Abstract: Quenching
oil based on the mineral oil results in a heavy pollution due to being
hard to be degraded. Surveys show that the mineral oil harms most to the
ground water resource, and the use and the discharge of mineral oil are
in-creasingly strictly controlled. Thus it is necessary to develop the
replacement for mineral oil, A new quench oil based on the rapeseed oil
is introduced. It is proved that the new quenching oil has great
environmental advantages and good cooling characteristics as well, and
is a hopeful substitute for prevailing quenching oil based on mineral
oil.
Key words: Quenching oil
