hot-bath quench oil | | ¢ñ.speciality
| | The
product is based on prepared thick fractionated lube, fixed with many kinds of
good additive, such as complex bearing-hot-temperature anti-oxidant, cooling additve,
dispersant. The oil is steady and not be oxidated. The quality is on the same
level of the same kind of product-same-temperature classified quenched oil made
by Japanese lube company. When new oil is used in proteceted-atmosphere heating
stove, it will bright surface of quenched workpiece. Especially to quenched workpiece
whose dimension precision is asked to be great, such as auto and truckmotor gear,
beaing furrule, the oil will reduce trend of heating transfiguration distinctly. |
| ¢ò.
purpose | | It
is used commonly to martensite same-temperature classified quenched craftwork.
It can be collacated with import heating-dealing product line required hot oil.
| |
¢ó.usage | | The
product cannot be used under the temperature of 100¡æ. The right temperature scope
is 120-160¡æ. If you want improve the oil's cooling capability, you can improve
beating up intensity in oil slot. when use oil, we will prevent water. If it is
possible, the filtrate setting will be installed in circular managing line. After
a year, once three months, we will sample to analyse and test old oil to confirm
if it is required to change oil. | | ¢õ.quality
