 · A newly developed MgO–CMA–C brick is tested as part of a lining in a 120 t steel‐refining ladle in an integrated steel shop. After 138 cycles a slag coating is formed on the hot face and the corrosion rate is much slower compared with a common MgO–C brick. The formation mechanism of the protective slag layer is investigated.

Corrosion Mechanism of MgO–CMA–C Ladle Brick with High
