Ring height is controlled in a closed-pass radial rolling or by using a pair of identical conical rolls. Pair of guide rolls which is usually controlled by a linkage mechanism keeps the ring central and maintain circularity. Fig. 1 shows the main components of a typical radial–axial ring rolling mill.

RING MILL world leader for more than 40 years. Ring Mill - founded in 1978 - is a leader in the production of forged and rolled products in steel and other alloys. For more than four decades we have been producing to the customer’s specifi ions providing custom pieces especially in the Oil and Gas Pipes and Fittings and Power Generation fields.
Radial-axial ring rolling is a hot forming process e.g. for cranes or wind mills Ring-rolling is usually significantly faster than open-die or closed-die forging and this is the key
8000mm Radial and Axial Ring Rolling Mill. LS Heavy Industry Engineering Co. Ltd. ring rolling mills are used where the diameter of the blanks needs to be increased in order to produce rings. For this the blanks are heated to forging temperature and their wall thickness reduced during radial ring rolling by a main roll and a mandrel roll.
The plastic penetration condition and biting-in condition of a radial conical ring rolling process with a closed die structure on the top and bottom of driven roll simplified as RCRRCDS were established. The reasonable value range of mandrel feed rate in rolling process was deduced. A coupled thermomechanical 3D FE model of RCRRCDS process was established.

Our ingenuity enables us to open die forge parts with geometries others find difficult such as tall sleeves flat washers and short bar forgings. Forged rings created on our Wagner 63/63 radial/axial ring rolling mill are very cost effective for orders that range from a single one-of-a-kind workpiece to large volumes.
Closed die forging presents a dangerous working environment . Appli ion. Closed die forging and open die casting are the most common used forging methods for steel parts. Forging is popular because of its improved internal grain structure and can produce stronger and tougher products.
Benefits of Seamless Rolled Ring Forgings. The open die forging process removes structural defects as well as porosity and aligns the grain flow in the preform workpiece. The rolling process itself creates rings with improved concentricity and smoothness. Furthermore ring forgings that have been created in rolling mills are more cost effective.
Ring rolling is an established method to produce seamless rings of different cross-sectional geometries. For dish shaped rings there are appli ions in different areas such as offshore aeronautics or the energy sector. At the moment dish shaped rings are produced by machining of rings with rectangular shaped cross section by open die hollow forging on a conical mandrel or by using
Seamless Rolled Ring Forging Process. The production of seamless forged rings is often performed by a process called ring rolling on rolling mills. These mills vary in size to produce forged rings with outside diameters of just a few inches to over 300 inches and in weights from a single pound up to over 300000 pounds.
Axial closed-die rolling machines Axial closed-die rolling is ideal for many appli ions. You can use it to roll virtually all rotationally symmetrical workpieces from any forgeable material. Included here are not only axle drive wheels but also aluminum wheels.
