Before high-quality iron can be made from iron ore, SCHAEFER PRECAL® is already employed on the sinter belts to pelletize the ore. After the ore pellets have been melted in a blast furnace, SCHAEFER PRECAL® once again becomes active: It binds unwanted by-product components in a light slag, which can then be easily separated from the iron.
- Stainless steel
SCHAEFER PRECAL® is used in the steel mill to bind and remove secondary constituents persisting in the iron, such as sulfur, phosphorus, carbon, silicon and manganese. This makes it possible to produce high-purity steels for premium-quality applications.
If the secondary constituents in the steel are reduced even further and the steel attains a specified purity, it is also referred to as stainless steel (or the different alloys). It is here that SCHAEFER PRECAL®'s outstanding chemical purity makes it the ideal choice.

Lime is essential to produce high-quality types of iron and steel. The addition of SCHAEFER PRECAL® as a slag former reliably ensures the binding and removal of unwanted impurities.
