Pa) and oxygen lance level ( 1.2-1.5 m) on jet characteristics and impact of liquid surface of 100 t top-blown oxygen converter at steel words is studied by using Fluent fluid software and standard k-e turbulence model. Results show that with increasing oxygen pressure the high speed region of oxygen in converter enlarges
the length of jet key area increases and the pressure energy of jet enhances ; with oxygen pressure 11.46 x 10
5
Pa
as oxygen lance level is raised from 1.2 m to 1.5 m
the max impact speed of oxygen flow at liquid surface decreases from 240 m/s to 194 m/s and the high speed region reduces
the depth of liquid cavity decreases from 0.37-0.43 m to 0.30-0.36 m while the max diameter of liquid cavity enlarges from 0.70-0.80 m to
