NLMK Lipetsk has started hot testing at its new furnace for preheating slabs before rolling at Mill 2000. The new reheating furnace will increase NLMK Lipetsk’s hot-rolled steel output by 110,000 tonnes (+2%), reduce energy consumption by 50%, and almost halve air emissions. The new walking beam reheat furnace has replaced the outdated pusher-type furnace. Walking slabs along through the furnace with moving beams eliminates the possibility of surface defects and improves slab reheating parameters. The revamp will boost furnace productivity by 23% to 320 tonnes/hour (2.25 million tonnes per year). The furnace’s advanced control system based on a learning mathematical algorithm is able to adjust the heating process to steel grades without human intervention. Total project capex amounted to RUB 4.3 billion. Ramp-up to full capacity is planned before the end of 2019.
Reheating Furnace No 2 was assembled in 10 months, one month ahead of schedule, with no hot-rolling process interruptions. A full BIM (Building Information Modelling) cycle was used for furnace design, construction and assembly. This technology enabled the company to create a digital twin of the future unit and the construction process, to pre-emptively eliminate potential errors, and to optimize the scope and schedule of construction works at an early design stage.
