Laser beam welding in a vacuum (LaVa-welding) is a new and highly innovative process. Compared to conventional laser beam welding, it is characterized by an increase in process stability [1] with a simultaneous increase in quality (comparable to electron beam welds [2]) and weld penetration depth [3]. Conversely, this also means that a required penetration depth can be achieved with significantly reduced energy input by up to 60 % [4], Figure 1.

The EU Commission has granted thyssenkrupp Rasselstein GmbH an extension of the permissible period for using chromium trioxide. With the publication in the EU Official Journal on 21/10/2020, new review times for the use of chromium (VI) now apply for the production of tinplate and special chromium-coated packaging steel from the company. The period expires on 21/10/2027 for tinplate and on December 31, 2028 for special chromium-coated steel.

No material is as substainable as steel. All the more reason why green steel is one of the main topics for the steel industry in the new decade. However, competences and technical possibilities have reached different levels of development across the sector. One of the pioneers in the manufacture of green steel is Deutsche Edelstahlwerke (DEW). The company in the SCHMOLZ + BICKENBACH Group offers its customers solutions that are low on CO2.

Centrifugal fans in steel industry are often exposed to rough and challenging conditions like vibrations, high temperatures and abrasive particles. While vibrations can mostly be avoided by balancing measures and temperature resistance achieved by the right choice of material and dimensioning of cooling discs, a resistance against abrasive particles still is a challenge for many centrifugal fans.

For the most efficient use of raw materials in the production process, the processing of reject materials and by-products of the foundry and machining industries is increasingly gaining in importance.
