Solution for determination of viscosity of quenching oil

latest company news about Solution for determination of viscosity of quenching oil  0

The viscosity of quenching oil is related to its adhesion, carrying loss and cooling performance. On the premise of ensuring the cooling performance and flash point of oil, the viscosity of oil should be as small as possible, so as to reduce carrying loss and facilitate workpiece cleaning.
Kinematic viscosity is an important index of heat treatment oil. Its change reflects the aging degree of quenching oil. Let's call it the viscosity ratio.
Viscosity ratio = Viscosity of service oil/viscosity of new oil
The ratio between the kinematic viscosity of the oil in service (40℃100℃) and the kinematic viscosity of the new oil should not exceed 1.3. The kinematic viscosity of domestic quenching oil is 15-40mm2 /s(40℃) for cold oil, and 15-50 mm2 /s(100℃) for hot oil.
