Embodiment Construction

[0015] The present invention will be further described below in conjunction with the drawings.

[0016] Such as Figure 1-2 As shown, an externally heated vacuum heat treatment tank includes a tank body 1, a bottom of the tank body is sealed, and a top opening. The opening on the top of the tank body is provided with an air extraction assembly 2 hermetically connected with the tank body. The outer periphery of the middle part is provided with a heat-resistant chuck 3 for placing at the door of the resistance furnace, and a water-cooled box 4 is provided above the heat-resistant chuck. The water-cooled box is attached to the outer wall of the tank, and the lower end of the water-cooled box is provided There is a water inlet 41 and a water outlet 42 on the upper end. It is characterized in that a barrier door 5 is provided inside the tank body and located at the upper end of the heat-resistant chuck, above the barrier door and located on the tank body There is a manipulator 6 insi...

Abstract

The invention discloses an external heating type vacuum heat treatment tank in the field of heat treatment devices. The external heat type vacuum heat treatment tank comprises a tank body, wherein thebottom of the tank body is sealed, and the top of the tank body is open; an air suction assembly which is in sealed connection to the tank body is arranged at the opening in the top of the tank body,the air suction assembly is provided with an air suction pipe communicating with the interior of the tank body, and the periphery of the middle part of the tank body is provided with a heat-resistantchuck used for being placed at a gate of a resistance furnace. The external heating type vacuum heat treatment tank has the advantages of being simple in structure, easy to manufacture, and simple and convenient to operate and maintain; an electric heating element can be heated outside a vacuum tank, the phenomenon of vacuum discharge is avoided, and other electrical problems such as short circuit and carbon deposit are avoided; a mold is sealed in a furnace tank, and does not generate chemical reactions with an electric heating element, a furnace lining and the like; and the production is safe and reliable, the volume of the vacuum tank is small, the number of accessories in the tank is small, the vacuum sealing is easy, the gas extraction amount is small, and the required vacuum degreeis easy to achieve.

Description

Technical field [0001] The invention relates to the field of heat treatment, in particular to an externally heated vacuum heat treatment tank and a heat treatment method. Background technique [0002] Modern vacuum heat treatment technology is an advanced technology for material modification, that is, normalizing, annealing, heat treatment, tempering and other heat treatment of the mold to be added in a vacuum environment. The vacuum heat treatment technology has no oxidation, no decarburization, degreasing, and degassing. , Energy-saving, clean, pollution-free, pollution-free, and high degree of automation. After vacuum heat treatment, the material surface weight is good, the deformation is small, the overall performance is excellent, the service life is long, and the accuracy is high. Therefore, vacuum heat treatment technology has become a hot spot for international development. However, the structure of the traditional internally heated vacuum heat processor is more complicat...
