The finite element simulation and optimization method of the temperature field of vacuum heat treatment based on Fluent

Abstract

In the vacuum heat treatment process, the heat exchange process, temperature field distribution, and cooling rate field distribution inside the vacuum furnace are not easy to observe and measure directly. With the rapid development of numerical simulation technology, the production process of many actual projects can be reproduced on the computer, so that the problems in the project can be analyzed more intuitively and improvements and optimizations can be made.The simulation method generally adopted for the cooling process of vacuum heat treatment only considers the heat exchange process of the cooling gas in the heating chamber, and ignores the integrity of the heat exchange process of the cooling gas, which leads to low authenticity and reliability of the simulation results. The article proposes a cyclic cooling simulation method, and uses the cyclic cooling simulation method to simulate the cooling stage, and compares the simulation results with the experimental results to verify that the cyclic cooling simulation method has higher reliability and calculation accuracy.
