Abstract

The invention discloses a production line of special section wing rail and a manufacturing method thereof. The production line comprises a cogging mill and a universal machine set, and is characterized in that the cogging mill comprises an asymmetrical caliber which leads a working edge of a railhead of the special section wing rail is arranged toward the direction below a rolling line, support platforms are mounted on an upper guide and a lower guide at an outlet side of a second edger and a universal finishing mill of the universal machine set to control tapping torque. By adopting the invention, the problems such as reversing, bending and the like caused by uneven deformation due to the asymmetrical section of the special section wing rail can be effectively controlled, and the specialsection wing rail with a 75m length can be manufactured, which has stable product quality and can satisfy the requirement of high-speed railway construction.

Description

technical field [0001] The invention relates to the field of production of wing rails with special sections, in particular to a production line for producing wing rails with special sections through a universal rolling mill production system and a manufacturing method thereof. Background technique [0002] Special-section wing rails are mainly matched with 60D40 rails to produce high-speed railway turnouts with a speed of 250 kilometers per hour and above. The special-section wing rails currently in use are manufactured by the method of "forging + welding" (referred to as "forging and welding special-section wing rails"). Due to the poor quality stability of forged and welded wing rails with special sections, the shape needs to be guaranteed by a large amount of machining, and the production efficiency is low. In addition, the length of the forged special section wing rails is short, requiring multiple welds, and the quality and flatness of the welds cannot be achieved. The h...
