提高高炉氧─煤喷吹效益瑞典钢铁公司与北欧国家冶金研究基金会一起，对世界各国的喷煤技术进行了调研，以找出最适于本公司的工艺方法。结论是，若采用低于３％的富氧率，伴之尽可能高的喷煤率（约２００Ｋｇ／ｔ铁），将会取得最佳的效益。据此，研制了一种中心通过煤粉... Boosting Blast Furnace Oxygen-Injection Efficiency Together with the Nordic National Metallurgical Research Foundation, Swedish Iron and Steel Company conducted a survey of coal injection technologies in various countries in the world to find the most suitable process for the Company. The conclusion is that if the rate of oxygen enrichment of less than 3% is combined with the highest possible rate of coal injection (about 200 kg / t iron), the best benefit will be achieved. Accordingly, developed a center through the pulverized coal ...
