Description
Vacuum  tempering
furnace
Vacuum tempering furnace is used for high-speed steel, alloy
tool steel, mold steel, bearing steel, Â stainless steel
,special alloy materials to do vacuum tempering , non-ferrous metal
recrystallization annealing or aging.
Technical characteristics :
·In order to ensure parts
quality of tempering, all models are using high vacuum system,
namely, the vacuum system consist of mechanical pump, roots pump
and diffusion pump . Ultimate vacuum can be achieved ,
6.7
×***3Pa .
·Using positive pressure
carrier gas heating , to ensure the furnace temperature
uniformity.
·High automatic control
system , stable and reliable . In addition to the loading,
discharging, all can be run automatically . For the temperature
control, intelligent temperature controller is used , for motion
control using  imported programmable controller
