Ring Rolling of metals: What it is

The Ring Rolling process is a machining method in which a very thick ring, placed between two groups of rollers, is deformed in a ring with a greater diameter and smaller section. The thickness is reduced by approaching the rings while rotating. The main products made are large sealing rings for turbines and for bearings with very low tolerances and a favourable arrangement of grains thus improving the mechanical properties.

Ring Rolling Simulation: How it works

Simulation of ring rolling to preview times and forces required to make the ring.

The Ring Rolling system of DEFORM was specifically developed with the mesh design, update, FEM motor, contact and simulation control optimised for ring rolling.

Unlike many ring rolling simulation solutions, “artificial” hypotheses are reduced to a minimum. The software is capable of showing the increase in local mesh density in the deformation areas. SFTC, Scientific Forming Technologies Corporation, developed an efficient and accurate simulation system specifically designed for ring rolling.

The solver uses a mix of implicit Langragiane and ALE technologies. A brick mesh (hex), used in the FEM motor, is optimised to refine the mesh in the deformation and contact areas.

What customers say about DEFORM:

DEFORM ring rolling simulation software is American and has been optimised to be reliable, quick and easy.

EXCELLENT AGREEMENT OF “SOFTWARE RESULTS” WITH “REALITY” DEFORM is the most widely used cold forming simulation software in the world
SAMPLING IMMEDIATELY POSITIVEThe simulation makes it possible to identify defects obtained during forming, to understand their causes and therefore to undertake the right corrective actions
STARTING TIMES REDUCED TO A MINIMUM The press setting was already tested in simulation. The real sampling will dispose of the machine setup card already defined.
CERTAIN RAW MATERIAL PROCUREMENTThe DEFORM deforming simulation makes it possible to assess different extruded item diameters and therefore to immediately identify the diameter for each code
REQUIRED PRESS DEFINITION DEFORM indicates the required tonnage for each workstation and therefore indicates which machine is necessary for the process. Planning of samplings and production
LONGER MOULD DURATION Tool wear known and reduced thanks to modified mould mechanics. Mould damage phenomena eliminated because expected and therefore taken care of in simulation

For the purchase, hire or a DEMO of the software or if you want to take advantage of a simulation service specially-made by our technical department, write or call us at +39 030 3365383

Ecotre Valente from Brescia proposes DEFORM to optimize costs through process simulations
Not only reductions in shiftwork and production in the lower cost ranges, energy savings can also come from a simple one software.
A popular saying goes that "necessity sharpens the wits", meaning that when you are in critical conditions it is a process of nature find new solutions to problems, and in this case to costs.
Precisely in the face of the expensive energy Ecotre Valente, it has decided to offer its customers a new weapon represented by the software DEFORM for the simulation of energy consumption in furnaces...

Validation of hot ring rolling industrial process 3D simulation

07/12/2021

DEFORM

In this work a FE model, based on Deform 3D software, was tested versus experimental results acquired from an industrial plant. The accuracy of the FE model was analyzed through a dual comparison: by geometrical and by physical aspects. A good agreement was found between experimental and numerical results for both comparisons and, as a consequence, this code could be used in order to investigate and optimize the process parameters that characterize the ring rolling process in a virtual not expensive environment. The validated model will allow the studies of more environment-friend process configurations.

Demand for the “virtual factory” rises

Ecotre Valente from Brescia distributes simulation software. Growing more than 20% annually in the last 5 years
It is a matter of time. The simulation software for casting, forging, rolling, heat treatment and machining allow to expand or compress it: ingots of tons that take days, to give just one example, can be reduced and evaluated in a few minutes; conversely, steps of a few thousandths can be analyzed in hundreds of seconds. But the time factor today is also the key to the diffusion process of these virtualization programs of the production cycle. "It's only a matter of time: even in the world of steel, the tools that allow the virtual reality of production processes will be widespread."
