Degassing unit

The on-line degassing equipment mainly deals with molten aluminum which contains a certain amount of hydrogen and other residues(alkali metals, inclusions).
The principle of on-line degassing equipment is gas flotation principle with the process gases (inert gas or mixture of inert gas and chlorine gas). The rotor takes the process gasses into molten aluminum and smash the gases into dispersed tiny bubbles and the bubbles rise to molten aluminum surface
1.Hydrogen is being absorbed into bubbles and is being removed.
2.Alkali metals are removed as the metals react with chlorine gas to form chlorides.
3.The inclusions are trapped by bubbles and then rise to the surface of the melt to form dregs

Product name Model:Online degassing Degas-AOE
between furnace and casting equipment. It is used for hydrogen (H) and slag removal from molten aluminum. The online degassing unit has dual functions: processing and heating. It provides purification for high precision molten aluminum used for computer HD, photosensitive drum for color and black- and-white photocopier, micron aluminum foil blank, PS substrate for printing, can stock, landing gear, Intercrystalline high.

Hydraulic lifting

Outer wall temperature of online degassing device should be controlled at 65t or below.
The sealing structure is designed by fully sealing the box cover, the box body and the aluminum melt inlet and outlet. It can effectively prevent the slag from the secondary oxidation of aluminum melt and improve the degassing effect.

Assembly principle and structure design
The on-line degassing equipment has an ultra-long life and the furnace body adopts the new manufacturing technology of high fused silica. The degassing rotor, heater protection sleeve and thermocouple protection sleeve are made of silicon nitride (Si3N4) ceramic with high technical performance of aluminum production technology.
Standard design of box抯 quality & structure
The inner lining is made of high fused silica, and the life of the inner cavity is 2 years on average (up to 3 years). Non-stick aluminum, no pollution to molten aluminum. The inside design has a baffle plate to ensure the stability of the surface for molten aluminium, which can prevent air and the oxide on the surface of molten aluminium from being rolled and bubbles or residues flows out.

Rotor standard design
Using silicon nitride material, the service life is more than 2 years. The design of stepless speed control of 0-600 rpm can break the bubble to the maximum extent, and spread the bubbles throughout the inner cavity.
Immersion heater protection sleeve
Using silicon nitride material, the average service life is 1 year or up to 2 years. High heating efficiency and the surface oxidation is reduced and the pollution of slag
