Ingot bottom vacuum heat treatment
The spindle is one of the main components of twisting and winding on the spinning machine, and it is an assembly with a slender rotary shaft supported by two points as the main body. There are spindles on the roving frame, spinning frame and twisting frame. The roving spindle is a round steel rod...
CVD Diamond Tool Brazing
With the development trend of lightweight and high-strength workpiece materials, more stringent requirements are put forward for the tools used in material cutting. Diamond tools have the advantages of extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, hi...
Waveguide Slot Antennas Vacuum Brazing
Waveguide slot antennas have been greatly developed since the middle of last century, and are widely used in various fields such as ground, shipboard, airborne, and navigation. Because the slot array antenna is easy to control the amplitude distribution in the antenna aperture plane, the apertur...
304 stainless steel sound-absorbing honeycomb vacuum brazing
The sound-absorbing honeycomb structure is composed of a perforated panel, a honeycomb core and a non-porous panel, which are connected by vacuum brazing or bonding. The sound-absorbing principle of the sound-absorbing honeycomb is mainly to use the sound wave to enter the Helmholtz resonant cavi...
Carbide Vacuum Brazing Process
Common process methods of vacuum brazing The main technological parameters of the vacuum brazing process are brazing temperature and holding time. The brazing temperature is usually selected to be 25-60°C higher than the liquidus temperature of the solder to ensure that the solder can fill the ga...
Vacuum brazing process of Ag-Cu eutectic solder
Copper and copper alloys usually have excellent electrical conductivity, thermal conductivity and excellent corrosion resistance in some media, and some copper alloys also have high strength, so they are used in electrical, chemical, oxygen, brewing, food, Industrial sectors such as power and tra...
Vacuum annealing process of steel ring
Textile equipment traveler is an easy-wearing part used in conjunction with steel rings on textile machinery. The main failure mode of steel ring and traveler is friction and wear, and the wear of machine parts mainly starts from the surface. Therefore, when the structural form and material are d...
Causes and Control of Deformation in Metal Vacuum Heat Treatment
As we all know, the performance of the workpiece after vacuum heat treatment will be better and more in line with the performance requirements of mechanical parts. However, in the process of vacuum thermal processing, some problems will occur in metal materials, such as deformation. The appearanc...
Separate heat pipe radiator vacuum brazing
The separated heat pipe radiator is a new type of heat exchange equipment evolved from the heat pipe radiator, which can be installed on the flue, gas pipe and combustion air pipe of the hot blast stove respectively. Advantages of separate heat pipe radiators The separated heat pipe radiator cons...
Tool and mold vacuum heat treatment process
Vacuum heat treatment has the advantages of high quality, low energy consumption, no pollution (or less pollution), etc. It can effectively prevent tool and mold defects, improve surface roughness, and reduce friction factor. The vacuum heating is carried out in the form of radiation, the heating...
