THI^®F-512 Gear quenching oil

①rapid steam film stage, fast cooling rate at high temperature, slow cooling rate at low temperature. It can effectively reduce the change of tooth profile, tooth trace and flatness during the quenching process of the gear, while obtaining high and uniform surface hardness and sufficient hardening depth.
②the quenchant has good thermal stability, long service life and long-term stable cooling characteristics.
③The product has little smell, smoke and carbon deposit. the surface of the workpiece is easy to clean and has fine luster after quenching.
④high-quality base oil is used to make the quenching oil, the wastage is extremely low, the amount of carry-out is small, and the cost of use is low.

THIF-512A gear quenching oil is suitable for small and micro gears which have high deformation requirements;
THIF-512B gear quenching oil is suitable for light and medium-duty vehicle gears, motorcycle gears, mini-vehicle gears, synchronizer gears, transmission gears, etc.

512A applicable temperature: 90℃-100℃ (open oil tank), 100℃-140℃ (closed oil tank)br> 512B applicable temperature: 70℃-90℃ (open oil tank), 80℃-110℃ (closed oil tank)

①Quenching tank: The sludge, oxide scale and carbon black should be removed from the quenching tank before use, and there must be no water in the quenching tank.
②Moisture control: Be careful not to mix in moisture. If more than 400PPM of moisture is mixed in during group quenching, it may cause uneven quenching hardness and reduce the service life of quenching oil. If there is moisture, dehydrate first.
③Control of oil temperature: use instruments to monitor and control the oil temperature to keep the oil temperature within the recommended temperature range. The quenching tank should have cooling and heating devices. When choosing a cooler, it is better to choose an air cooler. If you choose a plate heat exchanger, you must ensure that the heat exchanger does not leak (note that copper or copper alloys have an aging effect on the quenching oil and cannot be used as a radiator). On the premise of meeting the quenching requirements, try to choose a lower oil temperature to extend the service life of the quenching oil.
④String control: Propeller string is the best, followed by circulating oil pump, preferably not using air pump to stir. Set appropriate stirring force according to the material, shape and size of the workpiece.
⑤Regular cleaning of impurities: the scrap iron, oxide scale, oil sludge, oil residue and other impurities in the oil tank and circulation system should be regularly precipitated, filtered and cleaned to keep the quenching oil clean.
⑥Notice: thick and large workpieces must be quickly submerged in quenching oil. If the workpiece is half in oil and half in the air, it is likely to ignite the quenching oil and cause uneven hardening of the workpiece.
⑦ detection: regularly inspect the viscosity, flash point, water content and cooling characteristics of the quenching oil, and timely replenish the quenching oil in the oil tank.
