摘　　要：利用三维离散元法对5000m3高炉圆周方向风口回旋区焦炭非均一消耗条件下,炉内固体炉料的速度、应力分布以及炉墙和炉底的受力情况进行了分析.结果发现,炉口料面料层结构、炉料速度和应力以及炉墙炉底受力呈非对称性分布,死焦堆增高,且在其表面存在狭长的滑动粒子带.The solid flow in a 5 000 m^3 blast furnace was studied by a three-dimensional discrete element method from the aspects of velocity, stress distribution, stress acting on the wall and bottom under circumferential non-uniform coke consumption in the raceway. The results show that an asymmetric solid flow forms in the blast furnace, including the asymmetric distributions of burden layer, particle velocity and stress between particles and the asymmetric stress acting on the wall and bottom. It is also found that the height of deadman increases and there is a slipping region near the surface of deadman.
