Cherny O. Design of thermal and termostressed being of bars

Object - thermal and termostressed being of metallic bars under various conditions (including nonlinear) heat exchange; a purpose is the receipt of close analytical decisions of dvumernih tasks of heat conductivity, that heating of bars is designed in the most widespread technical terms of heat exchange, taking into account physical-mechanical performances and nonlinear; methods are the method of equivalent sources (task of heat conductivity), the Menage method (task of termostressed); novelty - in relation to the design of processes of heat treatment of prismatic bars the method of equivalent sources is first used, got in an obvious kind for different terms of heat exchange analytical decisions, are comfortable for the high-quality analysis of affecting the process of factors, on the basis of them the functions of temperature tensions were got and the proper modes of heat treatment of bars are offered; new approach to the decision of nonlinear tasks of heat conductivity, that allowed to link the dynamics of change of the temperature field of bar with thermal tensions arising up in him; results - the got functions of temperatures and built on their basis of decision of tasks of termoеlasticity allow to conduct the high-quality analysis of thermal processes and various calculation-experimental researches of work of stoves; introduction of the developed methods in practice of metallurgical production in the stove of figure 150 RUP "BMZ" allowed to set the rational temperature-thermal modes, that gave a by shares economic effect to a 15 000 dollar; industry - prom power system.
