ALP300 Fixed Type Degasser

ALP300 Main Application

ALP300 is a fixed type integrated degasser with electric chain lifting system. As a fixed type system, it generally serves as a degassing station for  transfer ladles degassing or provide online or batch degassing for specialized furnaces. Degassing medium: 99.996% pure dry nitrogen or argon, provided by gas center and gas cylinders can be set aside the degasser.

ALP300 Mechanical Parameters

1.Fixed type, immovable, can be used as degassing station or fixed degasser for specialized furnaces.

2.Device height and travel distance can be customized according to client’s furnaces.

3.Rotor belt driven, speed from 0~600RPM, speed display adjustable, time settable and one button full-auto mode is available.

4.Lift Type: Hydraulic lift or chain lift.

5.Hydraulic type degassing arm can be manually pedal lifted when power down. Chain lift type, the degassing arm can be hand-lifted when power down.

6.Low limit position can be adjusted to adapt furnaces at different depths, or customized as double low limit switches to fit two or three furnace depths.

7.Cooling air device can cool down motor, spindle and bearing, avoiding over heat to damage the machine.

8.Good heat insulation, dry air ventilation for cooling when in continuous degassing. High frequency of usage, also need to connect to external air for cooling.

ALP300 Electric Parameters

1.Button press control panel.

2.Power: Chain Lift Type: 3-phase 380V～50Hz, 3Kw

3.Rotor speed from 0~600RPM, data display adjustable, gas flow volume 0.25～2.5Nm3/H, adjustable.

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

5.Degassing gas input pressure: 0.4～0.6MPa, auto gas replace warning when pressure lower than 0.2Mpa.

6.Manual and auto mode, switchable. 

7.Degassing time setting device: 0.01S～999H, adjustable.

8.Auto degassing under auto mode, auto-stop spinning and auto-lifting after degassing, auto-stop gas supply.

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

10.Manual emergency shut-down button.

ALP300 Advantages

1.Fixed type, no push needed, can be used as fixed degassing station for transfer ladles

2.Hydraulic type degassing arm can be manually pedal lifted when power down. Chain lift type, the degassing arm can be hand-lifted when power down to prevent consumable parts solidifying inALmelt caused by electric lift failure at power down.

3.Chain/hydraulic lift, it’s convenient for dross removal and consumable part replacing.

4.Easy-to-learn operation, manual/auto mode switchable, one button full-auto mode available.

5.Degassing time settable, auto degassing, light warning after degassing and auto-elevation.

6.Minimum manpower involvement.

7.Efficient usage of nitrogen or argon, less degassing time, automatic degassing.

8.High efficiency degassing, more homogenized melt.

9.Remarkable degassing effects, higher casting yield, improving casts mechanical performance.

10.Best rotate speed and gas volume setting available according to the various melt density.

11.Compact and durable, low cost maintenance.

12. Customized heat insulating covers to reduce heat loss.

ALP300 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.
