“…Metal temperature is one of the most important processing factors of pressure metal treatment (PMT) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], which determines energy-power conditions and product quality. Thermal cycle of rolling has a great impact on mechanical properties, deformation resistance, structure and quality of rolled products.…”

The paper reviews and develops the mathematical model of plastic flow during the hot-forming processes. A flat non-stationary temperature problem for a cross-section of a long solid (rolled product) of arbitrary shape with different heat transfer conditions along the perimeter of the cross-section was considered. Equations for calculation of the thermal conductivity coefficient and heat capacity of tungsten billets were obtained in the temperature range of 700 - 1500°C, based on the literature data. Analytical dependences in form of regression equations were obtained, allowing for computer calculations of physical specifications of 11x11 mm VA grade tungsten billets in form of temperature functions with accuracy sufficient for practical calculations.
