Abstract: The imported Consteel carbon-oxygen lance technology at Xining Special Steel has been improved by water model cold simulation test to determine the technical parameters -25 degrees slope angle of jet and angle included between lance at service position and a horizontal plane of furnace bottom to maintain 35～50 degrees. The modified technology improved the temperature field and fluid field of liquid steel in arc furnace,decreased the etch of bottom and gate of furnace and intensified the whirl of surface of liquid steel. The application results showed that the heat number of steelmaking by each lance was up to 486 heats,the life of arc furnace wall increased by 28 heats,tap to tap time decreased by 8 min.
