THE LINING FOR THE INCREASED-RESISTANT HORIZONTAL COOPER-NICKEL CONVERTER

Abstract

The resulting investigation of the lining resistance is given in the article for horizontal converters, and the reasons of the lining's low resistance at the tuyere level zone are discussed. On completion of the investigation the designs of the lining for the horizontal converter's tuyere zone as well as for the tuyere block were developed and described. The manufacturing technologies were developed for periclasechromite tuyere blocks which includes the fused highCr2O3 material, as well as for the thermally-conductive refractory mixtures resistant against the slag-matte melts. The increased-resistant linings were tested and implemented at the JSC «Alaverdinsk Mining and Metallurgical Works» and at JSC «Ufaley Nickel Plant». The employment of the new lining allowed to increase its resistance by a factor of 1,5–2. Ill. 3. Ref. 6.
