Computer Modeling of Temperature Field in Sintering Carbide Composites Using Induction and Radiation Heating

摘要

A computer model has been elaborated for the temperature field in a high-temperature furnace for sintering ceramic powder samples under induction and radiation heating conditions. For numerical solution of the set of equations describing the induction and radiation heating processes a finite-element method is used in combination with a finite-difference procedure in time, which is based on Newton-Raphson technique, and a radiosity method is used in modeling the radiation heat transfer. The temperature field in the furnace in the process of sintering has been numerically studied. The numerical results are compared to the data of temperature measurements at the infiltrator surface during the sintering of a composite blend with a silicon - carbide matrix. Based on the agreement between the calculated and experimental results, the computer model is inferred to be adequate.
