转炉局域搅拌和混匀效果的水模型实验
Water model study of local stirring and mixing effects of converter
摘要
Abstract
In order to investigate the local and stirring effect of converters,a converter water model whose prototype is a 55 t converter is built.The method of multi‐electrode simultaneous detection is used under different blowing ways.Under pure bottom blowing conditions,the mixing time at the bottom center is relatively short.While,in the condition of top blowing,the weak stirring zone is at the bottom center.In the condition of top‐bottom combined blowing,with the increase of lance height,the mixing time of the position of the 4 measuring points in BOF bath first decrease and then increase.And the bottom nozzles layout is obtained when the average mixing time is the shortest.When the lance height is 0.16 m,the mixing effect is better on the upper and lower part of the sidewall and at the center of circulation;when the lance height is 0.20 m,the mixing time at the bottom center is the shortest.The stirring and mixing effect of the symmetrical and the asymmetrical layout of bottom blowing nozzles is compared,and it’s found the asymmetrical and centralized arrangement is more conductive to improve the flow field of the converter and reduce weak stirring zones.关键词
