The hot strip mill 2 at thyssenkrupp Steel in Duisburg, Germany has produced 250 million tons of hot-rolled steel since it went into operation in 1964. Measuring around 700 meters, the mill ranks among Germany’s largest industrial facilities and rolls up to 5 million tons of high-quality steel annually — mainly for automotive applications.
Hot Strip Mill 2 has an annual capacity of around 5 million tons and processes widths of up to 2,030 mm and thicknesses of 1.5 up to 25.4 mm.
With the new walking beam furnace, launched in November 2022, slabs are transported particularly gently during energy-efficient heating — ensuring flawless surfaces, ideal for demanding outer skin grades and high-strength multiphase steels. In the future, the furnace can also be operated with hydrogen to reduce CO2 emissions.
The water management system for the cooling process in the hot strip mill was comprehensively modernized in spring 2025: thanks to a circulation rate of 97 percent for around 200 million cubic meters of water per year, the plant operates in a resource-efficient manner and ensures maximum process stability. And last but not least, by recovering furnace waste heat to supply hundreds of homes in the Lower Rhine region, Hot Strip Mill 2 combines maximum efficiency and quality with a sustainably designed production process.
