Description
Air-cooled vacuum oil quenching furnace is used for alloy, alloy
structure steel, mold steel, high-speed steel, bearing steel,
elastic alloy steel, stainless steel etc. to do bright quenching ,
magnetic material sintering , bright annealing or vacuum
brazing.
Technical characteristics :
·Use second-generation
graphite rod as heating element , its service life, maintenance is
much better than graphite cloth .
·Composite flashboard
valve has good insulation for heat and gas, which is much advanced
than
the flap valve .
·Adopt mechanical drive,
much more accurate and reliable than hydraulic system . Low
failure rate, simple maintenance .
·Feed mechanism :
—— For the small furnace ,
using the unique form of bifurcation **- conveying mechanism has no
oil to avoid pollution of the heating chamber and greatly reduce
the cooling chamber volume, save nitrogen for cooling , reduce the
cost of vacuum furnace operation.
—— For the big furnace,
using skip car to send oil in order to avoid deformation of
loading-box which will cause poor oil-sending.
·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 .
