QUENCHING COOLING OIL / WATER TANK

Furnace line for heat treatment of conveyer type

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;
