RAIL PRODUCING METHOD AND PRODUCING EQUIPMENT |
摘要 |
The present invention provides a method and equipment for producing a rail, the method and equipment being capable of lowering a bend at an end of a rail effectively and the truncation amount thereof. The present invention is a method for producing a rail, characterized by: cooling a hot-rolled mother rail to an ordinary temperature substantially while the length thereof after the hot rolling is maintained; and thereafter cutting the mother rail simultaneously in a predetermined length with at least three cold-sawing machines. Further, the present invention is equipment for producing a rail, characterized by equipped with: a transfer bed capable of moving a mother rail cooled to an ordinary temperature substantially while the length thereof after hot rolling is maintained in the rolling direction and/or in the direction perpendicular to the rolling direction; and at least three cold-sawing machines disposed in parallel with each other on said transfer bed. <IMAGE> |
