“LD slag” owes its name to the Linz-Donawitz process through which it is produced during the production of crude steel. Since it is produced in a converter furnace, it is also known as converter slag. Our product StahLith® L is suitable for a wide range of applications, including stones for water way construction and track ballast. Due to its high lime content, LD slag is also particularly suitable for the production of fertilisers.
