The invention relates to a forging method capable of reducing curvature of slender steel, and belongs to the technical field of steel forging. In order to solve the problem that a precision forging machine is liable to generate bending during slender steel forging, the invention provides the forging method capable of reducing the curvature of the slender steel. A deformation way of alternating forging passes and no-load passes in a precision forging process is adopted, an initial-stage forging pass adopt a regular forging method, the last two forging passes start to forge one end of a materialfrom the middle position, with certain distance from the end head of the material, return to the middle position with no load and forge to the other end of the material from the position. Structuralstress and deformation stress generated during forging are released through the no-load passes, so that the stress is prevented from being focused to generate bending; and the last two forging passesadopt pulling and punching to reduce bending caused by impact generated by the material and the edge of a hammer head in a pushing-in process, so that linearity of a slender rod or square steel forgedby the precision forging machine is effectively controlled, and a qualification rate of the product is increased.
