Abstract

Titanium- bearing wire injection through tuyere is one of the measures to maintain blast furnace hearth which has been eroded. In this case, the migration feature of titanium compound in hot metal inside the hearth was analyzed using numerical simulation method, and the influences of injection position on protection effects were discussed. The calculation results show that the migration path and concentration distribution of titanium compound in hot metal is varied widely with different positions. When titanium- bearing wire is injected through the tuyere which located away from the taphole, titanium compound would distribute both at the sidewall and bottom of hearth. It’s conducive to maintaining the corresponding erosion area. When injected through the tuyere near the taphole, only the sidewall of hearth could be protected. Thus, there exists the optimum injection position for different erosion area, and this position should be determined under comprehensive consideration about the location of erosion area and taphole. The simulation results coincide well with production practice. It shows that numerical simulation can be used for the optimization of feeding position.
