2019-12-15furnace operations. The blast furnace must be charged with uniform raw materials if the iron produced is to be consistent in quality. This procedure also insures uniformity in the composition of the slag, and as a result the composition of slag from a given source varies within relatively narrow limits.

What is slag - voestalpine

As the name suggests, the blast furnace slag is generated in the blast furnace, during the production of liquid pig iron, and is mostly processed further into granulated blast furnace slag which is a valuable additive in the cement industry. The main type of metallurgical slag is LD slag, the byproduct of the Linz-Donawitz process.

Metallurgical slag as a component in blended cement

2012-2-18Unlike blast furnace slag, metallurgical slag is rather acidic and it is likely that its higher SiO2 and Al2O3 contents contribute to pozzolanic reactions in strength development. A higher percentage of Na2O and K2O, as well as an MgO content more than 8 may also adversely affect strength development if the metallurgical slag content is increased beyond 50 in slag cements.
