国民经济的发展要求冶金工业供给大量金属,解决此任务的主要道路是建设近代化的大规模的冶金车间,但是这却需要相当大的资金,特别是需要相当长的时间,因此为了迅速提高钢的产量,如何强化冶炼过程提高现有炉子的产量便有着非常重要的意义。 近年来苏联以及其他国家采用了一些新技术,已经有成效地使得平炉的生产率大为增加。这些新按术如平炉用氧,火焰增碳以及使用新的耐火材料等等。我国重工业部去 The development of the national economy requires the metallurgical industry to supply a large amount of metal. The main way to solve this task is to build a modern large-scale metallurgical workshop, but this requires considerable capital, in particular, considerable time. Therefore, in order to rapidly increase the output of steel Of the output, how to strengthen the smelting process to increase the output of existing stoves have a very important significance. In recent years, the Soviet Union and other countries have adopted some new technologies and have effectively brought the productivity of flat hearth furnaces significantly higher. These new techniques, such as open hearth oxygen, carbon flame and the use of new refractory materials and so on. China’s Ministry of Heavy Industry to go
