In chemical composition the experimental chrome-spinel-periclase refractories are characterized by a high degree of purity. The total content of impurity oxides of silicon, calcium, and iron does not exceed 2%. The parts possess increased density, porosity, and slag resistance but a lower heat resistance than the imported refractories with a silica content of 0.5%. Comparative tests of the experimental chrome-spinel-periclase parts (area of about 0.5 m) and the imported refractories with a silica content of 0.5% in the slag belt of an ASEA-SKF installation ladle showed similar lives of them. For a final experimental test it would be desirable to produce a larger experimental production lot of the chrome-spinel-periclase refractories and to test them in the slag zone of ASEA-SKF ladles.
