QUENCHING COOLING OIL / WATER TANK
Application & Features Quenching Cooling Tank RG-806
The products are proceeded the quenching process after heated by hardening furnace. The equipment uses a plate-type heat exchanger to control the temperature of oil rapidly. The tank is equipped with an injection cooling system; speed of injection can be adjusted freely according to the size of a work piece. A filter is installed in the tank, so the dirt is not stored in the heat exchanger; therefore, it prevents it from losing its cooling functions.

Technical characteristics of the Oil quenching bath
| Oil bath temperature | 60…80°С |
|---|---|
| Casing depth in hardening environment | 2300 mm |
| Unloading belt width | 1200 mm |
| Maximum capacity expended on heating, engines, pumps, blowers | 20,25 kW |
| The power consumed by motors | 1,5 kW |
| The amount of circulating cooling water | 78 m3/ h |
| Oil bath volume | about 13,000 liters (13 m3) |
| The residence time of products in bath | 4…20 min |
| Flat-type rollover mechanism – is a specific mechanism of patented design used for the collection of oil products and return them to the hardening bath. | |
Note: Electric heating system: for heating the heat received from the input of the hardening furnace casing is used, allowing heating oil up to 60 ... 80°C. In such cases additional heating is not required, so the sub-heaters are not necessary.

Note 1: Above capacity is according with standard height of quenching tank by 3,000mm
Note 2: In tempering furnace casing there is an oil curtain created by spraying, that prevents oil vapors from the hardening bath through the casing in a tempering furnace; At the end of the tempering furnace there is an exhaust fan, which pulls and burns the oil smoke arising in the bath hardening in oil;
