Analysis and Practical Application of Extracting Vanadium from Hot Metal in Steel Ladle

The thermodynamics and kinetics factors about ladle vanadium extraction are introduced firstly. According to the real production in the resources comprehensive utilization test pilot of Pangang, the causes of temperature controlling, shortage of oxygen supply as well as the difficult for slag skimming are all analyzed in detail and the solutions are put forward at the same time. Under the real production conditions, if controlling the temperature of molten pool between 1450 similar to 1500 degrees C,keeping the bottom blowing smoothly, meeting the oxygen supply of 1400 Nm3/h and adding adequate coolant at better time it will get good vanadium extraction results.
