porous ceramic filter is a new type of filter with low density, high porosity and 

a three-dimensional network framework structure. It is widely used in the 

aluminum processing industry to filter molten aluminum to improve the quality of 

aluminum.

porous ceramic filter can effectively remove the non-metallic solid mixture in the aluminum and 

aluminum alloy melt, reduce the trapped gas, and provide laminar flow to make the 

filtered aluminum and aluminum alloy cleaner.

Clean metal can improve the quality of castings, reduce scrap, reduce inclusion 

defects, improve the quality of aluminum alloy and other non-ferrous alloy 

castings, and reduce the cost of castings. Its maximum use temperature is 

1200°C.

porous ceramic filter

porous ceramic filter has the advantages of high porosity, high mechanical 

strength, stable chemical performance, strong corrosion resistance, high 

adsorption rate, good filtering function, and good thermal shock resistance.

It is mainly used in the purification process for the production of non-ferrous 

alloys such as aluminum and aluminum alloys. It can also be used as a gas-solid, 

liquid-solid separation medium, catalyst carrier, burner, sound absorption and 

environmental protection.

A gasket is installed on the edge of theporous ceramic filter ;the gasket ensures 

the correct and tight position of the filter in the filter box.

There are different types of gaskets, such as ceramic fiber gaskets, etc., and 

porous ceramic filter without gaskets can also be provided.

These types of filters have been favored by customers from Europe, the Middle 

East and the United States for many years.

Product Features of porous ceramic filter High strength, no loose ceramic 

particles or powder

Three-dimensional connected mesh structure with high porosity.

The surface area of ​​slag collection is large, and the internal surface area of ​​

filtering is large,

Excellent thermal shock resistance.

Various sizes, shapes and apertures are available.

Particles larger than the pore size are captured on the top of the ceramic foam 

filter

The smaller particles will be trapped on the filter cake by the larger particles

The finer particles are trapped in the pores of the filter

Cast aluminum billets include smelting, purification, impurity removal, 

degassing, slag removal and casting processes, and homogenization processes.

The main process is:

(1) Ingredients: According to the specific alloy grade to be produced, calculate 

the addition amount of various alloy components, and reasonably match various raw 

materials.

(2) Smelting: The prepared raw materials are added to the smelting furnace to 

melt according to the process requirements, and the slag and gas in the melt are 

effectively removed by means of degassing and refining slag.

(3) Casting: Under certain casting process conditions, after the molten aluminum 

is cooled, it is cast into various specifications of round casting rods through 

the deep well casting system.
