摘　　要：通过水模试验的方法测量了转炉双联法在不同喷吹条件下熔池运动的基本参数。试验结果表明,脱磷炉底吹供气强度超过0.30m3/(t·min)时,增加供气量对缩短混匀时间作用不明显。熔池中有10%(质量分数)废钢时,混匀时间平均延长63%。用高供氧强度吹炼(5m3/(t·min)),脱碳的喷溅率比正常供氧量有很大提高。采用喷孔交错布置喷头和适当加大炉容比可以降低喷溅率。The basic parameters of bath flow were simulated by water model under different blowing conditions of oxygen lance nozzle and conditions of duplex process. The results show that the effect of increasing blowing on shortening mixing time is not obvious when the strength of bottom blowing gas of dephosphorization reached 0.30m3/（t·min）. The mixing time is extended 63% when there is 10% scrap. Decarburization with high strength oxygen supply（5m3/（t·min））, the splashing ratio can be greatly improved than with normal strength oxygen supply. The splashing ratio is reduced when the holes arranged interlaced nozzle was adopted and the ratio of converter capacity was increased.
