ALP600 Triple-Rotor Online AL Melt Degasser


ALP600 Main Application


ALP600 is a 3-level online degasser with triple rotors and 90° swing angle. This system can be installed on special designed degassing launder for online continuous degassing, suitable for continuous or semi-continuous casting. The 3 rotors can be lifted and controlled independently. The launder bowl is embedded baffles to form and separate independent degassing sections. Rotors can be lifted individually for consumable parts replacement without interfering other rotors’ degassing. The degassing box is opened with 3 dross-removal windows, no interfering to degassing. The system fits furnaces with a capacity of15 Kg/HALmelt flow. Degassing medium: 99.996% pure dry argon or nitrogen, can be provided directly by gas center.


ALP600 Mechanical Parameters


1.The system can be designed as non-swing type or with a 90° whole swing angle.

2.Triple-rotor design, same rotation, rotors control rotation speed and gas flow independently.

3.Rotors and heat insulation cover can be lifted as a whole, meanwhile, rotors can be separated with the heat insulation cover. Consumable parts can be replaced for individual rotor and separate rotor installation and maintenance with no interference to other rotors at degassing.

4.Electric chain lift.

5.Fast connectors for power and gas circuit.

6.System is set with a special dross removal window, with no interference to degassing.

7.External dry air connection interface for air cooling fans, spindle and bearing.

8.Taper hooks above each rotor, convenient for single dismantlement and maintenance.


ALP600 Electrical Parameters


1.Mechanical-electrical separated, button press control box, remote control available.

2.Power: 3-phase 380V50Hz, 5Kw

3.Rotor speed control from 0~600RPM, data display adjustable,

4.Separate setting for each rotor gas flow. Volume: 0.252.5Nm3/H, adjustable.  

5.Degassing Medium: Industrial dry nitrogen or argon, 99.996% pure.

6.Degassing gas input pressure: 0.40.6MPa, auto gas replace warning when pressure lower than 0.2Mpa.

6.Manual and auto mode, switchable. Warning light alert and alarm when degassing time ends. 

7.Degassing time setting : 0.01S999H, adjustable.

8.One button full-auto mode available after parameter setting.

9.Manual emergency shut-down button.

ALP600 Advantages


1.Triple-rotor 3-level degassing, capable to degas moreALmelt, higher efficiency. Independent rotor control, with higher degassing effects.

2.Electric lift, more convenient to replace consumable parts. Rotors can be dismounted separately, easy maintenance.

3.Mechanical-electrical separated, remote control available. Special dross removal window, no interference to degassing.

4.Press control, easy and convenient, manual/auto mode switchable, no man supervision required in auto mode.

5.User defined degassing time: 0.01S~999H. Warning light alert and alarm when degassing time ends.

6.Efficiently use of nitrogen or argon, less degassing time and degassing automation.

7.3-level degassing for higher volume ofALmelt. High efficiency degassing, more homogenized metal melt.

8.Remarkable degassing effects to raise yielding rate of casting and improve cast mechanical performance. 

9.Best rotate speed and gas volume setting available according to the various melts density.

10.Compact and durable, low cost maintenance.

ALP600 Degassing Principles


Inject pre-set quantity of inert gas into theALmet through rotating graphite shaft and rotor. The rotor disperses the inert gas into millions of small bubbles, evenly into the melt. Small inert gas bubbles capture hydrogen and nonmetallic impurities, then altogether flow to the melt surface.
