Radiant tubes operate at a high thermal and mechanical load. A failure of the radiant tubes reduces the heat input to the furnace and therefore the productivity. In the worst case, furnace downtime is necessary. Besides choosing the appropriate material and a good dimensioning of the burner-radiant tube-system, different influences lower the lifetime of radiant tubes. This article gives an overview of the state of the art and experimental and numerical investigations concerning the influences on radiant tube lifetime.

In 2025, the Calderys Group celebrates its 160th anniversary, marking a legacy than began in 1865 in Pennsylvania through the origin of HWI, the brand of the Americas region of the Group.
Nippon Steel Corporation (“Nippon Steel”) and Sanyo Special Steel Co., Ltd. (“Sanyo Special Steel”), a wholly-owned subsidiary of Nippon Steel, were planning to consolidate the production of steel products and free forged products currently produced at Osaka Area of Kansai Works into Sanyo Special Steel in order to generate synergistic effects between the two companies.
20,000 revolutions per minute, 98 percent less CO₂, nearly 100 percent recycling rate – the GMH Group demonstrates how modern steel is revolutionizing electromobility. While electric motors place entirely new demands on strength and precision, Germany’s leading electric arc furnace steel producer responds with innovative materials and closed-loop systems. From rotor shafts to gear wheels: A behind-the-scenes look at an industry in transformation.
