因为真空炉中的传热依靠辐射,清晰的热辐射光路很重要。在设计过程中,必须考虑接点、加热装置间隙和支撑吸热问题。大多数炉子是立式的,但这里所描述的新式炉子是卧式的。泵抽系统非常有效,设备实现了完全自动化。炉子的温度极限为1320℃,最高真空度为 Because heat transfer in a vacuum furnace relies on radiation, a clear path of heat radiation is important. In the design process, must consider the contact, heating device clearance and support endothermic problem. Most stoves are vertical, but the new stoves described here are horizontal. The pumping system is very efficient and the equipment is fully automated. The temperature limit of the furnace is 1320 ℃, the highest degree of vacuum is
