ThyssenKrupp CSA has built a new 5 million t greenfield steel plant in Brazil. This presentation explains the equipment configuration, layout and logistical design of the steel plant, comprising two converters and two continuous casting machines, based on the target product portfolio. The principal challenges during cold and hot commissioning of the plant and the methodology employed during the commissioning to ensure its safe and proper start-upare also explained. To determine the equipment configuration and layout of a greenfield steel plant it is essential not only to determine the target quantity but also theen visioned target product portfolio. A smooth hot commissioning process can be achieved even in agreenfield plant with quite in experienced personnel when operational teams are trained sufficiently, when proper planning procedures are thoroughly executed and when operational and contractor’s team are working closely together. The moment of the production of the first slab impressively demonstrated that 182 km of piles, 85 000 m³ of concrete, 42 000 t of steel structures, 24 000 t of mechanical equipment, 3 000 t of pipes, and 1 600 km of cables are not simply quantities of relatively simple materials, but that these pieces canform something really big, continuously creating value and allowing employees to work safely and proudly in a positive corporate culture and rewarding work environment.
