According to the technical scheme of the horizontal blank ejection device, the design of rotatable integrated type pinch rolls is adopted; guide rolls and the pinch rolls are fixed to a frame; the frame can rotate by 90 degrees around a rotation shaft in the middle; when the frame is in a vertical position, the blank drawing function is achieved; when the frame is in a horizontal position, the spindle rod threading function or casting blank output function is achieved. The horizontal blank ejection device comprises the frame, the guide rolls, the pinch rolls, the rotation shaft and a rotation mechanism. The frame is a rectangular steel structure frame. The multiple guide rolls are uniformly distributed along the frame. The pinch rolls are installed on the front portion of the frame. The axial directions of the guide rolls and the pinch rolls are perpendicular to the length direction of the frame. The rotation shaft is installed in the middle of the frame. The rotation mechanism is connected with the frame.
