ALUMINUM DEGASSING
Aluminum degassing with rotor effect pump
This degassing technology allows to obtain a very high degassing efficiency because by sucking the metal of the bottom of the containment basin by pump effect, it is able to treat all the metal contained in the basin (with traditional rotors, the area between the bottom of the basin and the base of the rotor is not crossed by the gas bubbles and thus not treated).
​
This result is obtained through the rotor that with its shape, during rotation sucks the metal from the bottom of the basin expelling it from the side cavities, mixed with the treatment gas in the form of bubbles with small dimensions and well distributed.
​
Rotor size:
diameter 250 mm
height 80 mm
fillet on request
plants and products for foundries
We can obtain the following advantages, with the pump effect created by this rotor:
-
reduction of degassing cycle times
-
reduction of the heat loss of the metal, with a shorter degassing cycle
-
increase in the density value of the treated metal
​
Automatic control and gas management panel
-
Device that allows the display of the gas pressure contained in two different bottle gas.
-
It uses the output voltage of the pressure reducer transducer or adapters available for this purpose.
-
Entirely programmable as in the standard OB-OXID version, this device also allows you to view the low pressure through an additional display, for managing the quantity of gas output in m2 / h, with an alarm signal if the quantity of mtq / h falls below the minimum set value.
-
Available in the EASY and AUTO versions, the AUTO version allows you to activate the OB OXI SWITCH bottle gas exchanger in manual or automatic form.
-
High precision and great visibility thanks to the value displayed in numerical and graphic form.
-
Equipped with alarms for the detection of faults and absence of gas in compliance with the IEC60601 standard Equipped with alarm silence circuit for a maximum period of 3 minutes.
-
Possibility to deactivate the device when the vehicle is out of order (in case of control, vehicle overhaul)
-
The device has a special function for periodic verification of correct operation and the absence of faults.
-
It can also be connected to other types of gearboxes provided that the appropriate adapters are used.
-
Possibility to remotely remote empty cylinder alarms in the cockpit.
-
Check the supply voltage.
-
Equipped with two OB OXIR 40 SENS pressure reducers.
-
Power supply from 9 to 28 Vdc.
-
24-month warranty if it is not tampered with, modified or altered by the user.
-
Approved according to the Medical Directive 93/42 / EEC and according to the European regulation ECE R.10.
-
Easy connection to the cylinder exchanger and pressure reducers of the OB OXIR 40 SENS family.
-
Possibility to exclude some specific functions
Degasystem base
Portable degassing system, very light and compact, small size. The right compromise for a good degassing in safety with a small investment.
Degasystem plus with fixed column
Automatic plant for degassing and insufflation of the salt for the slagging, automatically and safely with repetitive cycles in the ladles or in the crucible furnaces.
Portable trolley on wheels, shaft holder for degassing
Trolley for degassing tube with porous septum with manual vertical movement with fixed positions on vertical position.
GRAPHITE TREE
Impregnated graphite shaft for degassing of small quantities of aluminum.
Advantages degassing with a porous septum tube.
-
much smaller gas bubble and better control
-
better gas distribution also towards the crucible wall
-
greater quantity of treated metal
-
low turbulence in the bathroom surface
-
lower gas consumption
Disadvantages degassing with only tube or pads.
-
much more large and turbulent bubble
-
greater turbulence on the surface of the bathroom
-
less thrust of the bubble towards the crucible wall
-
low dispersion and less quantity of treated metal
-
higher gas consumption
