Sintering principle and analysis of special ceramics
The main preparation process of special ceramics includes three steps of blank preparation, forming and sintering. After the molding process is completed, sintering can control the growth of grains and has a crucial impact on the performance of the material. So far, ceramic sintering technology ...
Development of Large High Temperature Vacuum Annealing Furnace
Buttons are refractory metals that have been widely used in cutting-edge industries. Among them, it can be used to manufacture button capacitors and launch tube electrodes in the electronics industry; it can be used as a heating element and a heat shield in a high vacuum resistance furnace; it ca...
Weld gap for vacuum brazing
The weld gap of vacuum brazing refers to the assembly gap between the surfaces of the weldment during brazing. In the process of vacuum brazing, the brazing gap affects the capillary filling process of the solder, and also affects the degree of interaction between the solder and the substrate, as...
Warm extrusion die vacuum heat treatment
Warm extrusion is a new process developed on the basis of cold extrusion. It heats the blank to an appropriate temperature for extrusion. Due to the heating of the metal, the deformation resistance of the blank is reduced, the forming is easy, the tonnage of the press can also be reduced, and the...
Microstructure evolution of vacuum tempered low carbon microalloyed steel
With the development of low-carbon microalloying and controlled rolling and controlled cooling technology, the problem of residual stress in high-strength steel has become increasingly prominent. In order to obtain high-strength steel products with excellent properties, the method of vacuum tempe...
Transformation of hardened carbon steel during vacuum tempering
Vacuum quenching is a very important process in the processing of metal materials and is widely used in modern machinery manufacturing industry. Martensite and retained austenite are the two major components of the steel after vacuum quenching. Martensite and retained austenite, which have the t...
Vacuum Heat Treatment of TV Satellite Antennas
“Live Star” is the abbreviation of broadcast and TV live satellite. Direct broadcast satellite broadcasts video, graphic and sound programs point-to-point through satellite, and directly for the majority of users to receive. The most important component of live satellite TV is the sig...
5A06 Sheet metal parts vacuum annealing
A product part is manufactured by sheet metal stamping process, and the material used is 5A06 sheet. Cracking often occurs over a period of time, and the stamping rate is low. In order to improve the forming rate of 5A06 sheet, this paper analyzes the reasons for stamping cracking, studies the ef...
Vacuum Detection Technology of Vacuum Annealing Furnace
1 Overview Vacuum annealing is an important process in the production of intermediate and finished products. Vacuum annealing has the functions of preventing oxidation, vacuum degassing, preventing surface embrittlement of titanium and refractory metals, uniform heating by vacuum heating, small t...
Vacuum brazing of the rear passage assembly of the flame tube
In a conventional combustion chamber, the flame tube mainly acts as an air distributor, which can divide the air entering the combustion chamber into several strands and distribute the air to a suitable position to organize combustion or cool the wall of the flame tube. In the next-generation com...
