ALP320 Fixed Type Square Column Degasser

ALP320 Main Application

ALP320 is a mechanical-electrical separated fixed type square column degasser equipped with dual-chain lift. Square column as support features a firmer structure, and dual-chain lift, smoother up & down. System is designed especially for extra high furnaces or furnaces placed on platforms. Electric control and degasser are separated for better control. Degassing medium: 99.996% pure nitrogen or argon, provided by gas center and gas cylinders can be set aside the degasser.

ALP300 Mechanical Parameters

1.The system adopts square columns as support, fixed type and immovable. Electric driven degassing arm and dual-chain driven lift.

2.Device height and travel distance can be customized on demand. This system is generally specialized for high-position furnaces.

3.Al Cable carrier protected power cords and gas pipes.

4.Rotor belt driven, speed from 0~600RPM, data display adjustable, time setting available and one button full-auto mode available.

5.Degassing arm can be manually lifted when power down.

6.Low limit switch position can be adjusted to adapt furnace depth.

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

8.With good heat insulation and air cooling by independent cooler fans, the system can be applied to continuous degassing too.

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

10.Manual emergency shut-down button.

ALP320 Advantages

1.Square columns as support, higher machine can be customized, more suitable for high-position furnaces degassing.

2.Fixed type, can be controlled by separated control box, one device for one furnace.

3. Manual handle is equipped to elevate degassing arm to prevent consumable parts solidifying inALmelt caused by electric lift failure at power down.

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.

ALP320 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.
