More Durable Lining for Horizontal Copper-Nickel Converters

More Durable Lining for Horizontal Copper-Nickel Converters Results are presented from a study of the durability of the lining of horizontal converters and the reasons for the short service life of the lining’s tuyere zone. The article describes new designs of tuyere-zone linings and new tuyere blocks developed on the basis of the study results. Technologies have been developed for making periclase-chromite tuyere blocks and a heat-conducting bulk refractory which is resistant to slag-matte melts. The blocks are made using a fused material that has a high content of Cr2O3. The durable new lining was tested and introduced on converters at the Alaverdinsk Mining-Metallurgical Combine and Ufalei Nickel Plant. The new linings last 1.5 – 2.0 times longer than the linings used previously. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Refractories and Industrial Ceramics Springer Journals

Abstract

Results are presented from a study of the durability of the lining of horizontal converters and the reasons for the short service life of the lining’s tuyere zone. The article describes new designs of tuyere-zone linings and new tuyere blocks developed on the basis of the study results. Technologies have been developed for making periclase-chromite tuyere blocks and a heat-conducting bulk refractory which is resistant to slag-matte melts. The blocks are made using a fused material that has a high content of Cr2O3. The durable new lining was tested and introduced on converters at the Alaverdinsk Mining-Metallurgical Combine and Ufalei Nickel Plant. The new linings last 1.5 – 2.0 times longer than the linings used previously.
