Název v původním jazyce

Influence of undercooled surface of CCSP on core propagation of plastic deformation

Popis výsledku v původním jazyce

The presented paper describes computer simulation of the square billet rolling from the input round semi-product. The influence of undercooled surface layers of continuously cast semi-product (CCSP) on the propagation of the plastic deformation to the core of the rolled product was investigated via PC simulation. The simulation was performed with 2D FormFEM 1.5 simulation program of forming processes. The employed method of design can be called " 2,5D ", i.e. simulation of metal flow in the plane of rolling only, with cross section reduction according to the actual elongation coefficient.Simulation results (for all 17 passes and 4 degrees of undercooling of surface) are as follows: stress intensity field, dependence of temperature on a distance from the core to the surface for x and y axis, strain intensity dependence on a distance from the core to the surface for x and y axis. Our presumption, that alternative cross section behaviour of deformation resistance caused by undercooled sur
