Why nitrogen content must be half that of aluminium in steel

If the free aluminium value does not exceed twice the nitrogen content specified, the value of total aluminium should be used. It is considered that aluminium content above approximately 0.075% will tie up all the available nitrogen, and that an increase in aluminium above this value will give lower than optimum toughness in the base steel.

Slag - Wikipedia

Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.

Kerneos - Calcium aluminates as a metallurgical flux

The use of calcium aluminate flux improves traditional slag practices and even opens the way to superior performance: Rapid slag formation . Thanks to its low melting point (< 1,325° - 1,375° C), calcium aluminate flux melts on contact with the steel, and can dissolve other reagents such as lime if the additions are proportioned correctly.

Creating Steel | HowStuffWorks

Another way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter.The heat of oxidation raises the temperature and keeps the iron molten. As the air passes through the molten pig iron, impurities unite with the oxygen to form oxides.
