Vacuum Brazing Technology of Aluminum Alloy Plate Radiator
The so-called vacuum brazing is to clamp the materials to be brazed together with fixtures, heat them in a vacuum furnace to melt the 4004, 4104 or 4N04 aluminum alloy solder into a high temperature liquid state, and fill the welded parts (3003 alloy) under the action of capillary force. ) to ach...
Compound Gas Nitriding Treatment Process For Swing Arm Bogies
The bogie is an important structure to ensure the safe operation of rail transit vehicles, and it is also the core structure for light rail or subway trains to run smoothly at high speed. The crank arm is a key part of the bogie structure. Its functions are as follows: First, when the vehicle sta...
Compressor impeller vacuum heat treatment
The impeller, also known as the working wheel, is the most important component on the compressor rotor. The impeller rotates at high speed with the main shaft, and does work on the gas. Under the action of the impeller blades, the gas rotates at a high speed with the impeller. Under the action of...
Carbide wood knife tools vacuum brazing
This paper takes the vacuum brazing process of cutting tool carbide as the research object. By studying its process and mastering its working principle, the blanks of rotary cutting tool carbide vacuum brazing can be qualified for batch production. Vacuum brazing of carbide tools is a very import...

1.Process introduction With the rapid development of electronic technology and the integration of electronic products, the power of aerospace, military and civil electronic equipment continues to increase. and increased sharply. Studies have shown that for every 10 ℃ increase in temperature of a ...
Aluminum alloy finned radiator vacuum brazing
Plate-fin heat exchangers have the advantages of small size, light weight, and can handle more than two kinds of media. Widely used in petroleum, chemical, natural gas processing and other industries. The characteristics of plate-fin heat exchangers are: (1) The heat transfer efficiency is high. ...
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...
