Reactivity and corrosion of refractories used in metallurgy: steel-making, non-ferrous, foundry.
Impact on cleanliness and metal quality.
Refractory products are not only strategic for the production of metals and alloys, but they also have a direct influence on the quality of elaborate grades.
This Fire course reviews the impact of reactivity and corrosion on :
- the refractory wear
- the inclusionary cleanliness and quality of metallurgical products.
It mentions all the important developments that will limit the contribution of refractory products concerning wear, oxide cleanliness, steel desulphurisation, Ca treatments of alumina de-oxidation inclusions, carbon pick up for ultra-low carbon steel, clogging phenomena and atmospheric oxidation, in conjunction with efforts of the metallurgists to produce clean alloys.
The course is focused on
- Students with study majors in refractory and ceramic engineering, metallurgy and materials (Master or PhD level)
- Interested engineers with an employment in the refractory manufacturing or refractory consuming industry
- One focus is the iron and steel industry, but also other high temperature metallurgical processes are discussed.
The F.I.R.E Compendium series 2 “Corrosion of Refractories: The Fundamentals, Testing and Characterization Methods and the Impact of Corrosion will be provided to participants.
