Dephosphorization in the ladle is a new type of dephosphorization method. The water simulation experiment of semi-steel dephosphorization in 100t ladle of Chengde steel has been carried out.The best mixing time has been investigated for various process parameters of blowing oxygen lance and bottom blowing.It turns out to be that the best location of the pure bottom blowing is 0.7R-120 Â°,the best bottom blowing flow rate is 100L/min;and the best of the top bottom blowing rate is 3000 Nm3/h,top gun angle is 60Â°, top lance height is 500mm.The order of three elements on influencing the mixing time is as follows:Top blowing flow >top gun height > top gun angle.The average of dephosphorus efficiency is 51.8% in industrial experiments.
