Corrosionpedia explains Iron Slag Abrasive

Calcium silicate, another name for iron slag abrasive, is formed from the smelting of iron ore. During the smelting process, the iron is placed into a blast furnace that is also loaded with limestone. The heated limestone forms calcium oxide, which then attaches to the silicon present in the iron ore.

Iron slag abrasive is used in a variety of applications, such as cleaning stone or brick surfaces, or cleaning metals prior to application of paint or other type of coating. It also has many special applications, such as cleaning parts made of wood or other organic materials.
