Abstract

Abstract: To improve the thermal insulation performance and temperature uniformity of vacuum sintering furnace, the thermal insulation layer parameters were optimized using the theoretical model of heat transfer. The ANSYS steady-state thermal analysis method was used to study the effects of graphite plate thickness, carbon felt thickness, and the distance between the thermal insulation layer and the heating element on the thermal insulation performance and temperature field of the vacuum furnace. The results show that, 150 mm-thick carbon felt can largely improve the thermal insulation performance and temperature uniformity, but such improvement is little with further increasing the felt thickness. When the distance between the thermal insulation layer and the heating element is 80 mm, the temperature on the inner side of the thermal insulation layer reaches as high as 1 008.5 ℃. Moreover, compared with the case of original 100 mm-distance, the number of uniform temperature points increases by 10.4%. The thickness of the graphite plate has little and negligible effect on the temperature field.

Key words: vacuum sintering furnace, ANSYS steady-state thermal analysis, thermal insulation performance, temperature uniformity
