Difference between vacuum hot pressing furnace and vacuum furnace

Vacuum hot pressing sintering furnace is usually used for rapid and high-grade cermet, composite ceramics, nano phase, gradient function, mesoporous nano thermoelectricity, alloy glass non-equilibrium state and biomaterial sintering.

Vacuum furnaces are often used for metal materials.
In addition, the layout of vacuum hot pressing furnace is different from that of vacuum furnace.
The vacuum hot pressing sintering furnace consists of a sintering furnace and a vacuum pump. The sintering furnace includes a furnace body and a heating chamber installed on the furnace body. The sintering furnace is equipped with an lead-in electrode, which is characterized in that the upper and lower parts of the furnace main body are connected with the upper beam and the lower beam of the hydraulic press, the upper beam of the hydraulic press and the lower beam of the separation hydraulic press are connected into a whole by four pillars; the upper magnetic head is connected with the head graphite of the upper water-cooled head and the upper water-cooled head, which is composed of the head graphite of the water-cooled head and the head graphite of the lower pressure. The upper pressure head and the lower pressure head are separated from the through holes of the upper side and the lower end pressure head of the upper furnace body and the heating chamber, and are inserted into the furnace body. The graphite of the upper and lower indenters is separated and inserted into the heating chamber, and the upper and lower indenters can move up and down.

Vacuum furnace usually consists of furnace, electric heating device, sealed furnace shell, vacuum system, power system and temperature control system. The sealed furnace shell is made of carbon steel or stainless steel by welding, and the detachable parts are sealed with the joint surface of vacuum sealing material. In order to prevent deformation from deteriorating from the shell and the sealing material after heating, the shell is usually cooled and cooled by water or air. The furnace is located in the sealed furnace shell. According to the functions of the furnace, different types of heating elements are installed in the furnace, such as resistance, inductance coil, electrode, electron gun, etc. the vacuum furnace for smelting metal is equipped with a crucible, and some active dumping devices and manipulator are used for loading and unloading. The vacuum system consists of vacuum pump, vacuum valve and vacuum gauge.
