Molten Ceramic foam Filter Kamensk Aluminium is made on the basis of a carrier with a rigid network structure and combined pores of organic ceramic foam filter.
The production process is as follows: the carrier is placed in the thixotropic alumina slurry, the automatic extrusion process is adopted, and the center square is corrected to make the slurry evenly settle in the carrier foam skeleton.
After the carrier is dried and hardened, the final product is made by frying at a high temperature of 1180°C.
The filter is installed in the filter housing to filter out the impurities in the molten aluminum alloy, which helps to meet the requirements of high value-added, high-tech precision aluminum alloy castings.
For example, computer hard drives, PS bases for printing, canned materials, turbojet fan blades, etc.

RUSAL recently stated that it may restrict aluminum exports after the Russian government starts to impose export taxes and fees next month.

Roman Andryushin, the company’s head of domestic and Chinese market sales, said that the company exports about 3 million tons of aluminum each year. This year’s exports may be reduced by hundreds of thousands of tons, because the taxation will make some exports unprofitable.

Russia announced in June that it would impose at least 15% taxes on exports of steel, nickel, aluminum and copper (tax rates vary) from August 1 to curb the surge in commodity prices and boost treasury assets. The Russian government stated that the taxation that lasts until the end of the year will be temporary, and that more sustainable measures will be sought afterwards.

Andryushin believes that the taxation is unfair, because the company will invest billions of dollars to modernize the smelter, and the tax will not significantly reduce local prices, because aluminum accounts for the cost of the Russian construction industry (including state-owned projects) The ratio is relatively small. He also pointed out that Rusal supplies high value-added products to the Russian domestic market and has signed long-term sales contracts.

It is reported that Rusal is unlikely to pass on tax costs to customers, partly because it cannot include these taxes in most long-term agreements. Andryushin said: “If we do this, the market may not buy it, and we will not pay for it. ”

Andryushin said that the tax may mean that Rusal is considering suspending some unprofitable production, and the start of the new Taishet project may be slower than previously expected.
In addition, Rusal expects that aluminum demand will continue to be strong and prices may rise, but may not reach the historical high of more than 3,300 US dollars per ton. The company expects that domestic aluminum sales in Russia will jump 20% this year to 1.2 million tons. Due to economic recovery, major aluminum powers’ measures to restrict supply, and the prospect of increased demand in the electric vehicle and new energy industries, aluminum prices have risen by about 23% this year.

Molten Aluminum Ceramic foam filters Russia Aluminum are used to filter molten aluminum. The foam mesh filter uses alumina aggregate particles as the binder phase, and is usually used to filter aluminum and aluminum alloys.

In the aerospace, electronic communications, and food packaging industries, more and more stringent requirements are placed on the quality of aluminum products. For example, even if there are several surface defects that strongly affect it, it must remove molten aluminum as much as possible from the smallest inclusions in the alloy material.

The aluminum liquid secondary purification device is provided with two filter chambers at the bottom of the filter chamber.

In the first chamber, the molten aluminum impurity coating is removed, and the molten metal is fed into the mold to keep the second chamber clean.

The molten aluminum flows into the second chamber through the first chamber in the filter chamber.

Almost no molten metal oxide is formed here.

The aluminum liquid purifier has a rod heater to keep the temperature of the molten metal within a strictly controlled range. In this way, an easy-to-replace filter can be used to effectively remove impurities from the molten metal.

Molten Aluminum Filter Russia Aluminum uses a three-dimensional network structure and organic foam with bonding pores as a carrier to penetrate the thixotropic alumina material slurry.

Using a fully automatic extrusion process with square center distance correction, the slurry is evenly distributed on the foam carcass, sintered and cured at a high temperature of 1180°C.

Installed in the filter housing, used to filter impurities in the aluminum alloy liquid, to meet the needs of high-tech aviation and transportation of high value-added precision aluminum alloy casting filter.

Such as: computer hard disk, PS board base for printing, canned food, jet turbofan blades and other products.


Ceramic foam filter plate gasket for alumina filter manufacturing

There are gaskets around the ceramic filter plate acting on the contact surface of the filter plate and the filter box to prevent the aluminum liquid from leaking through the contact surface.

Ceramic Foam Filter For Aluminium uses three different characteristics of the gasket: fiber paper edge; cotton fiber edge; lengthened cotton hem.

RUSAL announced the mailbox of the alumina filter plant of the Egyptian aluminum smelter and aluminum foundry.

Data released by the customs of the Russian Federation showed that Russia’s exports of aluminum increased from January to June, while exports of nickel and copper declined.

Bulgaria China Foundry Ceramic foam Filter can filter non-metallic impurities and oxide film (commonly known as slag) in molten aluminum.

Choose a Ceramic foam Filters plate and observe its color

Pure color, variegated color, uniform material.

On the other hand, hold the filter plate with one hand, tap the filter plate gently, and tap the filter plate appropriately.

The ceramic slag is continuously lost. The inferiority of the filter plate is obvious, and the aluminum liquid causes secondary pollution.

Use open flame and electric heating to burn to red, and immediately cool to room temperature without tilting or wearing. It is said to be a good filter plate.

AdTech has a complete quality control system for ceramic foam filters, including technical standards, testing equipment and testing methods to achieve product quality control requirements.

The molten aluminum ceramic foam filter plate is a new type of filter plate made of industrial sponge as a carrier, filled with heat-resistant ceramics and then sintered.

Due to the combined action of the axial pressure, friction and surface adsorption of the molten aluminum, it is retained on the inner surface of the ceramic filter plate and the gap cavity, thereby separating the slag and the molten aluminum.

Cast aluminum and aluminum alloys are aluminum castings produced by casting methods. Deformed aluminum and aluminum alloys are processed products produced by pressure processing methods.

The quality of aluminum ingot raw materials directly affects the quality and production efficiency of aluminum alloy die castings.

Good raw materials can reduce mold wear, extend mold life, reduce costs, and improve production efficiency.

Bulgaria Aluminium introduces Bulgaria China Foundry Filter from China has the following advantages

1. Alumina ceramic foam filter effectively removes solid inclusions in molten metal, so that aluminum alloy can be smoothly forged, aluminum foil manufacturing, extrusion processing, etc., and perfect aluminum can be obtained.

2. The ceramic foam filters can reduce the turbulence of the molten aluminum and purify the molten aluminum.

3. The filtered and purified aluminum castings can significantly extend the service life of parts with high demand such as aviation and auto parts, and also have a good effect on aluminum parts that require surface polishing.

4. Ceramic foam Filters also play an important role in traditional aluminum industry, electrical aluminum industry and continuous casting and rolling processes.

Aluminum Billet Ceramic foam Filter removes the debris from the molten aluminum, effectively improving the economic benefits of the aluminum rod factory. Larger inclusion particles can be removed from molten aluminum, while inclusion particles of 100 μm or smaller account for most of the inclusions and are difficult to remove.

In particular, it is difficult to remove fine inclusion particles around 10-25 μm, but this is a necessary condition for obtaining high-quality aluminum alloys.

In order to remove such fine inclusions, the traditional filter needs to have a finer mesh.

However, when the filter screen is too fine, when the molten aluminum contains a large amount of inclusions, there may be a practical problem that the filter screen is clogged during short-term operation, resulting in a shortened life of the filter screen.

Therefore, in the case of using aluminum scraps of such aluminum alloy products as part or all of the aluminum raw material, it is necessary to remove the inclusions at least from the molten aluminum obtained by melting the aluminum raw material. Therefore, in addition to the refining process of degassing the molten aluminum using a flux, a filter is also used to remove the inclusions in the molten aluminum.

Inclusions refer to some refractory foreign substances with high melting points in the aluminum melt. Inclusions are a common phenomenon in the production of aluminum castings.

Inclusions can be divided into solid inclusions and liquid inclusions, and their particle size ranges from a few microns to a few millimeters.

If these inclusions are not removed cleanly, they will form large defects in the aluminum alloy. They often cause stress concentration and cause the casting to be scrapped. It not only affects the mechanical properties, cutting performance, and corrosion resistance of the casting, but also causes porosity in the casting. And other defects.

Aluminum Billet Ceramic foam Filters can remove impurities in aluminum melt and improve the quality of aluminum ingots, aluminum rods, and aluminum plates.



Aluminum rod is a kind of aluminum product. The melting and casting of aluminum rod includes melting, purification, impurity removal, degassing, slag removal and casting process. According to the different metal elements contained in aluminum rods, aluminum rods can be roughly divided into 8 categories.

Melting and casting include melting, purification, impurity removal, degassing, slag removal and casting processes. The main process is:

(1) Ingredients: According to the specific alloy grades to be produced, calculate the addition amount of various alloy components, and reasonably match various raw materials.

(2) Smelting: The prepared raw materials are melted in the melting furnace according to the process requirements, and the slag and gas in the melt are effectively removed by degassing and slagging refining methods.

(3) Casting: Under certain casting process conditions, the molten aluminum is cooled and casted into round casting rods of various specifications through a deep well casting system. Ceramic foam Filters

5052 ceramic foam filter for Molten Alu plays a very important role in improving the quality of castings.

It can effectively filter liquid-solid non-metallic inclusions in molten metal once or twice, thereby reducing slag holes, improving the mechanical properties of castings, reducing machining allowances, improving surface finish, and prolonging the service life of castings.

If the molten aluminum ceramic foam filter is used improperly, the effect is worse than other filters.

The filtration area of ??5052 Aluminum Filter for Molten Alu should be large enough to not affect the flow rate of aluminum alloy melt.

There should be enough space before and after the filter to collect inclusions.

The molten aluminum alloy should be melted in a melting furnace (avoid oxidation and slagging treatment), and refining and degassing in a holding furnace.

Due to the limited filtering capacity of the filter, too dirty aluminum alloy liquid will cause the post-filtered aluminum alloy liquid to be more dirty than the first-filtered aluminum alloy liquid.

The viscosity of the filtered aluminum alloy liquid is reduced, and the fluidity is increased by 10% ~ 15%.

Therefore, the filling capacity of the aluminum alloy melt can be improved by filtering.

Before filtering, the flow of aluminum alloy fluid is turbulent, and after filtering, it becomes laminar (the curvature of the ceramic foam filter is curved in the flow path), thereby reducing the volume of air and two types of slagging.

In the filtering process, the filtering mechanism filters from the sieve and the filter cake to the deep layer. The purity of the filtered aluminum alloy is getting higher and higher (not exceeding the maximum filtering capacity of the ceramic foam filter).

AdTech has a complete quality control system for ceramic foam filters, including technical standards, testing equipment and testing methods to achieve product quality control requirements.

After the aluminum alloy material is mixed with slag, the performance of the alloy deep-processed parts is destroyed, and the yield rate is reduced, which will cause a certain economic loss.

In production, the method of slag removal and filtration is required to eliminate slag inclusions as much as possible.

Slag inclusions in aluminum alloy castings are one of the main factors affecting the quality of deep-processed products.

The quality of the product directly affects its market share and economic benefits.

In order to survive and develop, it is necessary to increase the added value of products and carry out deep processing.
