Introduction to ferroalloy resistant materials

Ferroalloy (English Ferroalloy), the broad sense of the ferroalloy is to steelmaking as a deoxidizer, element additives, etc., into the molten iron to make the steel has a certain characteristic or to achieve a certain requirement of a product. A master alloy of iron with one or more elements, used chiefly in the smelting of iron and steel. In the iron and steel industry generally also all steelmaking with the master alloy, whether containing iron or not (such as silicon calcium alloy), are called "ferroalloys".It is also customary to include certain pure metal additives and oxide additives.

It is also customary to include certain pure metal additives and oxide additives. Ferroalloys are generally used as deoxidizers: to remove oxygen in molten steel during steel-making, and some ferroalloys can also remove other impurities in steel such as sulfur, nitrogen, etc. Alloy additive: according to the requirements of the composition of the steel, alloy elements are added to the steel to improve the performance of the steel.Instant: added to molten iron before casting to improve the crystalline structure of cast iron.

The main element of ferroalloy is a generally higher melting point, or its oxide is difficult to reduce, difficult to smelt pure metal if together with iron is easier to reduce smelting. The use of ferroalloys in iron and steel smelting, in which iron is not only harmless but more advantageous because it is easy to melt in molten steel. Therefore, most of the deoxidization and alloy addition in the steelmaking process is in the form of ferroalloy. Ferroalloys are generally brittle and cannot be used as metals.
