Description
The processes in which iron is molten take place inside the Blast Furnace (BF). A blast furnace works by blasting hot air up through the furnace while fuels, limestone, and ore move continuously through the top of the furnace. The method used in blast furnaces have been used since the 1500's. There are several chemical reactions taking place inside the Blast Furnace. In this module A description of the Blast furnace process is given in detail, including the chemical reactions. Then, the zones of BF are described to understand the physical process. The pulverised coil injection to improve the cost of steel is explained as well as the different parts of BF. Finally, dephosphorisation and desulphurisation are detailed.
What you will learn
- List the different zones and their physical and chemical states;
- Explain the thermodynamics and reaction kinetics of the iron ore reduction;
- Understand the functions of tuyère and raceway, and the importance of coke combustion;
- Write down the main chemical reactions in different zones.
