Product Features, Functions & Cautions

Main Features

Wuhan Iron and Steel Co., Ltd. produces all types of its rails on basis of self-made 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

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.

CautionsIn 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.
