Ceramic Foam Filter-PZr

Ceramic foam filter PZr is a kind of high adsorption ceramic filter plate. CFF foundry Filter adopts a three-dimensional network structure. It uses an organic foam as a carrier and penetrates into the thixotropic ZrO2 molten material slurry.

Ceramic foam filter adopts four correction center distance and automatic extrusion process. So the slurry is evenly applied to the foam frame of the carrier. After curing and drying, the foam filter was successfully fired at a high temperature of 1680 degrees. It is in the filtering box for filtering impurity in molten aluminum alloy. AdTech ceramic foam filter can meet the requirement of production in high- tech performance aluminum alloy.

Application of Ceramic Foam Filter-PZr

Ceramic foam filters can effectively remove and absorb large or small impurities in molten aluminum. It can improve surface quality, product performance, and microstructure effectiveness. The casting filter is mainly used in aviation, transportation, computer hard drive, PS baseboard for printing, canning materials, fan blades for turbojet engine, and other aluminum alloy precision casting.

AdTech alumina ceramic foam filters are available in all common sizes: 7″, 9″, 12″, 15″, 17″, 20″, and 23″. AdTech offers the whole range of porosities from PPI 20 up to PPI 60. It can also be customized according to customer needs. Ceramic foam filters are equipped with a gasket on the edges. The gasket assures the proper and tight position of the filter within the filter box. AdTech ceramic filter adopts sealing gasket in 3 different types, fiber paper material, fiber cotton material, expanding cotton material.

Zirconia Foam Ceramic Filter

The basic material of the zirconia foam ceramic filter is ZrO2. The heat resistance temperature of the zirconia filter is higher than 1760 ° C, and it has very high strength and excellent high-temperature impact.

Among various types of metal oxide ceramics, zirconia has the best high-temperature stability. And it is most suitable for ceramic coatings and high-temperature refractory products. The thermal conductivity of zirconia is the lowest among common ceramic materials, and the coefficient of thermal expansion is relatively close to that of metal materials. The special crystal structure makes it an important electronic material. Good mechanical properties and thermophysical properties make it a reinforced phase with excellent performance in metal matrix composites. Among various metal oxide ceramics, the use of zirconia ceramics is second only to alumina ceramics. Zirconia ceramics can obtain high strength and toughness through phase transformation toughening. Its flexural strength can reach more than 1500MPa, and the fracture toughness KIC can reach more than 15MPa • m1 / 2. Zirconia ceramic is equivalent to the strength and toughness of steel, so it is known as “ceramic steel”.

Molten Metal Filter

Ceramic Foam Filter Manufacturer

Cast steel parts are widely used in areas requiring high strength and elongation. Therefore, steel castings are very sensitive to defects caused by impurities. The excellent characteristics of the zirconia foam ceramic filter can effectively remove the impurities that ultimately lead to product quality defects. The impurities are mainly composed of non-metallic particles, slag, and refractory fragments. Filter-PZr can improve the surface quality and mechanical properties of castings, and reduce the rate of scrap.

The foam ceramic filter can make the molten metal fill the cavity more evenly. The molten metal has a higher tendency to turbulence during pouring. The liquid aluminum is through the three-dimensional pore structure of the zirconia foam ceramic filter, and finally converted into a very stable layer flow. Laminar flow has a better filling of the cavity, which reduces the impact corrosion of the molten metal on the casting cavity. If you are interested in our products, please feel free to contact us.
