摘要：

To extend the life of air tuyeres and reduce heat losses through their surfaces, boron-carbide sealant is applied to tuyeres with a sprayed aluminum coating after heat treatment. The influence of the B4C-based sealant on the heat losses is theoretically assessed. The efficiency of the sealant is confirmed by industrial trials at OAO NLMK and by metallographic investigation of samples from used tuyeres. © 2013 Allerton Press, Inc.
