Steel rails' joint fishplate made of xy30 steel

Abstract

The present invention relates to a rail clip, an important fitting part, for the railway made of a new steel XY30 which is one of a high-manganese steel without nickel and which has high strength and high toughness even if it is used in the low-temperature circumstance. The rail clip is characterized in that the rail clip has the shape of a bar with a section of “T” and comprises a working surface, a non-working surface, a mounting surface for bolts and a non-working surface inside a web plate; the two working surfaces of a upper small surface side and a lower large surface side on the same side of the rail clip come into circular arc point contact with the railroad rail, a small circular arc is provided on the working surface which is on the upper small surface side; the upper small surface side, the lower large surface side and the non-working surface inside the web plate are connected with circular arcs; upper and lower non-working surfaces on the other side of the rail clip are perpendicular to the horizon.
