【摘要】：正釩鐵主要用作煉鋼的合金添加劑,鋼中加入釩鐵后,可以顯著提高鋼的硬度、強(qiáng)度、耐磨度及延展性,改善鋼的切削性能。隨著對冶煉新鋼種品質(zhì)要求的提高,對冶煉過程中使用的原材料中微量元素的控制也日趨嚴(yán)格�？焖俣_地測定釩鐵中微量元素的含量,更加準(zhǔn)確地控制冶煉則顯得日益重要。目前釩鐵中微量元素測定方法主要有硫酸脫水
[Abstract]:Ferrovanadium is mainly used as alloy additive for steelmaking. After adding ferrovanadium to the steel, the hardness, strength, wear resistance and extensibility of the steel can be significantly improved, and the cutting performance of the steel can be improved. With the improvement of the quality requirements of smelting new steel, the control of trace elements in raw materials used in smelting process is becoming more and more strict. It is increasingly important to determine the content of trace elements in ferrovanadium quickly and accurately and to control smelting more accurately. At present, the main determination methods of trace elements in ferrovanadium are sulfuric acid dehydration.
