TBM法由西德蒂森钢公司转炉钢厂开发的炼钢工艺,其特点是搅拌气体通过炉底吹入熔池内,而氧气仍是通过氧枪从上部吹到熔池上面的,其底部喷嘴的数目、布置及内径要根据转炉的几何形状和吹炼要求而定,搅拌气压力取决于喷嘴直径、熔池高度和所要求的搅拌强度,每个喷嘴的气体吹入量可单独或一起调节,同时可根 TBM method developed by West Desso Steel Company converter steelmaking process, which is characterized by stirring gas blowing through the bottom into the molten pool, and oxygen is still from the top through the oxygen lance to the molten pool above the bottom of the nozzle The number, arrangement and inner diameter depend on the converter geometry and blowing requirements. The agitation pressure depends on the nozzle diameter, bath height, and required agitation. The amount of gas in each nozzle can be adjusted separately or together , At the same time can be root
