Aluminium Foundries Ceramic Foam Filters for Metal Casting

Aluminium Foundries Ceramic Foam Filters use high-quality, high-purity materials, unique formula, and advanced environmental protection technology. The three-dimensional network structure is uniform, high strength, stable texture, no slag, high temperature resistance, and strong thermal shock resistance.

Aluminum alloy is easy to breathe and oxidize during the casting process. Therefore, there are gases and various non-metallic inclusions in the melt to varying degrees, causing defects such as loose ingots, pores, and inclusions. Significantly reduce the mechanical properties, processing properties, fatigue resistance, corrosion resistance, and anodic oxidation properties of aluminum, and even lead to product waste.

In addition, due to the influence of raw and auxiliary materials, the solution may contain some other metals that are harmful to the solution. For example, alkali metals and alkaline earth metals such as sodium and calcium, and some alkali metals, have an adverse effect on the properties of most aluminum alloys. For example, sodium not only causes the “sodium brittleness” of sodium-containing aluminum-magnesium alloys, but also reduces the fluidity of the solution. It affects the casting properties of the alloy.

Aluminium Foundries Ceramic Foam Filters have excellent performance, suitable for cleaning and filtering high-temperature aluminum and aluminum alloy solutions. It can filter non-metallic slag and slag as small as micrometers, making the surface of castings smoother, reducing processing losses, and filtering can make the aluminum liquid and cavity more uniform when pouring Molten metal has a higher tendency to turbulence, which is finally transformed into a very stable laminar flow through the turbulence of the three-dimensional pore structure, which can better fill the cavity, thereby reducing the metal solution pair. The impact corrosion of the casting cavity significantly reduces the rejection rate, reduces production costs, and improves labor productivity.

Foundry Foam Ceramic Filter is relatively simple and has strong performance. On the one hand, the products made from it have higher compressive strength and higher volume stability under high temperature conditions. It is dense and resistant to erosion and penetration. It has good resistance to quenching and high temperature environment, and can also resist chemical corrosion of chemical slag or solution.
