Description
The majority of the raw material used in EAF is scrap. It should be selected to obtain the best condition to prepare the basket steel to avoid possible problems in the operation condition.
The power consumption during the EAF process is important to optimise the Tap-to-Tap time. A good basket preparation helps to improve the Tap-to-Tap time. One of the possible problems is related to the electrode breakage during the melt operation due to a bad basket preparation.
In this module, the raw material used in EAF, and the process to prepare a basket are introduced. In addition, power consumption during operation together with an explanation of the thermal load distribution due to burners, and the electrode possible failure are explained.
What you will learn
- Identify the different types of steel scrap used to charge the EAF basket and prepare a basket with different scrap;
- Interpret the typical power schedule in the EAF;
- Distinguish the burners and their role in the melting process;
- Outline ways of avoiding the risk of electrode breakage.
