Heat Treatment of DZ4 Alloy in High Pressure Gas Quenching Vacuum Furnace
The vacuum high pressure gas quenching process has been used for more than ten years since the 1980s. Especially in the aviation I plant, equipment has been purchased, but due to the lag in process research, the equipment has been put on hold for a long time. The vacuum high pressure gas quenchin...
Vacuum Brazing Technology of Stainless Steel Radiator Core
The stainless steel high-pressure radiator of the fuel cooling lubricating oil system in the aircraft engine is an indispensable part of the engine. The radiator has a tubular structure. In order to meet the heat exchange requirements, hundreds of 0.2mm thin-walled thin tubes are used, and they a...
Vacuum brazing furnace
Vacuum brazing is used to construct high temperature strength material system, which has the advantages of no pollution, energy saving, improving production efficiency and improving working environment, so it has been widely used in industrial production. At present, it is developing towards larg...

Technology is introduced Vacuum heat treatment is a comprehensive technology combining vacuum technology and heat treatment. It refers to the whole and part of heat treatment process is carried out in vacuum. Vacuum in China is divided into low, medium, high and ultra-high vacuum.Vacuum heat trea...
Vacuum sintering furnace
Vacuum sintering furnace refers to the furnace of protective sintering of heated items in the vacuum environment, its heating methods are more, such as resistance heating, induction heating, microwave heating and so on. Vacuum sintering furnace is the use of induction heating to be heated items f...
Vacuum Heat Treatment of Hand Hacksaw Blades
With the development of manufacturing technology, the high-carbon steel hand-used hacksaw blades that have been used in China for many years will gradually be replaced by high-speed hacksaw blades. The high-speed steel hand saw blade has undergone three stages of development. The first generation...
Application Of Partial Pressure In Vacuum Heat Treatment
Heat treatment under vacuum conditions is called vacuum heat treatment. Vacuum heat treatment is an ideal bright heat treatment technology without oxidation and decarburization. However, in the process of vacuum heat treatment, the evaporation of metal elements, the depletion of alloy elements on...
Steel for Cold Swing Rolling Die and Its Vacuum Heat Treatment
The cold swing milling process is widely used in the metal plastic precision forming of small and medium-sized rotary parts. Such as automobile gear cams, etc., the mechanical characteristic of the cold swing milling process is that the machining hair is damaged locally and continuously. Periodic...
Vacuum Brazing of Ceramics and Metals
The general process of ceramic and metal brazing can be divided into seven processes: surface cleaning, paste coating, ceramic surface metallization, nickel plating, brazing and post-weld inspection. Surface cleaning is to remove oil, sweat and oxide film on the surface of the base material. Meta...
Vacuum Heat Treatment of Hot Extrusion Dies
In order to prevent the surface oxidation, decarburization and carbon increase of the mold during heat treatment, salt bath or box furnace protection heating was mainly used in the past, and controllable atmosphere heating has also been used in recent years. When heated at high temperature, it is...
