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.
The alumina ceramic foam 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
Alumina ceramic foam 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 the alumina ceramic foam 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 alumina ceramic foam filters 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.
