摘要: 利用三維離散元法對5000 m³高爐圓周方向風口回旋區焦炭非均一消耗條件下,爐內固體爐料的速度、應力分布以及爐墻和爐底的受力情況進行了分析.結果發現,爐口料面料層結構、爐料速度和應力以及爐墻爐底受力呈非對稱性分布,死焦堆增高,且在其表面存在狹長的滑動粒子帶.

Abstract: The solid flow in a 5 000 m³ 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.
