"Good course with great information for practical purposes."
Steel Melting 201
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.
Class participants will learn to:
- Explain the difference among steel melting processes.
- List melt-stock components.
- Explain alloying techniques.
- Explain chemistry measurement techniques.
- Explain post-furnace processing variables.
- Describe the quality implications from melting variables.
- Explain proper refractory selection.
- Describe the selection of ladle options (pros and cons).
- Describe the safety procedures and equipment related to the melting process.
