Aluminium foundries ceramic filter is a very economical and effective filter that can filter out non-metallic solid inclusions in aluminum and aluminum alloy melts. The ceramic foam filter plate adopts a three-dimensional network structure and connected pores of organic foam sponge as a carrier, which invades the special ceramic slurry with thixotropy, and adopts a […]

According to the molten Al filtration method, the molten Al is passed through a refractory ceramic foam filter to remove inclusions. Larger inclusion particles can be removed from the molten Al. However, it is difficult to remove small inclusion particles of 100 μm or smaller that account for most of the inclusions. In particular, it […]

Today’s aluminum industry requires strict metal quality standards to prevent parts failure in key components of automobiles, airplanes, and machinery. Filtration is the last online metal treatment performed before molten aluminum casting. To control the flow rate and reduce the level of inclusions entering the filter system, many other upstream processing stages are required, all […]

Ceramic foam filter is a particularly useful filter in the filtration of molten metal. Ceramic foam filter manufacturing process is simple, immers the polyurethane foam in the ceramic slurry, and fires the polyurethane foam. It can make porous, hard, self-sustaining ceramic foam filter products. Ceramic Foam Filter Manufacturing Process The flexible foam material is impregnated […]

Alumina CFF filtration is widely used in molten aluminum purification, ceramic foam filter is the most cost-effective filtration media. Alumina CFF Filtration 1. It can effectively eradicate large inclusions in molten aluminum. 2. It can remove small inclusions of a few micrometers in size that are incapable of conventional processes in molten aluminum. At the […]

The technology of removing non-metallic inclusions in the molten aluminum alloy, adopting the furnace flux treatment, and the technology of molten alu foam ceramic filter filtration outside the furnace has long become an important method for the purification of molten aluminum. Reflected in the alloying, purification, and refinement processing technology of the smelting process. The […]

The molten aluminum ceramic filter plate can effectively remove the large inclusions in the molten aluminum, and absorb the fine inclusion particles of micrometer size, improve the surface quality, improve the product performance, improve the effect of the microstructure, and increase the yield. It is widely used in the production of aluminum profile, aluminum foil, […]

Alumina foam ceramic filter plate produced by our company can effectively remove the fineness of aluminum water to reach the inclusion of micron grade, make aluminum water into stable laminar flow, and facilitate filling. It has a unique mullite corundum structure, good mechanical strength, and chemical stability, superior aluminum water scouring performance, and strict control […]

The foam ceramic filtration mechanism is generally described as diffusion interception and inertial collision interception or screening, sedimentation and deep bed filtration. The State Key Laboratory of Tsinghua University established a three-dimensional physical model and a two-phase flow model for the filtration mechanism of foam ceramics, and carried out simulation calculations, which is very helpful […]

With the development of science and technology, the requirements for aluminum and its alloy materials are getting higher and higher, and the traditional refining and degassing process cannot remove the tiny non-metallic inclusions in the aluminum melt. Therefore, many people have studied the purification methods, which can be divided into adsorption purification, physical purification and […]
