Abstract

Based on 300 t top-bottom combined blowing converter bottom air brick location layout problems, ANSYS Fluent software is adopted to establish the three-dimensional model, which simulated the change after the location of the four air brick at the bottom of the flow of molten steel in the converter. The results show that when the bottom blow flow is constant, the four bottom permeable bricks should adopt asymmetric staggered layout, which is beneficial to uniform converter flow field. At the same time, it was found that the angle of the bottom-blown gas supply element is different and the influence on the wall scour is different. When the position of the bottom blown air brick is determined, the inclination angle of the air supply element is 10°, the molten steel has relatively less erosion on the furnace wall of the converter, the flow field in the converter is more reasonable, and the cost is saved for the converter smelting.
