Ring forgings are widely used in many industrial fields because of their excellent mechanical prop-erties.Ring forging is a kind of heavy industry parts which involves many materials,large quantity and wide area.Because the ring forging is often in a long working time,high temperature,high pressure,high speed,high and low frequency vibration of the combined effect of the harsh environment,so the quality and size of the forging requirements are very harsh,which puts forward higher requirements for the forging process of the ring forging,ring forging technology has also been rapidly developed.This paper takes an automatic precision ring forging rolling production line produced by Tianduan Company as an example,combined with the pro-duction process of shaped section ring forging,focuses on the core equipment and its functional characteristics in the production line,and provides a certain reference significance for the technical key points and develop-ment direction of this kind of ring forging and rolling production line.
