Design of the installation for production of melt materials and method for determination of its thermal conductivity

K.B. Isayev, V.V. Remeslo

The installation design for production of melt of materials in conditions of one sided heating is submitted. It is intended for determination of a temperature fields in melt and substrate. On the basis of these fields the thermal conductivity of melt is determined. The method for determination of melt materials thermal conductivity is based on a fourth sort boundary condition between a substrate and melt, decisions of coefficient and boundary inverse heat conduction problems. The results of experimental determination of a temperature field in a graphite substrate and temperature of a surface of tin melt, and also results of determination of contact temperature of a melt-substrate are submitted. The results of determination of thermal conductivity of tin melt are given. The satisfactory consent with the literary data is received.

Key words: a tablet, melt, thermal conductivity, thermocouple, temperature field, inverse heat conduction problem (IHCP).
