水钢采用低比例的钒钛矿高炉炼铁，获得含有钒钛等微量元素的铁水，其性质既不同于一般铁水，也不同于高钒钛铁水，为了弄清这些微量元素对转炉炼钢工艺的影响，分析了钒钛钢渣的物相、熔化性，用高频感应炉模拟转炉吹炼过程并结合生产试验得知：1）普通铁水的碳焰温度为1370～1400℃，水钢铁水的碳焰温度为1400～1430℃，比普通铁水高约30℃；2）在较小的供氧速度下，铁水中的钛、硅、锰可与碳分阶段氧化；3）含有TiO2炉渣的发泡能力、储泡能力强于不含TiO2的炉渣，炉渣中的CO反应性气泡使炉渣的发泡更加严重；4）在转炉吹炼前中期，炉渣中过高的FeO、较低的碱度，炉渣中大量的C-FeO反应，以及含有TiO2炉渣的储泡性质，是喷溅的主要原因。
V-Ti-tracing-elements hot metal, which was different from common hot metal and high V-Ti hot metal, was produced using low proportion iron ore involving V-Ti element. In order to know the effect of these trace elements on converter steelmaking process, the phase compositions and melting characters of V-Ti slag were analyzed and the steelmaking process in converter was simulated by high frequency induction furnace. The results show that: 1) carbon flame temperature of general hot metal is 1370-1400℃, carbon flame temperature of Shuigang hot metal is 1400-1430℃ which is 30℃ higher than that of general hot metal; 2) at a small rate of blowing oxygen, Ti,Si,Mn and C in melt can be oxidized one by one; 3) foaming and foam storage capacity of TiO2-bearing slag is larger than that of slag without TiO2, active CO bubbles in slag exacerbate slag foaming; 4) in prior and mid period of converter steelmaking, super high FeO content, relatively low alkalinity and C-FeO reaction in slag and foam storage capacity of TiO2-bearing slag are main reasons for the slopping.
