel.
