NUMERICAL COMPUTATION OF MIXING PROCESSES IN BATH OF BOTTOM STIRRING ELECTRIC ARC FURNACE
底吹电弧炉熔池混合过程的模拟研究

The flow field and the mixing time in the water model of the bath of bottom stirring electric arc furnace(EAF) for single-and multi-plug are numerically and experimentally studied. The mixing time is the function of the diameter, number, location of plugs and the tracer injection situation. It was shown that the variation of mixing time is not obvious with the increasing of plug diameter, the stirring efficiency is better if plug number is increased and plugs are distributed in deep and off-central region in vessel, since the angular velocities occur and the more stirring power is obtained in these layouts.
