Behaviour of magnesia–carbon refractories in vacuum–oxygen
Direct carbon burnout and the MgO reaction are the main causes for their failure in the freeboard. However pitch bonded magnesia refractories are able to compete with magnesia–chromite bricks in the ladle bottom and in the lower metal bath region where
