The paper discusses the difference in the formulation concepts of alumina-spinel (spinel containing) and alumina-magnesia (spinel forming) castables and the influence on their physical  properties. The individual property profile will be discussed with regard to the requirements on refractory lining materials for the different zones of a steel ladle.
