The choice of vacuum heat treatment furnace vacuum furnace heating chamber type

The choice of vacuum heat treatment furnace vacuum furnace heating chamber type

The graphite type screen (hard and soft blanket) :
Applicable to the general steel quenching furnace, annealing furnace, etc. Also suitable for high temperature brazing, powder metallurgy material, ceramic material of sintering, etc.
Metal screen type (mo) :
Suitable for higher environmental requirements in the furnace materials (such as high temperature alloy, titanium alloy, stainless steel, magnetic materials, etc.) quenching, quenching, annealing; High temperature vacuum brazing and sintered powder injection molding products.
Metal screen type (stainless steel) :
Applicable to the tempering, stress relieving, aging and vacuum aluminum brazing furnace at low temperature.
The composite panel type (metal + ceramic fiber or graphite felt) :
Inner surface scouring, use between metal and graphite plate.
The choice of control system
Standard:
To inlet temperature control instrument and the temperature of the programmable controller as the core can be turned into and automatic control, the economy is applicable and reasonable allocation.
The computer control system:
With industrial computer as the core set of process programming, storage, reporting, etc. As one of the single control system. In intuitive, large storage, easy to operate.
Computer group control system:
With industrial computer as the core set of data acquisition, process programming, storage, report management, etc., as one of the many sets of vacuum furnace and other heating furnace of centralized control system.
The choice of the vacuum
General materials (such as structural steel, bearing steel, tool steel and die steel, etc.) of the vacuum heat treatment can be used in vacuum (pa) ultimate vacuum 4 x 10-1.
Higher requirements for materials, such as titanium alloy, magnetic materials, high temperature alloy, stainless steel, etc.) of the heat treatment and brazing, can choose high vacuum (ultimate vacuum for more than 4 x 10-3 pa); Should choose higher vacuum degree of vacuum aluminum brazing furnace 10-4 (pa).
