Modern Ring

Aug 08, 2019In a ring-rolling simulation on a double-stand mill, for example, the motion of the mandrel and axial rolls can be set up in any number of ways. Their control can be dependent on a traditional lamination curve; by the velocity of the mandrel and axial rolls; by the circular motion of the mandrel; or defined as a universal drive that can have Get price

Ring Forging

While impression or closed die forging confines the metal in dies, open die forging is distinguished by the fact that the metal is never completely confined or restrained in the dies. Most open die forgings are produced on flat dies. The production of seamless forged rings is often performed by a process called ring rolling on rolling mills Get price

Manufacturing dish shaped rings on radial

Jul 13, 2013Ring rolling is an established method to produce seamless rings of different cross-sectional geometries. For dish shaped rings, there are applications 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 Get price

The influence of constraint rolls on temperature evolution

Aug 01, 2020In radial-axial ring rolling, the ring is generally horizontal, and is additionally contacted by two conical rolls which control the axial growth and profile of the ring. In either of the above processes, the ring may be influenced by one or two controlled 'guide rolls' which are moved under closed-loop control with the aim of delivering a Get price

Intended Dishing in Ring Rolling

Ring Rolling is a versatile metal-forming process to manufacture seamless rings of various cross-sectional geometries. Rings with a "dish shape" are used in different areas such as offshore, aeronautics or the energy sector. Current ways to produce dish shaped rings have the disadvantages of limited or inflexible geometries and either high material waste, additional costs for special tools Get price

Improvement of the dishing process in ring rolling using

Nov 26, 2016Thus, the goal of this investigation is to improve the geometrical accuracy of dish shaped rings produced on conventional radial-axial ring rolling mills by replacing the lower cylindrical part of the guide rolls by a conical module. Using this improved rolling strategy, the dishing angle deviation was reduced from 5 to 1. Get price

More roller bearing types

Supporting, idler rollers, press and track rollers are roller bearing types whose special feature is a thick-walled outer ring. This outer ring is not installed in a hole as in other bearings, but it runs directly on one tier, a curved track or e.g. backs against a roll in straightening machines. These bearings can transmit high and jerky forces. Get price
