据统计,1978年世界上平炉钢的产量为17700万吨,1979年变化不大,至少为17500万吨,占总产量的23％。苏联仍是世界上平炉最多的国家,产量约9200万吨;其次是美国,为1900万吨;欧洲共同体900万吨;东欧各国以波兰的平炉钢最多,约1000万吨;捷克、东德、罗马尼亚平炉钢比例均在40％以上。我国是平炉较多的国家之一,全国共有平炉77座。容量为300~500吨平炉34座,100~300吨平炉18座,小于100吨平炉25座。总生产能力约为1400万吨,产量占世界第三位。如何发挥现有平炉的作用,是许多国家所共同关心的问题。从炼钢技术发展的规律看,用现代化的大型氧气转炉取代平炉是无
According to statistics, the output of flat-rolled steel in the world in 1978 was 177 million tons, little change in 1979, at least 175 million tons, accounting for 23% of the total output. The Soviet Union is still the world’s largest open hearth furnace with a production volume of 92 million tons, followed by the United States at 19 million tons, the European Community at 9 million tons, Poland’s flat furnace steel at most in Eastern Europe at about 10 million tons, the Czech Republic, East Germany, Romanian open hearth steel ratio is above 40%. China is one of the more open hearth furnace, a total of flat furnace 77. Capacity of 300 ~ 500 tons open hearth 34, 100 ~ 300 tons open hearth 18, less than 100 tons of hearth 25. The total production capacity of about 14 million tons, the output of third in the world. How to play the role of the existing open hearth is a common concern in many countries. From the rule of the development of steelmaking technology, the use of modern large-scale oxygen furnace to replace the hearth is none
