2 Rails Wuhan Iron and Steel Co., Ltd. has produced rails for nearly 40 years and is one of the four major manufacturers of rails in China. It can produce common rails as per Railway Standards TB/T2344 and National Standard GB2585. It can also produce high-speed rails as per High-speed Passenger Rail Line Standards by the Ministry of Railways with speeds of 250 km / h and 350 km / h. The maximum length of a single rail can be as long as 100 meters. At the same time, can produce rails as per EN, BS, UIC and other foreign standards to meet the needs of the international market.

3 The section steel production line of Heavy Section Mill of WISCO, Ltd has an annual capacity of 1.05 million tons. The main production equipment and process are at the world first level. Key equipment adopts the world most advanced control technology and hardware configuration, and equipped with instrumentation, measuring equipment and technology at world technical cutting edge. In which, the high-speed universal section mill and edging mill are the newest generation of products of SMS-MEER Company, Germany, characterized by their compact construction and high rolling accuracy. Its products have reached world leading level in regard to comprehensive quality. Dec. 27th 2008, the 100-meter length-fixed rails of 60kg/m U71Mn (K) and U75V for speed of 350 km/h produced by WISCO passed technological review of Transport Bureau of Ministry of Railways.

9 Product Features, Functions & Cautions Main Features Wuhan Iron and Steel Co., Ltd. produces all types of its rails on basis of selfmade blank. It uses top and bottom combined blown converter to refine steel, with world's leading secondary refining facilities for hot metal pretreatment, such as ladle furnace (LF) which can reduce inclusions and purify steel; RH vacuum furnace which can ensure the content of hydrogen 1.5PPM; the full protection casting and soft reduction technology for continuous casting which can guarantee the purity of steel, the stability in the composition of billets, the homogeneity of structure and the defect-free surface. There are various billet sections to meet the demands of rails at different levels. Main Functions Cautions 38kg/m rails are mainly for forestry transport, 43kg/m rails are mainly for coal transport, 50kg/m and 60kg/m rails are for railway lines and high-speed railway lines, BS75A, BS75R, BS90A, UIC54 rails are exported for passenger and cargo transport. QU80, QU100 rails are for crane rails. In order not to bend the rails or cause internal cracks by falling, it is required to load and land cargos gently during hoisting. It is strictly prohibited to cut rails with flame lance.
