| 摘 要： | 建立高炉铜冷却壁三维传热模型,利用有限元软件ANSYS进行稳态传热分析,研究了钒钛磁铁矿冶炼时挂渣特点。分析结果表明,由于含钒钛高炉渣铁珠含量高,使渣皮显著增厚导致渣皮稳定性下降。将铜冷却壁热电偶测量点温度控制在60～80℃,可以提高渣皮稳定性,保证铜冷却壁安全工作。在现有工艺条件下,把水速从2.3 m/s降低到1.5 m/s对挂渣影响很小。 |

| Abstract: | A three dimensional heat transfer model of copper cooling stave is built and analysis on steady-state heat transfer is carried out by finite element software ANSYS to investigate characteristics of slag skull generated during vanadium-bearing titaniferous magnetite smelting.The results show that the thickness of slag skull increases remarkably due to higher content of iron nuggets in vanadium-bearing titaniferous BF slag,which results in decrease of slag skull stability.When the temperature thermocouple measured at the copper cooling stave is kept in the range of 60 ℃ to 80 ℃,the slag skull stability will be improved to maintain safe operation of the copper stave.Under the existing technological conditions,water velocity adjusted from 2.3 m/s to 1.5 m/s has little influence on the slag skull. |
