DATA AND SPECIFICATIONS OF BATH HARDENING IN OIL

 

BATH HARDENING IN OIL RG806, consists of the following components: BATH HARDENING IN OIL
  • Casing with a flame curtain device;
The operating principle of a flame curtain:
    • 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;
  • The conveyor belt of heat-resistant wire links to unload products from the bath hardening in oil.
  • SWEP outer heat exchanger (Sweden) -performance 100RT (RT-refrigerated tons).
  • Heat load
304000 kcal / h
  • Total heat exchange area
10.4 m2
  • Water flow rate
60912 m3/ h
  • Oil flow rate
31320 kg/ h
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.
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.
