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.
