SGM VF2000 degree vacuum hot pressing furnace/vacuum hot pressing experimental furnace

SGM HPF2000 degree vacuum hot press furnace is a small experimental vacuum experimental furnace produced by Luoyang Sigma high-temperature electric furnace, also known as an air atmosphere furnace. The vacuum hot press furnace can be heated with graphite, molybdenum wire, or tungsten wire. The 2000 degree vacuum hot press furnace can use graphite heating and tungsten wire heating.

The loading pressure can be selected from 30T, 50T, 100T, 200T, 400T, 500T, 800T, 1000T, and 2000T;

The furnace temperature can be selected from 1400 ℃, 1500 ℃, 2000 ℃, 2200 ℃, 2300 ℃, and 2500 ℃;

The pressure chamber is equipped with a load-bearing frame press structure, with single or multiple hydraulic cylinders at the upper and lower parts, positioned vertically and horizontally, and subjected to bi-directional pressure;

Hydraulic system:

The hydraulic system consists of an electric hydraulic station, hydraulic cylinders, and fixed frames. The hydraulic cylinder is installed in the middle of the furnace base. Hydraulic oil is used through an electric hydraulic system to raise and lower the oil cylinder, which can achieve the functions of pressure regulation and holding. According to the user's process requirements, the function of automatic pressure regulation can be achieved by setting an intelligent digital display program instrument; Both pressure and displacement are displayed using digital instruments.

Application of small vacuum hot pressing furnace

Suitable for sintering metal powders, inorganic non-metallic materials, etc. under vacuum high-temperature hot pressing, or hot pressing sintering under protective atmosphere.

Therefore, the material can be densified, deformation can be prevented, and the coarse grain of nano powder can be restrained.

Features: This device has high integration, small footprint, and is mainly used for research in research institutes and laboratories.

Characteristics of commonly used heating elements in vacuum resistance furnaces:

Molybdenum: Generally used in a 1600 ℃ vacuum sintering furnace, its volatilization accelerates at 1800 ℃ and weakens due to pressure factors in the protective atmosphere of hydrogen gas. It can be used up to 2000 ℃;

Tungsten: generally used in vacuum sintering furnaces at 2300 ℃, with accelerated volatilization starting at 2400 ℃ and reduced volatilization due to pressure factors in the protective atmosphere of hydrogen gas. It can be used at 2500 ℃;

Tantalum: Generally used in 2200 ℃ vacuum sintering furnaces. Unlike tungsten and molybdenum, tantalum cannot work in atmospheres containing hydrogen and nitrogen. Its advantages are better mechanical processing performance and welding performance than tungsten and molybdenum;

Graphite: Generally used in a 2200 ℃ vacuum sintering furnace, it evaporates significantly faster at 2300 ℃, and evaporates less in a protective atmosphere (inert gas) due to pressure factors. It can be used at 2400 ℃;
