摘要

Process technology of spinel periclase carbon refractory productionon the base of fused periclase and alumomagnesium spinel powders isdeveloped at the JSC Magnezit Works. Pilottesting of the refractories in the ladle showed that they arecompetitive with the best foreignanalogs. The use of the refractories thusdeveloped in the working layerof the bottom lining and nipple of thevaccum chamber is found efficient.Study in the field of developing therefractories with enhanced servicecharacteristics for the slag-line area ofthe ladle is in progress. Theaforementioned refractories are expectedto be also used in some other metallurgical installations.
