Inline Degassing Equipment -sales@aluminiumceramicfiber.com

Inline degassing equipment mainly processes molten aluminum containing a certain amount of hydrogen and other residues (alkali metal, inclusion of slag), which are removed after being processed by degassing equipment. The principle of inline degassing equipment is the principle of gas flotation.

Process gas (inert gas or mixture of inert gas and chlorine gas) is injected into the melt through the rotor and broken by the rotor into evenly dispersed microbubbles, and the microbubbles rise to the melt.

The hydrogen is adsorbed in the bubble and excluded.

The alkali metal is eliminated by chemical interaction with chlorine (formation of chloride);
The inclusions are trapped by the bubbles and then rise to the surface of the bath to form dross.

Inline Degassing Equipment

The degassing efficiency of the degassing box is stable at 60% on average, and when the aluminum to argon liquid is less than or equal to 1%, the best degassing effect can reach 0.09 cc / 100g.

The inner liner is made of molten material with high silicon content. The service life of the internal cavity is on average 2 years, up to 3 years. The non-stick aluminum effect is good. It has no pollution to cast aluminum. The interior design has a baffle to ensure the stability of the aluminum melting surface. It can prevent the oxides on the surface of air and cast aluminum from being coiled into the cast aluminum, and bubbles or residue will flow out.

The rotor is made of silicon nitride and has a lifespan of over 2 years (the longest lifespan can be 5 years). It has the strong corrosion resistance of aluminum, thermal shock resistance, oxidation resistance, wear resistance, and mechanical strength. Superiority, long-term immersion, using 60mm pole and 200mm head diameter, can minimize the resistance to agitation of cast iron; 450-550RPM high speed design can break the bubble to the maximum. (stability of degassing efficiency, service life, labor cost to replace the rotor, etc.) The overall cost performance is the best.

It adopts silicon nitride material and has an average lifespan of 1 year and up to 2 years. The heating efficiency is high, the surface oxidation of the aluminum casting is reduced, and the slag is not polluted by aluminum water.

The degassing device can be used with an optional mixture of argon, nitrogen and chlorine, and it is safe to use argon and chlorine protective measures.

The sealing structure of the in-line degassing device is designed to completely prevent the slag generated by secondary oxidation of the aluminum casting by the design of the tank cover, the can body and the orifice of the tank. aluminum smelting, and effectively improves the degassing effect.
