Aluminum plate-fin type heat exchanger and vacuum brazing
Aluminum plate-fin type heat exchanger (hereinafter referred to as heat exchanger) is a pressure vessel, and must meet the corresponding pressure requirements during its application. Due to its structural characteristics, its welding process can only be achieved through vacuum brazing. Vacuum bra...
Selecting the Right Vacuum Oil Quenching Furnace for the Job
Considerations for selecting a vacuum oil quenching furnace The variety of vacuum oil quenching furnaces has increased significantly in recent years. There are now many options to choose from, and the user must carefully analyze the equipment that best suits their production needs. The following ...
What Are The Benefits Of Oil Quenching?
Hardening of steel is one of the main vacuum heat treatment processes. In this process, which was originally carried out with aqueous solutions, the quenching medium affects the final properties of the steel and can be controlled to optimize the hardness, microstructure and deformation of the tre...
Vacuum Brazed Liquid Cold Plate
Advantages of aluminum alloy for liquid cooling plate Aluminum alloy is widely used in aerospace, construction, electrical appliances, automobiles, ships and other departments due to its light weight, good corrosion resistance, excellent thermal conductivity and electrical conductivity, and its u...
Vacuum brazing process of liquid cooling plate
There are two main materials for liquid cooling plates: copper and aluminum. Copper is expensive and weighs much more than aluminum of the same volume. Therefore, in many places, aluminum is used wherever it can be used, and copper is chosen as a last resort. Aluminum alloy liquid cooling plates ...
Effect of vacuum carburizing and quenching process on gear distortion
Gears are important parts in transmission machinery and are required to have comprehensive properties such as wear resistance, resistance to surface contact fatigue and resistance to bending fatigue. At present, vacuum carburizing is the mainstream process method in the manufacture of high-param...
Vacuum Heat Treating Cold Work Tooling
Cr12 mold steel is a high-carbon, high-chromium cold work mold steel with good hardenability and wear resistance. However, due to its high carbon content, it is easy to form uneven eutectic carbides, so its impact toughness is poor. Easily brittle. After the vacuum quenching process, Cr12 mold st...
Heat treatment of tool steels in vacuum furnaces
Tool steels for molds (SKS, SKD, SKH) are mostly carbide tool steels. Mold performance not only depends on the internal structure of the steel (carbide shape, size, distribution state), but also the structural changes caused by vacuum heat treatment, especially vacuum quenching and vacuum temperi...
Lean vacuum Heat Treatment for Distortion Control
In the production process of automobile transmission gears, vacuum carburizing and quenching process is an important heat treatment process in gear production. After vacuum carburizing and quenching, the strength, wear resistance and service life of the gears have been greatly improved. The vacuu...
Experimental study on vacuum carburizing process of high-quality gear steel
Gear carburizing is usually around 930°C, and parameters such as carburizing time and carbon potential are generally selected based on layer depth requirements. According to the theoretical values of carburizing time under different layer depth requirements, it can be seen that increasing the c...
