【摘要】 用碳酸钠吹氧法预处理含钒铁水时,在前期先单独吹氧脱除一部分钛、硅、锰、钒等元素,在后期加入碳酸钠并继续吹氧直到终点,铁水中的磷、硫、钒可同时脱除而且得到水溶性极佳的钠化钒渣。与前期一开始即加入碳酸钠的过程相比较,碳酸钠的消耗量可减少20—30%。更多还原

【Abstract】 During the pretreatment of V-bearing molten pig iron-with top-blo- wing oxygen and top-adding sodium carbonate,it was treated with oxygen alone at the earlier stage of the process to remove a part of Ti,Si,Mn and V,and with adding sodium carbonate at the later stage oxygen blown continueously till P,S,V could be removed simultaneously and extremely well water-soluable sodium vanadate slag was finally achieved.Compared with the process in which the sodium carbonate was added at the starting of the earlier stage,the consumption of sodium carbonate in the present process could decrease about 20—30%.更多还原
