Nitrogen degassing aluminium is used for gas blowing refining, it has the characteristics of convenient operation, environmental protection and safety, and low cost, but the refining effect is restricted by the purity of the inert gas itself. Generally, inert gases will always contain a certain amount of moisture and oxygen even if strict purification measures […]
Aluminum degassing system adopts a dual-rotor gas refining device, which refining gas is blown through the rotating nozzle to generate tiny bubbles. The rotating nozzle is made of graphite. The nozzle structure design takes into account the uniform ejection of bubbles. The rotating impeller is also used to break the bubbles, increase the contact area […]
In order to improve the purification treatment effect for continuous casting and ensure the stable and reliable melt quality, the molten aluminum adopts a combination of continuous purification treatment inside and outside the furnace. Purification Treatment for Continuous Casting The main function of the on-line refining treatment device outside the furnace is to refine crystal […]
Aluminum degassing units can reduce gas accumulation and problems and achieve the highest refining efficiency. Online degassing unit adopts advanced high silicon melting technology to get a long service time, degassing rotor, heater protection thimble and thermocouple protection thimble adopt ceramic manufacturing technology. Aluminum degassing units are used for hydrogen (H) and slags removal from […]
Online purification equipment is an advanced melt purification method. The aluminum melt of primary aluminum, scrap, and remelted waste must be purified before being cast into ingots, slabs or rods. This can be accomplished by blowing non-chemically reactive gases such as nitrogen or argon into the aluminum melt. In most cases, a halogen gas is […]
AdTech offers Rotary Degasser and flux for molten aluminum degassing. In the rotary degassing method, inert or chemically inert gases (argon, nitrogen) are removed through the rotating shaft and rotor. The energy of the rotating shaft leads to the formation of a large number of fine bubbles, thus providing a very high surface area to […]
Turbulence or agitation of the melt and increased holding temperature significantly increase the rate of hydrogen solution, oxidation, and transient element loss. The mechanical properties of aluminum alloys depend on casting soundness, which is strongly influenced by hydrogen porosity and entrained nonmetallic inclusions. The aluminum foundry needs to degas and filter inclusions by Online Degassing […]
