Method for predicting carbon content in vanadium-nitrogen alloy

The invention relates to a method for predicting the carbon content in a vanadium-nitrogen alloy, which comprises the following steps: constructing a prediction model Y = (A-X) 2/B, Y being the carbon-oxygen product in the vanadium-nitrogen alloy, A and B being constants, and X being the nitrogen content in the vanadium-nitrogen alloy; detecting the nitrogen content of the vanadium-nitrogen alloy to obtain the nitrogen content, and detecting the oxygen content of the vanadium-nitrogen alloy to obtain the oxygen content; and obtaining a Y value according to the constructed prediction model and the obtained nitrogen content, and then dividing the Y value by the obtained oxygen content to obtain a predicted value of the carbon content in the vanadium-nitrogen alloy. According to the method, the prediction model capable of predicting the carbon content in the vanadium-nitrogen alloy product is constructed, and the method has high self-adaptability; according to the method, the carbon content prediction result can
