  Key points of vacuum carbonization furnace cavity processing

Key points of vacuum carbonization furnace cavity processing

In vacuum carbonization furnace, in order to reduce the surface area of cavity inner wall, sandblasting or electropolishing is usually used to obtain a smooth surface. The cavity of ultra-high vacuum system in vacuum furnace is treated by electropolishing.

In principle, it is necessary to select internal welding for argon arc welding of ultra-high vacuum chamber, that is, the welding surface is on the side of vacuum, so as to avoid dead corner and false leakage. Two layer welding and two layer sealing are not allowed in vacuum chamber of vacuum carbonization furnace.

A lot of gas molecules or other organics are adsorbed on the surface of the inner wall of the vacuum chamber, which becomes the exhaust gas source affecting the vacuum degree. In order to achieve ultra-high vacuum, it is necessary to bake the chamber at 150 ~ 250 ℃ in order to release the gas inside and outside the material as soon as possible. The baking methods include wrapping the heating belt around the outer wall of the chamber, fixing the armored heating wire on the outer wall of the chamber or directly placing the chamber in the baking tent. The more economical and simple baking method is to use the heating belt. The outside of the heating belt is wrapped with aluminum foil to avoid heat loss and make the cavity heated evenly.

Stainless steel is the main structural material of ultra-high vacuum system. Among them, 300 series stainless steel (Table 1) is a low carbon steel containing 10% ~ 20% Cr, which has excellent corrosion resistance, low outgassing rate, non-magnetic, good weldability, low conductivity and thermal conductivity, and can work at - 270 ~ 900 ℃. It is widely used in high vacuum and ultra-high vacuum systems.

  Common leakage detection of high temperature vacuum brazing furnace
Posted by: yanyan - 02-25-2021, 08:27 AM - Forum: Dedicated Server - Replies (7)

Common leakage detection of high temperature vacuum brazing furnace

Use vacuum mud to seal the suspicious leakage point. At this time, pay attention to observe the change of vacuum degree. If the vacuum degree rises quickly after sticking vacuum mud and drops obviously after removing it, it means that it is a leakage point. However, this method is rarely used in practical detection.

In high temperature vacuum brazing furnace, the leak detection method is an indispensable skill in the field of vacuum leak detection. It is widely used in vacuum leak detection because of its high leak detection efficiency, simple operation, flexible instrument response, high precision, and not easy to be interfered by other gases. Helium mass spectrometer leak detector is an air tightness detection instrument based on the principle of mass spectrometry

The mass spectrometer chamber is composed of analyzer, ion source, analyzer, cold cathode ionization gauge and collector. The electrons emitted by the filament in the mass spectrometer chamber vibrate back and forth in the chamber and collide with the gas in the chamber and the helium entering the chamber through the leak hole to form positive ions. These helium ions enter the magnetic field under the effect of accelerating electric field, Under the effect of Lorentz force, different ions can reach the receiving electrode through magnetic field and receiving slit by changing the accelerating voltage. Among them, helium injection method and helium absorption method are the two most commonly used methods for helium mass spectrometry leak detection

  HISTORY OF DARK WEB SITES

[Image: cropped-1314-9.png]
The dark web, like its presence, has a very interesting past. It began almost with a clear net and went side by side. It was the Irish programming specialist, Ion Clarke, who began the Free Net idea. For global computers, this has become a peer-to-peer scheme. The key attraction of the free net was the centralisation of data via dark web sites. As anonymity was the buzz word back then as well, this became a big success. Users have benefited from expressing their concerns in an anonymous format through remaining anonymous. This led to TOR, the acclaimed dark web browser and Invisible Internet Project, being created.
