Designation:Vacuum
quenching oil Model:SV-Z1 SV-Z Standard:200L/cask Performance:
The important function of Vacuum quenching oilis to cool off,
shining and oxidize to stabilize; Our produces's
saturated fume press is low, cool off the function stability,
shining good, oxidize stabilize good.
Used in:
Be applicable to the vacuum quenching of the materials, such as
bearings steel, work molding tool steel and the big and medium-sized
aviation structure steel...etc..Should take off oil hollow spirit
under the vacuum when beginning use.
1 number used for the medium-sized material under the vacuum quenching.
2 number used for the material that good uenching ability under
the vacuum appearance uenching.

notice
Vacuum quenching oil forbid humidity or other oils to sneak into
in the usage, using again after shoulding sink to decline filter
over 0.03% such as the content of water.The oil should periodically
carry on the analytical monitor in the usage, according to the
actual analysis circumstance assurance whether replace or add
the new oil.Change the oil index sign as follows form.
