2、 ABSTRACTIIABSTRACTOxygen supply system is the central link to control the converter of vanadium extraction, the system includes the lance position, the nozzle structure, oxygen consumption, oxygen

3、 supply intensity, oxygen pressure and other parameters. The main products of the converter of vanadium extraction are steel and vanadium slag, through the design of oxygen supply system to meet the requirements of the c

4、arbon content of the steel and the temperature of vanadium extraction in the converter, the vanadium is oxidized into the vanadium slag as much as possible for increasing vanadium oxidation rate. At the same time, reduci

5、ng the vanadium content which exist in the semi steel ,.The main content of this paper is to design the oxygen supply system of 130 tons of vanadium extraction converter. The main contents include analysing the performan

6、ce of the vanadium slag, the calculation of material balance and heat balance in the converter, design the oxygen consumption of per ton hot metal, the calculation of the total oxygen supply, selecting the figure of Mahe

7、r number in the nozzle exit, the design of the throat diameter, the design about the position of the oxygen lance.The design parameters: the amount of oxygen is 282.84 m3, the design oxygen pressure is 0.793 MPa, the oxy

8、gen consumption of per ton hot metal is 15.23 m3/t, throat diameter 40 mm, the nozzle exit Mach number is 2.0, the jet expansion segment of the expansion angle is 11 °,the expansion of the length is 69 mm, the posit
