Slag processing for the metallurgical industry

With our know-how, we ensure that almost all by-products of the steel and metallurgical industry can be profitably reused.

Slag processing for the metallurgical industry

Slag is inevitably produced as a by-product in steelmaking. Ferro Duo products make it possible to filter the slag from the blast furnace process by periodically tapping it off. Our products ensure that the slag can then be converted into high-quality granulated blast furnace slag, which in turn can be  used by the cement industry. With our know-how, we ensure that almost all by-products of the steel and metallurgical industry can be profitably reused.

Variable use: slag

Slag is a necessary by-product of metallurgical processes and can be used in a wide range of industries. Ferro Duo has specialized for years in processing by-products, for example from the steel and metallurgical industry, with added value. Slags can be used in a variety of ways: in road construction, ground as an additive for various types of cement, as a blasting agent or in the production of fertilizers. The slags easily meet the expectations placed in them. 

Granulated blast furnace slag

Granulated blast furnace slag is a highly valuable product. The conversion process into granulate form is only possible with the most modern techniques and requires years of experience. Finely ground, it serves as the basis for a wide variety of cements.

LD - slag

Converter slag has been used for over a hundred years as converter lime for lime fertilization in agriculture and forestry after a natural decomposition process and mechanical processing.

Copper slag

This siliceous slag is produced in thermal copper metallurgy and is successfully used as an iron carrier in cement clinker production, as a blasting agent and for surface refinement in the manufacture of concrete products.
