简要介绍了VN合金在F35MnVN钢中的应用 ,对钒、氮的作用和钢水增氮方法进行了研究。结果表明 ,为发挥钒的作用 ,应增加含钒非调质钢中氮的含量 ;加氮的最好办法是采用VN合金。
The application of VN alloy in F35MnVN steel is briefly introduced, the effect of vanadium and nitrogen and the method of increasing nitrogen in molten steel are studied. The results show that, in order to play the role of vanadium, the content of nitrogen in non-quenched and tempered steel containing vanadium should be increased; the best way to add nitrogen is to use VN alloy.
