Description
“KoPROFILE” is the first analytical simulation program for profiled ring rolling with calculations times of less than 1 minute for a whole process.
The user can now make multiple calculations with variations of process parameters. “KoPROFILE” is the first real optimization tool for ring rolled products.
It reduces significantly the development costs of a product (tool, material and energy)
This is especially important for metals like Titanium- or Ni-base alloys with their tendency to overheat locally during rolling and destroy the microstructure.
“KoPROFILE” executes:
- the design for all shapes of product, main roll and mandrel
- an automatic generated proposal for a suitable blank shape
- the short calculation time enables to optimize many process
parameters. Good or bad consequences of changes can be seen
directly.
- control, analyzation and optimization of
- the material flow during rolling (filling/emptying => geometric
quality)
- the local stress- and the local forming degree distribution
(porosity size, surface cracks, microstructure homogeneity
=> sufficient material properties)
- the local temperature distribution during rolling (keeping the
permissible temperature limits => prevention of process-related
local material damages)
- Detailed rolling parameters for practical implementation into a
machine control are generated.
Benefits using "KoPROFILE":
- Conservatively estimated approx. 50% reduction of development costs
of a product
- Gaining an "objective" inhouse Know-How, which is no longer
"subjectively“ dependent to employees
- Immediate achievement of competitiveness in the market, even for
producers who not yet made profiled rings
- Continuous improvement of products which are already in production
- Saver feasibility studies of a product
- Fast cost calculations for quotations
The presentation demonstrates these features of “KoPROFILE”. The material flow “filling/underfilling” of the profile groves, the local stress distributions together with the local forming degrees, and on this basis the controlled local temperature distribution is shown.
