| description | As an advanced nozzle and because of protective gas around the main oxygen hole, coherent jet oxygen lance can make the jet concentrated with higher kinetic energy. In this paper, a coherent jet oxygen lance is tried to be made with small oxygen holes around the main oxygen hole on the traditional oxygen lance. Flow characteristic of coherent jet oxygen lance and traditional oxygen lance are simulated by CFD software. The results show that, compared with traditional oxygen lance, the attenuation of coherent jet oxygen lance is slow on the center axis, impact depth is deep, the liquid region velocity is high in the center of molten pools, flow ability of liquid steel is good in molten pools. Coherent jet oxygen lance with the suitable lance height can replace traditional top-bottom blowing mode. |
