Nitrogen Control Technology for the Blowing Process of Combined Blowing Converter

Abstract:

At present, the nitrogen content in aimed molten steel is 18.32ppm on average in PISCO（Panzhihua Iron & Steel Co.）, and there is big fluctuation for nitrogen content. To solve this problem, factors affected the nitrogen content while blowing is discussed, and a comprehensive nitrogen control technology is formed. Experimental results show that with this technology the nitrogen content in aimed molten steel can be controlled in 15ppm, with the average value is 12.53ppm. The average nitrogen content in aimed molten steel is reduced by 5.79ppm, and nitrogen content of aimed molten steel is well controlled.
