When Lucky Aluminium Karachi Ceramic Foam Filter filters liquid aluminum, the liquid aluminum flows through the tortuous holes of the ceramic filter plate, and the non-metallic impurities and oxide film (commonly known as slag) in the liquid aluminum are affected by the axial pressure, friction, and surface adsorption of the aluminum liquid. The combined action of force, etc., is retained on the inner surface of the hole of the ceramic filter plate and the crevice cavity, thereby separating the slag and the molten aluminum.
After a period of filtering, the slag remaining on the ceramic filter plate also participates in the adsorption of the slag, which can play a filtering role.
Since the performance of the slag adsorbed on the ceramic filter plate is exactly the same as the slag to be adsorbed in the aluminum liquid, its surface area ratio is much larger than that of the ceramic filter plate, and the surface activity is much greater than that of the ceramic filter plate, so the ability to adsorb and trap the slag in the aluminum liquid is far Much larger than the ceramic filter plate.
Because of this, the ceramic filter plate can filter out the fine slag that is many times smaller than its own hole.
In the filtering process, the slag adsorbed on the ceramic filter plate gradually grows up after adsorbing and intercepting the slag in the aluminum liquid.
Under the agitation and scouring of the liquid flow, the extremely low-strength slag may break or fall off the ceramic filter plate.
In the process of slag falling off, if the ceramic filter plate is thicker or has small holes, it may be intercepted or adsorbed again.
When Lucky Aluminium Karachi uses the new Ceramic Foam Filter, slightly larger inclusion particles in the aluminum melt may pass through the pores of the filter plate. These “large particles” inclusions are inherited in the cast-rolled billet and affect its internal quality.
When the filter plate is used for a period of time, some small impurity particles will be adsorbed at its pores. As the amount of filtration of the aluminum liquid does not gradually increase, the adsorbed particles in the pores of the filter plate continue to accumulate, so that the pores of the filter plate become smaller and the filtering effect is improved. .
But when the amount of impurities adsorbed by the filter plate is so large that it blocks the pores of the filter plate, the filtering effect begins to decrease, and the quality of the cast-rolled billet is correspondingly reduced.
It can be seen from the test pinholes that the two-stage filter plate can well remove the small particle inclusions in the aluminum melt, and has a better purification effect on the aluminum melt.
