Secondary metallurgy: chemical composition is key


The strict requirements for modern steels make it necessary for molten crude steel to undergo subsequent treatment. This applies to both the blast furnace-to-converter and electric arc furnace methods. In the steel life cycle, the secondary metallurgy stage takes place between the converter or electric arc furnace and the casting system.

Transforming industry is inevitable


Climate change is now affecting our daily life. Most recently, political measures have been initiated to slow advancing temperature increases. One of the results of this political activity is the Paris Agreement, which stipulates climate goals for the first time. The aim is to achieve these goals through green industry transformation, among other measures.

Circular economy: alive and well at Feralpi Stahl


In the German town of Riesa, the home of steel company Feralpi Stahl today, around 24 million tonnes of scrap have been turned into steel for productive use since the business was founded in 1992. The steel produced by Feralpi is made from almost 99% recycled material.

Entering the future with green steel


Green steel is currently the most popular concept in the steel industry’s push to go net zero. The industry’s objective is to make its product, which has been the backbone of industrial production for decades, green in future, gradually reducing its CO₂ emissions to zero in the process.

Is it all product carbon footprint or what?


The steel and metal industry needs to decarbonize. Almost every company has therefore now set its own climate targets in order to reduce its CO₂-emissions. However, there is still no standardized definition for green steel.

Green transformation: clear bonus for steel scrap


In the course of decarbonization, the increased use of steel scrap in steel production is the means of choice for reducing CO₂ emissions, as recycling saves an average of 1.67 t of CO₂ compared with production from iron ore via the blast furnace route.

How the Green Transformation impacts the labor market in the metallurgical industry


Among the three big "D"s, Digitalization, Demographics and Decarbonization, decarbonization remains probably the greatest challenge facing the metallurgical industry.

Hydrogen transport: All in on Ammonia?


Everyone wants green hydrogen, some sooner than others. The areas of application for the eco-gas in the process industry are well known; so are the methods of production - centralized or decentralized, domestic or foreign. But between production and application lies transportation.

With the right technology to green iron and green steel


Technologies for emission-reduced steel production already exist. Plant manufacturers can already incorporate them into a large number of existing and future plants. However, how, what, when and where this can happen depends on several technological factors. We explain what these are here using several practical examples.
