摘要/Abstract

摘要： 金属炉胆的真空炉主要用于处理一些对真空气氛要求较高的金属产品,炉胆的隔热屏制造成本较高并且不易改动。通过对WZDGQ-40型真空炉的金属隔热屏保温效果进行仿真研究,得到每层隔热屏的温度场情况。结果表明,调整中间两发热带的距离为200 mm时,炉胆外层温度降低80 ℃。合理的发热带宽度和发热带间距能够较好提高炉胆的保温效果,为今后该类型装备制造提供一定的参考价值。

Abstract: Vacuum furnace with metal furnace bladder is mainly used to process some metal products which require a high vacuum atmosphere. The heat shield of the furnace is relatively expensive to manufacture and difficult to modify. Through simulation on the thermal insulation effect of the metal heat shield of the WZDGQ-40 vacuum furnace, the temperature field of each heat shield was obtained. The results show that when the distance of the two middle heating belts is adjusted to 200 mm, the temperature of the outer layer of the furnace is reduced by 80 ℃, which means that reasonable heating belt width and heating belt spacing can improve the thermal insulation effect of the furnace, and that the simulation can provide a certain reference value for the manufacture of this type of equipment in the future.

Key words: vacuum furnace, furnace bladder, numerical simulation, thermal insulation effect, heating belt
