TEMPERATURE FIELD OF A WELD SIMULATION FOR TECHNOLOGY OF LOCAL HEAT TREATMENT DEVELOPMENT

摘要

Using the method of elementary thermal balance-sheets, a model of two-dimensional temperature wail of a hollow cylinder under local heating of annular zone by electric heaters of resistance. The dependence of thermophysical properties of the wall material on temperature, heat emission coefficients changeability by convection and radiation on the external surface, and also heat transfer by radiation in the vessel are taken into account.
