This course looks at refractories, their properties and role in the steel industry and the mechanisms of wear and degradation. It details specific refractories and needs in the steelmaking and casting process ranging from the primary steelmaking vessels to the ladle, tundish and casting refractories. This course looks at the types of refractories used for different applications, their care and maintenance.
