Aluminium 7075 Molten Metal Filtration has the characteristics of high temperature resistance, corrosion resistance, melting metal corrosion resistance, high strength, high qualification rate and large specific surface area. Mainly used for filtration and purification of metallurgy and casting melting aluminum.

The molten metal mixture flows through the porous structure of the ceramic foam, thereby becoming uniform, smooth and clean.

Aluminium 7075 Molten Metal Filtration

Features of aluminum alloy Ceramic foam Filter for casting

1. High air permeability, good strength, good thermal shock resistance, stable quality, no matter the large size or small volume ppi product, there is no loss of impurities under high temperature.

2. Advantages compared with traditional filter materials: thermal stability and chemical stability at high temperatures, to avoid chemical reactions with molten metal after filtration.

3. Pure ceramic composite materials have high porosity and good high temperature mechanical strength.

4. Fully open pores, ceramic particles or powder will not be lost during the filtration process (snowfall).

5. Convenient operation and energy saving. Make the metal flow smoothly, avoid sputtering and reflow, thereby improving the surface quality of castings, preventing hole deformation, and ultimately reducing the rejection rate.

Aluminium 7075 Molten Metal Filtration is a very effective tool for Aluminium 7075 purification to obtain the purity of molten metal in the casting process. It is characterized by good thermal conductivity, good stability, and resistance to sudden changes in temperature.

The foam aluminum ceramic filter adopts the adsorption principle, which can effectively remove large and small impurity particles without falling debris, effectively reducing the pollution of molten aluminum.

Excellent thermal shock resistance, improve the corrosion resistance of molten metal, can stabilize the flow of aluminum, facilitate the filling of castings, reduce slag and pinhole defects, and improve the quality and productivity of aluminum alloys.

Ceramic foam filtration method

Ceramic foam filter is made by injecting a mixture of alumina and phosphate into sponge plastic, and then drying to volatilize the sponge plastic. It can also be called a microporous reticulated ceramic foam sheet with a sponge-like structure.

When the aluminum melt flows along the tortuous channel and the pores of the filter plate, the inclusions deposited on the inner surface contact the pores, inertia, flow force, and retained filter material, and maintain the surface and gap of the internal pores.

The inclusions remain in the filter material and are separated from the molten aluminum.

Foam ceramic filter plate is easy to use, good filtering effect, low price, and it has been widely used in the world. Filter the molten metal with ceramic foam filters.

The thickness of the foam ceramic filter plate is generally 50mm, the length and width are 200~600mm, and the porosity is as high as 8%. The filtration does not require a high-pressure water head, the initial size is 100-150mm, the latter only needs 2-10mm.

The Ceramic foam Filters is surrounded by a gasket between the filter and the filter box to prevent molten aluminum from leaking from the interface.

Our Ceramic foam Filter uses two different types of sealing gaskets, fiber cotton gaskets and expanded cotton materials.

initially, the number one classification of scrap aluminum is executed and stacked in grades, along with pure aluminum, wrought aluminum alloy, porous-ceramic-filter-product
out, and mixed substances.

For waste aluminum merchandise, it has to be disassembled to take away the metallic and different non-ferrous metallic parts linked to the aluminum fabric, after which wash, overwhelm, magnetic separation, dried, and other methods to make waste aluminum.

The liquefaction and separation of scrap aluminum is the development direction of recycling aluminum metal within the destiny.

It combines the pretreatment of scrap aluminum and re-casting, which no longer handiest shortens the method glide, but also avoids air pollutants to the finest quantity, and greatly improves the recovery price of the internet steel.

The device has a porous-ceramic-filter-product
that lets gasoline particles skip through. in the liquefied layer, aluminum precipitates at the lowest, and naturally depending on with paint attached to the waste aluminum is decomposed into gasoline, tar, and solid charcoal at 450 ℃ or greater.

Then complete combustion via the oxidation device inside the separator. The waste is stirred by a rotating drum, blended with the dissolved liquid inside the bin, and impurities which include sand and gravel are separated into the sand and gravel separation area, and the dissolved water finished by way of the waste is returned to the liquefaction bin thru the recovery propeller.

in keeping with the training and great fame of scrap aluminum substances, and in accordance with the technical necessities of recycled products, pick and suit and calculate the variety of numerous materials.

substances must take into account the degree of metallic oxidation burning loss. The oxidation burning loss of silicon and magnesium is bigger than that of other alloying elements. The burning loss fee of various alloying factors must be determined earlier thru experiments.

The bodily specs and floor cleanliness of scrap aluminum will without delay affect the quality of recycled merchandise and the real metal recuperation price.

For waste aluminum which isn't always easy from oil removal, up to 20% of the powerful ingredients will input the slag. Recycled wrought aluminum alloys. Wrought aluminum alloys that can be constituted of scrap aluminum alloys encompass 3003, 3105, 3004, 3005, 5050, and so on., of which 3105 alloy is in particular produced.

in an effort to make certain that the chemical composition of the alloy cloth meets the technical requirements and pressure processing manner necessities, part of number one aluminum ingots have to be introduced when important.

handiest a small part of recycled cast aluminum alloy scrap aluminum is recycled into the deformed aluminum alloy, and about 1/4 is regenerated into deoxidizer for steelmaking, most of which can be used for recycled forged aluminum alloy.

most effective a small part of scrap aluminum is recycled into the wrought aluminum alloy. The die-forged aluminum alloy A380, ADC10, etc., which are widely used in the USA, Japan, and other international locations, are basically recycled from scrap aluminum.

the primary system for secondary aluminum normally uses a devoted static furnace with oil or gas.
