| Abstract: | Four Kinds of tuyere damage mechanism, namilg, burning, cracking and crazing,wearing and bending were described according to the working atmosphere of tuyere. The factors affecting tuyere life were analyzed from structure, workmanship, tuyere-cooling, the BF operation,pulverized coal injection and so on, and a series measures to prolong tuyere life were put forward. |
