Department of Metal Forming, School of Materials and Metallurgy,Northeastern University, Shenyang110006, P. R. China

Abstract:CASTEX(Cast Extruding) is a relatively new process in the metal working and a further improvement of the CONFORM(Continuous Extrusion Forming) process with feedstock changing into molten metal instead of granular feedstock or rod. A deformation zone division has been made and a driving power formula of wheel groove has been established by applying the Upper-Bound Theorem to the CASTEX process. It is shown by experiment and calculation that the calculated results are in agreement with the experimental ones.

 

Key words: casting extrusion continuous extrusion upper-bound theorem
