The essence of ring rolling is to carry out radial rolling, but it also needs to make blank and is similar with forging, in fact, it is the second making blank. Ring rolling is not the same with rolling, and is also different from forging, it has much economic and technical advantages to the forming of rings.

   The features of ring rolling are as follows:

   1、Only to need light-duty equipment

Ring rolling is punching forming to the partial blank continuously by rotating mould, compared with the complete punching forming for stamp forging, it has
small area of contact between the tool and workpiece, and also has small deforming force. So, it can make biggish rings by adopting light-duty equipment, which can enlarge the range of forming for rings.

   2、High material utilization

   Compared with stamp forging, making blank of ring rolling only needs to punch small hole, so it has small punching recess, and also have not flash and pattern draft which is necessary for stamp forging, the shape of sectional dimension for rings close to products, so it can reduce cutting capacity and also save raw material.

   3、Excellent inner quality

   Ring rolling deformation adopts radial compression and circumference extension type，the metal fibre of ring arrange continuously along the circle, which is frequently in accordance with the force and abrasion. So, ring rolling products have high intensity and wearability and super inner quality.

   4、Excellent labor condition

   Compared with ordinary forging, ring rolling has not impact , and also has small vibration and noise, which greatly improve the labour condition and easy to realize mechanize and automation.

   5、High production efficiency

    Compared with ordinary forging(e.g. reaming), it is much faster for ring rolling, which can greatly improve the production efficiency.
