Abstract:
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.
