            Vacuum furnace

            Release date: 2014-04-30 00:00 source: http://www.serunique.com Click:

            I. tight vacuum sealing: as we all know, the vacuum heat treatment of other parts is carried out in a closed vacuum furnace. Therefore, it is of great significance to obtain the original air leakage rate of heweicha furnace and ensure that the vacuum degree of the vacuum furnace is not carried out. Therefore, a key problem of the vacuum heat treatment furnace is to have a reliable vacuum tightness Sealing structure: in order to ensure the vacuum performance of the vacuum furnace, a basic principle must be followed in the structural design of the vacuum heat treatment furnace, that is, the furnace body should adopt airtight welding, and at the same time, the furnace body should be opened or not opened as much as possible, and the dynamic sealing structure should be used less or avoided, so as to minimize the chance of vacuum leakage. Components and accessories installed on the vacuum furnace body, such as water-cooled electrodes, etc The sealing structure must also be designed for the thermocouple export and installation.
            2. Most of the heating and heat insulation materials can only be used in the direct air state: the heating and heat insulation linings of Diankong heat treatment furnace work in the vacuum and high temperature, so the requirements of high temperature resistance, low steam pressure, good radiation effect, small thermal conductivity and low oxygen performance are put forward for this material. Therefore, tungsten, platinum and graphite are widely used in Diankong heat treatment furnace Heating and thermal insulation materials, which are easy to track under atmospheric conditions, are not suitable for conventional heat treatment furnaces.
            III. using low voltage and high current: in the stone vacuum vessel, the electrified conductor in the vacuum vessel will generate glow discharge under high voltage. In the vacuum heat treatment furnace, serious arc discharge will occur, which will burn the electric heating elements and insulation layer, causing major accidents and loss reports. Therefore, the working voltage of the electric heating elements of the vacuum heat treatment furnace generally does not exceed 80-10 At the same time, effective measures should be taken in the structural design of electric heating parts, such as avoiding the parts with tip as far as possible, and the spacing between electrodes should not be too narrow, so as to prevent the occurrence of glow discharge or arc discharge.
            IV. high degree of automation: the high degree of automation of the vacuum heat treatment furnace is due to the fact that the operation of heating and cooling of metal workpieces requires more than ten or even dozens of actions. These actions are carried out in the vacuum heat treatment furnace, which is inaccessible to the operators. At the same time, after the completion of heating and heat preservation, the quenching process of workpieces requires six actions In order to complete many work in 15 seconds, it is very easy to cause operator's tension and constitute misoperation under such rapid conditions. Therefore, only higher self work can coordinate work accurately and timely according to the procedure.
            V. water cooling device, shell, cover and electric heating element of vacuum heat treatment furnace, respectively dispose of (water-cooled electrode), middle vacuum heat insulation door and other components, all of which work in vacuum and heating state. In this extremely unfavorable condition, it is necessary to ensure that the structure of each component is not deformed or damaged, and the seal ring of Guizhou air is not overheated or burnt. Therefore, each component should be in accordance with Water cooling device shall be set in different situations to ensure the normal operation and sufficient service life of the vacuum heat treatment furnace.
