How do small vacuum quenching furnace selection

You can see in the market a lot of kinds of small vacuum quenching furnace type, if I don't know which one is more suitable for yourself, it is easy to the edition. Now, we have to support a move to you, tell you how to choose a small vacuum quenching furnace.
1, the choice of small vacuum quenching furnace heating chamber
Graphite reflector screen: the commonly used on small vacuum quenching furnace has felt hard and soft felt two kinds, suitable for general steel quenching. High temperature brazing, powder metallurgy and sintering, etc.
Metal heat insulation screen: generally used in vacuum furnace, which has two kinds of stainless steel and molybdenum. Molybdenum reflector screen is suitable for high temperature and high environmental requirements within the furnace material quenching. Stainless steel rice shoot screen is suitable for the tempering, annealing, aging, vacuum aluminum brazing, etc., some of the low temperature furnace type choice.
2, the choice of the vacuum degree
Quenching heat treatment can be used in the vacuum (generally limit p 4 x10-1 a) by using two stage pump (pump and roots pump) such as bearing steel, vacuum heat treatment of die steel, structural steel, etc.
High vacuum for some products, such as (high temperature alloy, titanium alloy, magnetic materials, such as vacuum heat treatment or high temperature brazing. Optional tertiary pump (pump before. Roots pumps, diffusion pumps, etc.) general requirements the limit of vacuum degree in 10-4 pa.
3, the choice of control system
Standard configuration: to inlet temperature controller and programmable controller as the core, realizes the programmable, manual and automatic temperature control.
Computer control system, industrial computer and programmable controller as the core process programming, storage, to make statements. Can computer independent operation, automatic, manual, process programming, etc.
: computer group control system with industrial computer as the core of many sets of vacuum furnace monitoring, collecting data, operation, report management, etc. As one of the high-tech control system.
