Buderus Edelstahl GmbH has a new dedusting facility in the steel mill at its site in Wetzlar. The new dedusting equipment improves workplace safety, air quality, and steel quality.
Buderus Edelstahl GmbH is a specialist in the production and processing of high-quality special steels. The company has recently invested in a new dedusting facility at its steel mill in Wetzlar, Germany, which extracts 2.4 million m³ of air per hour, five times as much as the previous installation. This investment makes Buderus Edelstahl a pioneer: no other steel mill in Germany dedusts its facilities so forcefully.
Improvements in air and production quality
What makes the new dedusting facility so special is its fully automated response to the operating demands of the steel mill. The deduster extracts the emissions, usually fine dust, at the actual point of production, e.g., at the electric arc furnace, or on the alloying and casting lines. This offers advantages in a wide range of areas:
- Employees: this has greatly reduced employee exposure to dust and improved air quality in the production halls.
- Local population: this investment also benefits the population of Wetzlar, who enjoy significantly better air quality, and thus quality of life, in the immediate surroundings.
- Products: actively filtering dust offers new opportunities for optimizing process technology. This allows the already high-quality special steel to be improved further.
As well as improving air quality, the new facilities are of course also exemplary in terms of energy efficiency.
The facilities were installed within two years and went into operation in August 2014. They were officially opened during a ceremony on Employee Day in October. Planning and construction involved huge challenges as the facilities needed to be customized to meet the particular requirements. The complex facilities also had to be installed in existing buildings and during ongoing operations. The results are impressive: the new dedusting facility filters 2.4 million m³ of air every hour. The filtered air is then expelled into the atmosphere via a 50-meter-high exhaust air tower.
This state-of-the-art dedusting facility marks a milestone in a comprehensive program aimed at making production at Wetzlar sustainable.
