去年,中国生產了四十六百万吨钢,产量仅低于苏联、日本和美国,在全世界已跃居第四位。一九八五年中国一天的钢产量就接近于一九四九年全年的產量,那時年產量為十五萬八千吨,位居世界第二十六位。钢材開始出口新中國成立之初,鋼材品種甚少,甚至连釘子都不能自給,要大量使用‘洋釘’。現在,製造汽車、輪船、飛机所需的鋼材,都能生產,國防工業和尖端技術,包括原子彈、氫彈、导彈、核潛艇、火箭和通信衛星所需的金屬材料也基本上立足國內。中國生產的造船板已經國際船級社認可,用中国钢板製成的遠洋輪船已有多艘出口。輪箍、細紋钢等在東南亞及香港地區都有較好聲譽。不過,由於國內鋼材需求 Last year, China produced 46 million tons of steel, only less than the output of the Soviet Union, Japan and the United States, ranking the fourth in the world. In 1985, China’s steel output a day was close to that of the full year 1949, when the annual output was 158,000 tons, ranking the 26th in the world. Steel began to be exported At the beginning of the founding of New China, there were very few varieties of steel. Even the nails were not self-sufficient. Therefore, it is necessary to extensively use the ’nails’. Now, the steel needed to make automobiles, ships and aircraft can be produced. The national defense industry and cutting-edge technologies, including the metal materials needed for atomic bombs, hydrogen bombs, missiles, nuclear submarines, rockets and communications satellites, are basically still at home. Shipbuilding plates made in China have been approved by the International Classification Society, and many ocean-going vessels made with Chinese steel plates have been exported. Wheels, fine steel, etc. in Southeast Asia and Hong Kong have a better reputation. However, due to the domestic steel demand
