摘要

The phenomena of tuyere upward-warp have been found at No.6 blast furnace in Kunming Steel Company China after its blow-in,which has made a great impact on the practical production of the furnace.Thus,a number of efforts have been made to elucidate the mechanism of this phenomenon.The results of investigation and tests revealed that the enrichment and expansion of zinc in the tuyere bricks is the main factor leading to the tuyere upward-warp.The eroding behavior of zinc is that the inner structure of the tu...
