651-4219-00L  The Mineralogy of Steelmaking

SemesterSpring Semester 2016
Lecturers
Periodicitytwo-yearly recurring course
CourseDoes not take place this semester.
Language of instructionEnglish


AbstractIron is utilised by mankind since thousands of years and the present day world wide production of about 1.5 billon tons of steel makes the latter to one of the most important and irreplaceable industrial products. This course will communicate the relevant solid-liquid-vapor reactions along the production route of an integrated steel plant as an example for applied mineralogy.
ObjectiveThis course will put emphasis on applied mineralogy and show how concepts, familiar to Earth scientists, are being applied to industrial processes.
ContentThe course will cover the following topics:
- Pre-blast furnace processing of ores, coals and additives
- Melting and reduction in the blast furnace
- The "Basic Oxygen Furnace": de-carburisation, and the conversion from "hot metal" towards steel
- Secondary steelmaking: de-oxidation and non-metallic inclusions
- By-products: Chemistry, properties and applications of blast furnace and secondary steelmaking slags
- Chemistry and properties of refractory materials
- The role of silicate liquids during casting steel
Prerequisites / Notice4 day block-course with lectures between 10-12h and 13-15h, with a total of 16 hours.
