3 Technology process

in molten aluminum and aluminum alloy melt contains significant amounts of hydrogen,

metal and non-metallic slag, if before casting not in time to remove harmful substances

of the above, will be formed in the casting surface and internal porosity, slag inclusion,

loose density and other casting defects, influence the physical, chemical, mechanical

and processing properties of castings, produce a large amount of defect products. At

present, the industry recognized as the best aluminum melt refining method is the use

of rotating sprayer degassing and refining;

 

GDU casting degassing device was learned advanced technology, developed by

the development of a new type of casting degassing device, adopts currently the most

popular in the international concept of deaeration, the deaeration device placed in

casting holding furnace or ladle of converter on degassing, inert gas through applied to

turn the rotor nozzle to form a large number of dispersion in liquid aluminum small

bubbles, small bubbles of hydrogen to the diffusion, such as small bubbles rise to the

surface of the melt, achieve the goal that in addition to hydrogen, in the process of

bubbles rise at the same time, relying on the bubble surface tension of slag out of the

melt, achieve the aim of refining of melting aluminum

 

The main function of GDU series degassing device is used to remove harmful impurities

in the melt on-line refining. At the same time through turning nozzle mixing inside

molten aluminum, make the alloy elements more uniformity.

4 Main features:

4.1 degassing efficiency: GDU series degassing device design, to form the convection,

make the small bubbles in the liquid aluminum can be spread, the contact area

increases the bubble and the liquid aluminum, the equipment degassing efficiency is

greatly raised.

 

4.2 Lower using cost: GDU series casting degassing device maximum limit reduces

the equipment used in the process of power consumption, Uses the advanced graphite

rotor design, reduce the consumption of the working gas.

 

4.3 The operation is simple: GDU series casting degassing device can be used on

customer production process design, very suitable for all kinds of casting, such as: high

pressure casting, low pressure casting, as well as the gravity casting and so on, Uses

the workstation type processing, every time after the treatment, can easily will handle

ladle transferred, great place to show other processes, can improve production

efficiency.

 

4.4 It occupied an small area, convenient operation, GDU series degassing device is simple

to use, especially in workshop area the ground condition is poor, can avoid the

equipment transformation of construction work.

4.5 Simple maintenance: in the GDU series degassing device design, manufacturer fully

consider the user's maintenance costs, main control components imported components,

at the same time as much as possible the use of standard parts, easy maintenance and

replacement.

5 Structure of Moveable degassing unit

5.1 Control system: electrical control function is used to control the rotor speed in order to

achieve degassing shi slag effect optimization.Control gas solenoid valve.Display

instrument mainly include: the rotor rotational speed, all display instrument for digital

display, fault alarm.Failure occurs, the device should be able to automatic alarm, lights

flashing, to remind the operator.Equipment is equipped with operating linkage and

safety protection, to ensure the safety of operators and equipment use.Gas control

system include: inert gas pipeline, pipeline are equipped with pressure gauge, flow

regulating valve, and display instrument.

5.2 Turning nozzle through water model test results and design of the nozzle, and make the

turn nozzle structure, size and the casing cavity size optimization, air bubble produced

by small, uniform distribution, the most efficient reach deaerating effect of slag,

graphite nozzle material made from treated with anti-oxidation graphite turn nozzle, the

speed is adjustable so as to meet the needs of the process.
