Steel Melting 201

 

"Good course with great information for practical purposes."

Overview

This course will study the operations of steel melting furnaces including electric arc and induction, the process steps during charging and startup, melt down, chemistry slag control, alloying, tapping, and process documentation, post melt processing methods, Argon Oxygen Decarburization (AOD) and Vacuum Oxygen Decarburization (VOD), melt quality control of undesirable elements with sampling and chemistry measurements, ladle selection and considerations, including maintenance and safety procedures.

Learning outcomes

Class participants will learn to:

  • Explain the difference among steel melting processes.
