What is obtained with the forging waste heat normalizing and controlled cooling technique is the coarse stable structure in a 20CrMnTi gear, but its cutability is good.
In the course of metal forging press, wiredraw, rolling and honing, using this lubricant can improve the product quality, reduce the energy consumption and enhance the productivity.
In June1957, forging and coldworking workshops equipped with metal processing capability were established, and the plant began to repair and build barge, repair steamer steering gear and windlass.
