China Online Degassing Device For Aluminium manufacturers
1 Product name : Moveable degassing unit for aluminium melting and casting 2 Product appearance: 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. gh 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.China Online Degassing Device For Aluminium manufacturers website:http://www.chinaceramicfilter.com/online-degassing-device-for-aluminium/
