Rolling roller set system for rolling waste railway steel rails

The invention relates to the technical field of waste steel rail recycling and processing, and discloses a rolling roller set system for rolling waste railway steel rails, which comprises a mounting table, a supporting frame is fixedly connected to the top of the mounting table, a plurality of supporting rollers are rotatably connected in the supporting frame, a mounting frame is fixedly connected to the mounting table, and the supporting rollers are rotatably connected in the mounting frame. According to the rolling roller set system for rolling the waste railway steel rails, the transmission mechanism drives the lifting threaded rod to rotate, the lifting threaded rod drives the rolling rollers to move up and down to be adjusted, and then through cooperation of the supporting rollers, the rolling rollers can move up and down to be adjusted; and therefore, the cut steel rail plate is subjected to uniform extension type rolling, so that the steel rail plate is a plate with uniform thickness, and the quality o
