Description
The oxygen is often detrimental to the quality of steel produced and deoxidation is an important process. Sulphur is other detrimental impurities in the steel affecting both internal and surface quality, desulphurization of steel is essential during the steelmaking process. And finally the control of carbon is crucial to obtain the steel composition required. In this module, an explanation of different processes to refine the steel composition will be introduced. First, the process of Deoxidation to lower the level of oxygen. Second, the process of Decarburisation to control the carbon level in steel. And finally, the different ways of Desulphurisation will be explained.
What you will learn
- Outline the uses of deoxidation in steel and the common materials used for deoxidation;
- Understand the chemical reactions involved in the decarburisation process and calculate the time needed for it;
- Explain the different ways to achieve desulphurisation.
