| Abstract: | To determine the temperature of heat treatment furnace is an important means to guarantee the workpiece quality, but heat exchange errors often occur in the temperature measurement. Thermodynamics and heat transfer theory are employed to analyze the causes of heat exchange error and its affecting factors. A formula for calculating heat exchange error has been advanced. By means of Oppenheim's network theory of radiation heat exchange, a network chart for radiation heat exchange of varlous substances has been drawn, and the heat exchange equation sets have been presented Meanwhile, on the basis of analysis and discusion of the way and measures to reduce the heat exchange errors, a scientific method has been developed to improve the measurement precision of the heat treatment furnace temperature. |
