摘要

摘要1080上半部分的数学模型 m3无钟炉顶高炉建成。采用离散元法分析了球团质量配比对炉料分布和填料床结构的影响。结果表明,装药的径向偏析受丸粒比的影响:当丸粒比从20%增加到40%时,药堆角度从32.3°减小到27.3°,而药堆底部宽度增加,药堆高度和顶部宽度趋于减小。此外,随着颗粒比例的增加,填充床的孔隙率有降低的趋势。对于1以内的填充床 m处,孔隙率倾向于从边缘到中心减小。

Numerical study on the influence of pellet proportion on burden distribution in blast furnace
ABSTRACT A mathematical model of the upper part of a 1080 m3 bell-less top blast furnace is established. The influence of the mass proportion of pellet on burden distribution and packed bed structure is analysed by the discrete element method. The results show that the radial segregation of the charge is affected by the pellet ratio: when the proportion of pellets increases from 20% to 40%, the angle of the pile decreases from 32.3° to 27.3°, while the bottom width of the pile increases, and the height and top width of the pile tend to decrease. Furthermore, with the increase of the proportion of pellets, the porosity of the packed bed tends to decrease. For the packed bed within 1 m from the furnace wall, the porosity tends to decrease from the edge to the centre.

期刊介绍: Ironmaking & Steelmaking: Processes, Products and Applications monitors international technological advances in the industry with a strong element of engineering and product related material. First class refereed papers from the international iron and steel community cover all stages of the process, from ironmaking and its attendant technologies, through casting and steelmaking, to rolling, forming and delivery of the product, including monitoring, quality assurance and environmental issues. The journal also carries research profiles, features on technological and industry developments and expert reviews on major conferences.
