Modelling of pipe rolling process in stretch reducing mill

摘要

The paper presents a mathematical model describing the mechanical, thermal and microstructural aspects of the tube rolling in stretch reducing mill. The generalized plain strain approach and discretisation using finite elements method were applied. The equations describing the kinetics of recrystalisation and grain growth were created on the base of a number of laboratory tests and were used for modelling of microstructure evolution. In the work the results of the simulations of a selected tube rolling process were presented, as well.
