Three sworn brothers of the vacuum heat treatment furnace

"Three sworn brothers of the vacuum heat treatment furnace
The classification of the vacuum heat treatment furnace many confusion, today for you in detail about the vacuum heat treatment furnace, the three major points to according to use can be divided into the vacuum quenching furnace, vacuum tempering furnace, vacuum annealing furnace "three brothers".
1, vacuum quenching furnace; Vacuum quenching furnace can be divided into the vacuum oil quenching furnace and vacuum gas quenching furnace.
Vacuum oil quenching furnace is suitable for steel, spring steel, stainless steel, bearing steel, high temperature alloy steel such as vacuum heat treatment. Its main characteristic is wide applicable data size, strong hardenability, low capital and quenching oil can be repeated use. Deficiencies; The deformation relative to a few bigger, workpiece follow-up needs cleaning. Vacuum oil quenching furnace and three from the layout can be divided into double chamber furnace chamber furnace, etc.
Vacuum high-pressure gas quenching furnace is suitable for high speed steel, stainless steel, steel and so on some vacuum heat treatment of hardenability better data, characterized by small parts deformation, don't need cleaning after heat-treatment. Deficiencies have quenching gases Can't take back, capital is higher. Vacuum high-pressure gas quenching furnace from the layout can be divided into horizontal and vertical two kinds. Horizontal can be divided into single room, double room and 3 rooms, etc. The application of the vertical ring shape, tubular and long rod parts heat treatment. High vacuum pneumatic quenching furnace quenching pressure is usually 2 b a r ~ 10 b r a. According to the needs of users can select parts suitable for pressure of furnace type.
2, vacuum tempering furnace, vacuum tempering furnace can be divided into the single room, double room, and vertical usually choose nickel chromium with highest heating temperature is 800 ℃. Vacuum tempering furnace usually applicable requirements after tempering parts appearance of light, no oxidation color.
3, vacuum annealing furnace, vacuum annealing furnace can be divided into single rooms, double rooms and vertical. Vacuum annealing furnace can be selected in high temperature, low temperature, according to the parts data (in the high temperature of 800 ℃ ~ 1350 ℃, low temperature 800 ℃).
