According to real production situation of an 180 t top and bottom combined blown converter at Anshan Steel
a supersonic jet oxygen lance has been designed to carry out water modeling test
in order to avoid the problem of revising lance position which is caused by subsonic jet oxygen lance. The test was carried out by 10:1 water model with insuring constant optimum bottom blown process parameter (4 hole symmetry
bottom blowing flowing rate 0.70 m

/h)
changing flowing rate (38~42 m

/h) and lance blowing position ( 130~210 mm) of top lance. Results showed that optimum process parameters for water model were lance position 150 mm and flowing rate 39 m
