Aluminum radiators vacuum brazing oven
New Technology of Aluminum Vacuum Brazing Radiator 1.Overview of aluminum vacuum brazing radiator As a key part of the car cooling system, the radiator plays an important role in the whole car. It forms the cooling system with the cooling fan, rubber tube, engine water jacket, thermostat, cooling...
Oil Cooler Vacuum Brazing Process
The oil cooler is mainly used to cool the engine lubricating oil to stabilize the lubrication system, improve the power and economy of the automobile engine, and is an important part of the automobile heat exchange system to ensure the safe operation of the engine and its service life. In recent...
Vacuum Hardening of Tool Steel
There are two types of classification of tool steel in engineering, one can be divided into: carbon tool steel and alloy tool steel according to the composition; the other can be divided into: cutting tool steel, die steel and measuring tool steel according to the use. In addition, it can also be...
Vacuum Hardening of Alloy Steel
The so-called vacuum hardening is to heat the steel to 30-50°C above Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel) under vacuum conditions, and put it into various cooling media after heat preservation to obtain Martensitic steel. body tissue. The purpose of vacuum hardening is to trans...
Aerospace Vacuum Heat Treatment
The aviation industry is a high-tech industry, which adopts a large number of cutting-edge science and technology, selects various new materials with high specific strength, develops near-zero margin forming technology, precision and ultra-precision processing technology, and so on. In order to e...
Vacuum hardening of metal parts
Advantages and disadvantages of vacuum hardening of metal parts The surface of the workpiece after vacuum hardening of metal parts is bright, without carburization and decarburization. It can improve the service life of tools and dies that are subjected to friction and contact stress; after vacuu...
Vacuum Furnace For Powder Metallurgy
The structural characteristics of the vacuum furnace mainly include: (1) Powder metallurgy vacuum furnaces require strict vacuum sealing. Vacuum sintering or vacuum heat treatment of metal products is carried out in a closed vacuum furnace. Therefore, obtaining and maintaining the original air le...
Precautions For Daily Use Of Vacuum Furnaces
After vacuum furnaces are repaired, the furnace must be baked and vacuum leak detection must be carried out on the vacuum furnace. Before the vacuum furnace is baked, a 1000V shaker can be used to test the insulation of the vacuum furnace, which is normally not less than 2MΩ. Vacuum furnace dryin...
Defects and Improvements of Vacuum Furnaces
Vacuum heat treatment technology is widely used in aerospace, electronics, precision machinery. In the production of molds, there are incomparable outstanding advantages of ordinary heat treatment, because vacuum heat treatment has the advantages of non-oxidation, non-decarburization and bright s...
Improvement of Sealing Structure of Vacuum Furnaces
The vacuum furnace used for cemented carbide vacuum sintering has a design temperature of 1600°C, a volume of 50L, and a power of 50kW. The heating element is assembled with graphite rods, its working voltage is low (phase voltage<20V), and its working current is large (phase current>1000A)...
