Project name

LD 3 steel plant

General project description

The LD 3 steel plant is named after the so-called Linz-Donawitz process (LD stands for Linz and Donawitz, two Austrian towns). This basic oxygen steel-making process was developed by voestalpine. Here, carbon-rich molten pig iron is converted into low-carbon steel by blowing oxygen over a lance inside the LD converter. Since the 1950s, this method has been used on an industrial scale.
As part of the modernization of the steel plant, an analog communication system was replaced by a new, modern INTRON-D plus system.
