Vacuum furnace selection

Vacuum furnace selection

A, vacuum heat treatment furnace according to use can be divided into vacuum quenching furnace, vacuum tempering furnace, vacuum annealing furnace, etc.
1, vacuum quenching furnace; Vacuum quenching furnace can be divided into the vacuum oil quenching furnace and vacuum gas quenching furnace.
1, 1, 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 materials, hardenability is strong, the cost is low, the quenching oil can be reused. Deficiencies; The deformation relative to a few bigger, workpiece needed after cleaning. Vacuum oil quenching furnace and three from the structure can be divided into double chamber furnace chamber furnace, etc.
1, 2, vacuum high-pressure gas quenching furnace is suitable for high speed steel, stainless steel, die steel and some other better material of vacuum heat treatment of hardenability, characterized by small parts deformation, do not need to wash after heat-treatment. Deficiencies have quenching gases cannot be recycled, the cost is higher. Vacuum high-pressure gas quenching furnace from the structure 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. Vacuum high-pressure gas quenching furnace quenching pressure is commonly 2 b a r ~ 10 b r a. According to the needs of the user can select parts is suitable for the pressure of furnace type.
2, vacuum tempering furnace, vacuum tempering furnace can be divided into the single room, double room, and vertical generally USES nickel chrome with highest heating temperature is 800 ℃. Vacuum tempering furnace generally applicable requirements after tempering parts surface light, no oxidation color.
3, vacuum annealing furnace, vacuum annealing furnace can be divided into single rooms, double rooms and vertical. Vacuum annealing furnace according to the parts material can choose the high, moderate and low temperature (high temperature 800 ℃ ~ 1350 ℃, low temperature 800 ℃).
