国外碳素工业的发展,从1808年英国H·Davy 发明电池用碳棒以来,迄今已有一百七十余年的历史。目前,世界上有20几个国家能生产石墨电极,主要有英、日、美、法、西德和苏联。据资料报导,1970年全世界石墨电极的总产量约为742,330吨。美国是世界碳素工业最发达的国家,它所拥有的挤压设备不论在技术上,还是能力上都较先进。早在1913年,美国便开 The development of foreign carbon industry, since 1808 British H. Davy invented the battery carbon rod, so far has been more than 170 years of history. At present, there are more than 20 countries in the world that can produce graphite electrodes, mainly Britain, Japan, the United States, France, West Germany and the Soviet Union. According to data, the total output of graphite electrodes worldwide was approximately 742,330 tons in 1970. The United States is the most advanced country in the world’s carbon industry. The extrusion equipment it possesses is technologically advanced and capable. As early as 1913, the United States opened
