Cold Condition

By oxygen lance measuring system, under the normal temperature (cold condition) systematic study is carried on traditional supersonic jet flow field that is simulated by compressed-air and on coherent jet flow flied which is accompanied by low density helium in this paper, By commercial software FLUENT, associated with experimental data, the standard double equation K- model is revised appropriately with C1=1.45，C2=1.88. The behavior of axis symmetric jet can be predicted better by simulated results. The flow state of traditional supersonic jet and the characteristic of coherent jet flow flied under vice-hole helium low density concomitance situation are analyzed systematically.

This paper compares the structure and basic points of the new lance with traditional ones, analyses the new design with center hole in head in fields of theoretical supersonic jet characteristics including penetrating depth and stirring energy, operation mode in smelting process and. The application results show its advantages in keeping whole dephosphorizing rate, final carbon-oxygen equilibrium control of steel and cost reducing, on the other hand, point to its several drawbacks. Optimize solutions are introduced at the end.
