内容简介

Direct-bonded and semi-rebonded magnesia-chrome bricks are used in the tuyeres of copper converters. At present, the cause of wear is mainly structural spalling due to penetration of copper slag and raw copper. The improvement of erosion resistance was investigated, because it is known that the change in operating conditions will accelerate it.
