新中国成立以来,我国一直致力于发展钢铁工业,并取得了举世瞩目的成就。1949年,我国只能生产15.82万吨钢,居世界第26位。经过恢复和发展,1978年突破3000万吨钢,达3178万吨,居世界第5位。在1979年～2001年改革开放的22年中,钢和钢材的产量持续、快速增长。1996年钢产量突破1亿吨,跃居世界第1位。经过长期高速发展,中国在吨位上已成为钢铁大国,这与我国结合关键技术进行技术创新是分不开的。首先是产品的品种有了扩大。50
Since the founding of new China, our country has been devoted to developing the steel industry and has made remarkable achievements. In 1949, China could only produce 158,200 tons of steel, ranking the 26th in the world. After recovery and development, in 1978, it exceeded 30 million tons of steel to 31.78 million tons, ranking the fifth in the world. During the 22 years of reform and opening up from 1979 to 2001, the output of steel and steel continued to grow rapidly. In 1996, the output of steel exceeded 100 million tons, ranking No.1 in the world. After long-term rapid development, China has become a steel power in the tonnage. This is inseparable from our country’s technological innovation combined with key technologies. The first is the product variety has been expanded. 50
