Abstract:
Titanium-bearing wire injection through tuyere has been proved to be available for maintaining eroded hearth of blast furnace. In the current work, a three-dimensional hearth model based on computational fluid dynamics is proposed to simulate the migration path and concentration distribution of titanium compound in hot metal. The model considers the effects of porous medium under the conditions of the laminar flow as well as floating and inactive deadman. Based on the modeling results, the migration path and concentration distribution of titanium compound in hot metal is varied widely with different injection positions. The different floating heights the deadman are analyzed and the results shown that titanium compound distribution is similar when the floating heights are 0 m, 0.3 m and 0.6 m respectively. The model is expected to be helpful to provide some suggestions for hearth protection and prolong the campaign of the blast furnace.
