Innehåll

The course is designed to familiarize students with theoretical/practical contexts for the manufacture of iron and steel castings, the important characteristics of iron-based alloy casting. The students will get familiar with different methods of melting and casting steel and cast iron. The course is also focusing on the quality control methods.

The course includes the following elements:
- Fundamentals of Ferrous Metallurgy.
- Melting technology of Cast Iron. (Melting furnaces, melting methods, charge optimization,)
- Liquid treatment and Ladle metallurgy. (Alloying, desulfurization, inoculation, modification.)
- Quality control of the liquid iron. (Chemical analyses, dissolved gas analyses, test of fluidity, cooling curve and volume change analyses).
- Quality control by characterization of cast iron. (Wedge tests, characterization of cast iron by morphology)
- Elaboration of steel for shape casting. (Melting, charge, de-oxidation and other treatments, control methods)
