Abstract

The invention discloses a vacuum furnace. The vacuum furnace comprises an outer furnace shell, an interlayer shell, an inner furnace shell, a furnace cover, a support, a heating crucible, a heater, a vacuum pipeline, an inflation pipeline and a cooling pipeline. The inner furnace shell is sleeved with the interlayer shell. The outer furnace shell is arranged outside the interlayer shell. The furnace cover is arranged on the inner furnace cover. One end of the furnace cover is connected with the outer furnace shell. The vacuum pipeline passes through the outer furnace shell and the interlayer shell and is arranged at the lower end of the inner furnace shell. The inflation pipeline is arranged on the side of the inner furnace shell. The cooling pipeline is arranged on the outer furnace shell. A support is further arranged in the inner surface shell. The heating crucible which is coaxial with the inner surface shell is arranged at the center of the support. The heater is arranged around the heating cubicle. In this way, the vacuum furnace has the advantages of being high in reliability, good in vacuum effect, compact in structure, low in shell temperature, high in adaptability, stable in operation, high in heat isolation ability and the like.

Description

technical field [0001] The invention relates to the field of vacuum equipment, in particular to a vacuum furnace. Background technique [0002] The vacuum furnace uses the vacuum system in the specific space of the furnace cavity to discharge part of the material in the furnace cavity, so that the pressure in the furnace cavity is less than a standard atmospheric pressure, and the space in the furnace cavity achieves a vacuum state. This is a vacuum furnace. Due to the internal vacuum, the heating of this equipment has the advantages of no oxidation, no pollution, temperature control, precise energy consumption, etc., but due to the high internal temperature, there is a large heat radiation, which makes the furnace wall heated, and a large amount of heat is taken away, and the energy saving effect is relatively low. Difference. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a vacuum furnace, which prevents hea...
