【摘要】 钠盐处理含钒铁水以直接提钒,对某些钢铁厂来说,具有很大的吸引力。以氧为载体,喷吹钠盐处理含钒铁水,具有技术先进,工艺简单易行,钠盐利用率高等特点;处理后的低硫、磷纯净铁水,为无渣或少渣炼钢提供了基础条件。本试验中,对喷吹设备和喷吹工艺条件进行了研究,在钠盐、供氧量等适宜条件下,可取得钒脱除率≥85％,硫、磷脱除率≥90％的良好结果;钠化钒渣中钒的转化率十分理想,一般大于95％。更多还原

【Abstract】 The soda treatment on V-containing hot metal to extract vanadium is of great concern tosome iron and steel plants.The treatment on hot metal by injecting soda with oxygen as carriergas is advantageous to simplicity and high utilization rate of soda.After treatment the pure hotmetal with low sulphur and phosphorus can be used as raw material for non-slag or less slagsteelmaking. In this experiment,the injection equipment and process conditions were investigated.Underproper soda and oxygen consumption rate,a good result can be achieved:removal rate of vanadiumis more than 85%;desulphurization and dephosphorization rate are more than 90%;vanadium lea-ching rate from the V-containing slag is quite high and generally more than 95%.更多还原
