fdv porous ceramic filter
-
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.
