重轨 目前我国铁路部门每年消费钢材400多万吨,其中年消费重轨128万吨。铁路年营运里程5.3万公里,预计2000年将达到7万公里。按今后平均每年增加2400—2500公里新线(包括新建部分高速铁路).再加上建设专用线、复线和老线维修改造等需要,到2000年,需重轨180万吨左右,其中,60公斤重轨的使用比例将达到60％以上。
Heavy Rail At present, China’s railway sector consumes more than 4 million tons of steel each year, of which 1.28 million tons are consumed annually. The railway has a mileage of 53,000 kilometers and is expected to reach 70,000 kilometers in 2000. In the future, an average of 2,400-25,500 km of new lines will be added each year (including the construction of some new high-speed lines). Coupled with the needs of special lines for construction, double-line maintenance and renovation of old lines, by the year of 2000, about 1,800,000 tons of heavy rail will be required. Kg heavy rail will use more than 60%.
