Voestalpine operates new pickling line from Andritz
Andritz has completed the supply of a continuous pickling line, acid regeneration plant, acid purification plant, and silicon removal systems to voestalpine’s site in Linz, Austria.
These plants have been integrated into voestalpine’s cold rolling mill #3 in Linz, Kallanish learns from Andritz. The plant supplier’s equipment enables voestalpine to perform pickling and cold rolling in a combined plant. Andritz supplied what it says is the world’s most modern acid regeneration plant, complying with the highest environmental standards and enabling flexible production of high-purity iron oxide.
The continuous pickling line is designed to process advanced steel grades and special materials for e-mobility. It has a capacity of about 1.8 million tonnes/year and operates with hydrochloric acid, which is recycled in the acid regeneration plant. Andritz underlines a recovery rate of almost 100%, thus making a substantial contribution to environmental protection.
“The new installation enables us to increase the production quality of high strength and ultra-high strength steel strip,” says Walter Schickmaier, business unit manager at voestalpine. The products will target the automotive, household appliance and construction industries, as well as electrical steel for e-mobility.

Andritz to modernize voestalpine’s hot-dip galvanizing line in Linz
Andritz has received an order from voestalpine to modernise the electrical and automation systems of a hot-dip galvanizing line at the steel mill in Linz, Austria.
The processing line has been continuously modernised since it began operations in 1973. Over the years, numerous rebuilds and upgrades have resulted in the use of a variety of electrical and automation systems, Kallanish understands.
The technology supplier says it will replace this variety with a unified, consistent, and user-friendly electrical and automation system that supports efficient operation. To minimise the impact on production, it will implement the modernisation in several stages, with completion scheduled for the end of 2028.
The order underscores the long-standing cooperation between the two Austrian groups, Andritz notes.

SKF decarbonises production using Austrian and Swiss Steel
European roller bearings producer SKF and voestalpine Wire Technology have produced the first prototype bearing made from steel that contains hydrogen-based direct reduced iron (H-DRI).
SKF and voestalpine have been working together since 2022 to explore the possibilities of using H-DRI steel for bearing applications, Kallanish hears from the Sweden-based company. The spherical roller bearing prototype was handed over to voestalpine Wire Technology at SKF’s factory in Steyr, Austria. Spherical roller bearings can be used in many different applications and industries, such as marine, pulp and paper production, mining and construction.
“Steel is a critical raw material in bearings, and to achieve the change and speed needed in decarbonising bearing production, the whole industry must come together,” says SKF chief technology officer Annika Ölme.
SKF recently announced it also started sourcing low-carbon steel from Swiss Steel. Since the beginning of the year, Swiss Steel has been delivering its GreenSteel Climate+ brand made at German unit Deutsche Edelstahlwerke (DEW) exclusively to SKF.
