Experimental study of heat transfer in hot stamping process
Source abstract
Abstract
Hot stamping and quenching of boron steel is a novel technology to produce structural automotive parts with an excellent crash performance. It offers the opportunity to produce thinner parts with complex shapes and higher mechanical properties. In order to increase the simulation expertise of the hot stamping process,, an experimental device has been designed and developed to accurately measure the thermal contact resistance (TCR) under representative process conditions. This parameter characterizes the heat transfer intensity between the tools made in Z160 steel and Usibor 1500P blank (a precoated carbon/manganese steel) at the contact interface. In this paper, we present an approach to determine experimentally the evolution of the TCR under different contact pressure (2 to 30 MPa).
