Oxygen is also used (oxy-fuel process) for heating of the steel. During steel making process, the main sources of oxygen in steel are as follows. Solubility of oxygen in liquid steel is 0.23 % at the steel making temperatures ( 1600 – 1700 deg C).

Does steel contain oxygen?

This means that, for instance, a steel with 0.1 percent carbon, at equilibrium, contains about 0.025 percent, or 250 parts per million, dissolved oxygen. … These float to the surface of the steel, where they are absorbed by the slag.

What is oxygen used for in steel?

Oxygen is used in steel reheating furnaces. In particular, oxygen is used for enrichment or two run oxy-burners, as blast furnaces and rotary furnaces, respectively. Using oxy-fuel burners in this process contributes to reduced fuel consumption when compared to other gases.
