The invention belongs to the technical field of steel rail production, and discloses a device and method for determining a steel rail pre-bending line and a steel rail pre-bending method. The device for determining the pre-bending line of the steel rail comprises at least one radar scanner, a plurality of laser range finders and a data processing control device, the radar scanners and the laser range finders are arranged on the outlet side of a cooling bed, and the laser range finders are arranged at intervals in the width direction of the cooling bed and arranged in the same straight line perpendicular to the movement direction of the steel rail. The radar scanner is used for obtaining a point cloud data curve when the steel rails move to the outlet side of the cooling bed, and the laser range finders are used for measuring coordinate values of point positions, corresponding to the laser range finders, of the steel rails located on the outlet side of the cooling bed. And the data processing control system is
