On-Site Speaker (Planned) Sikun Peng
Abstract Scope In this paper, the effects of the side hole area, shape and angle of the submerged nozzle on the liquid level fluctuation, impact depth, slag layer thickness and slag entrapment times of molten steel in slab mold were studied by combining mathematical simulation with physical simulation. The results show that with the increase of side hole area, the fluctuation degree of liquid level in the mold decreases, the impact depth decreases, and the thickness difference of liquid slag layer increases; With the change of side hole shape from rectangle to ellipse, the fluctuation degree of liquid level, impact depth and thickness difference of liquid slag layer decrease,; With the increase of side hole angle, the fluctuation degree of molten steel level in the mold decreases, the impact depth increases, and the thickness difference of liquid slag layer increases,. The research results can provide a theoretical basis for the design of reasonable mold nozzle.
