Vacuum furnace, atmosphere reactor up to 3000°C

Many heat treatment processes today need to be performed under vacuum conditions. Such as vacuum metallurgy, annealing, product growth, brazing and other processes, must be combined with vacuum technology and heat treatment process. To achieve this, the sample must be placed in a closed environment. Such as gas tight tube furnace working tube, gas tight atmosphere box, or gas tight water cooling layer. This way the air is pumped out as much as possible, reducing the oxygen content, and the sample is not easily oxidized. In addition, during the heat treatment process above 1800 degrees Celsius, the oxygen content is also reduced to prevent the heating elements and insulation materials from being oxidized. It can provide different kinds of gas mixing atmosphere, such as nitrogen, oxygen, xenon and other very low content gases.
At a standard atmospheric pressure, the air contains 21% oxygen. When the furnace is being vacuumed, the oxygen pressure in the furnace is gradually reduced. Diff
