Finite elements method (FEM) simulation based prediction of deformation and temperature at rolling of tubes on a pilgrim mill

3D - FEM simulation was used as an efficient tool for description of stress-deformation thermal field at rolling of tubes on a pilgrim mill.The monitored objectives comprised also behaviour of working tools at this rolling.This paper assumes rolling of already pierced thick-walled blank, which passes through the pilgrim stand at simultaneous reduction Elbow Support of thickness of inside toe straps and outside diameters at the expense of elongation of initial length.Main attention is focused on the mentioned parameters with respect to various conditions of rolling, such as different heat transfer, different friction or different distance of insertion of the rolled product into the gauge.

The input data used at simulation were derived from real conditions of tubemaking.
