Vacuum Furnaces Leaks and Detection Techniques
For the leak detection of the vacuum heat treatment furnace, it includes two parts: the furnace body and the vacuum system. After the furnace body and the vacuum system are assembled, no matter how reliable the seal is, there will always be air leakage in general. The gas leakage rate of the vacu...
Process optimization of alumina ceramic sintering technology
Vacuum sintering technology of alumina ceramics. Pure alumina ceramics have a very high melting point, and the sintering temperature can be as high as 1800°C. High sintering temperature not only consumes a lot of energy, but also has many defects in the structure of the sintered ceramic parts, wh...
Atmospheric Pressure and Vacuum Sintering of High Purity Dense MgO Ceramics
Features of Magnesium Oxide: Magnesia ceramics have a large coefficient of thermal expansion, a melting point of 2800°C, and good insulation. High-purity magnesia ceramics have strong corrosion resistance to metals and alkaline solutions, and are used as crucibles for melting high-purity iron an...
Vacuum Brazing solutions for Cutting and Grinding Tools
Cutting and grinding tools refer to the knives used by mining machinery to cut coal and rock. Working under complex and changeable working conditions is the part with the greatest loss in the construction of rotary drilling rigs. The failure forms of cutting and grinding tools mainly include allo...
Alumina ceramic densely sintered
With the improvement of the production level, alumina ceramics have also been favored in the optical field in recent years. When the alumina ceramics are fully densified, the light transmittance is greatly improved and it is translucent. It can be used to replace single crystal sapphire and make ...
Vacuum Hardening Strengthening Process for Low Carbon Steel
Some parts in the textile machine were originally made of malleable cast iron, which had low mechanical properties and often broke during work. 20 steel vacuum hardening was used to replace the original malleable cast iron material. The actual operation proved that the service life was increased ...
The characteristics and working principle of vacuum heat treatment furnaces
Vacuum heat treatment is a kind of heat treatment process. As long as it involves the field of mechanical manufacturing, heat treatment is a widely used and very important basic process. Metal materials after vacuum heat treatment can give full play to their performance potential, which is very i...
Maintenance of Vacuum Carburizing Furnaces
The application of vacuum carburizing treatment technology has spread to all walks of life, and it is one of the indispensable heat treatment methods in industrial development. The surface of the workpiece after vacuum carburizing treatment is smooth, with high mechanical properties and long serv...
Applied Crack Repair Technology of Vacuum Brazing
Speaking of the perception of soldering, the scene of connecting electronic components with electric soldering iron and tin wire will appear in everyone’s mind, which is the most common welding method in soldering connection. Brazing is divided into hard brazing and soft soldering according...
Vacuum carburizing process of transmission gear
The vacuum carburizing process that carries out carburizing treatment under reduced pressure has many advantages such as no grain boundary oxidation, no abnormal carburized layer on the surface of the workpiece, shortened heat treatment time, less exhaust gas, and energy saving. It is the most su...
