User manual for foam ceramic filter

Carborundum, Alumina, Zirconia, ceramic foam filter (Material: Al2O3/ SiC/ZrO2) for Metal / casting

Product Introduction

Foam ceramics filter with Germany imported polyurethane foam sponge as the carrier, filled with the silicon carbide,alumina cement,additives powder mix into a paste, then squeeze out slurry, and after drying, roasting sintered at high temperature, polyurethane thermal decomposition, the remaining coating what around the fiber pulp will leave the foam ceramics, it is the foam ceramic filter.

Foam ceramic filter have the three-dimensional structure of sponge can make the liquid metal reflect rectifying mechanical sieving filter cake filtration mechanism such as adsorption to effectively improve the purity of liquid metal, reduce rejection rate lower machining consumption so as to improve production efficiency to reduce the production cost

Aperture and Size selection of foam ceramic filter

When using rare earth foam ceramic filter, according to the number of inclusions in the quality needs of the casting and metal liquid to determine the filter pore size (inches product number of holes, PPI) filter aperture is divided into 10 PPI, 15 PPI and 20ppi, 25 PPI and 30 PPI specification products. Ductile iron castings for general use 10 PPI or 15 PPI specifications products, grey iron, copper casting.

General use 10 PPI, 15 PPI or 20 PPI specifications of products, aluminum alloy castings generally use 20 PPI, 25 PP or 30ppi specifications of the product. Rare earth foam ceramic filter thickness, the filter's strength is better, but its use cost is also higher. From the most appropriate intensity and filtration efficiency considerations, the general recommendation is as follows: 75-120mm, thickness 22 ~ 25mm, 25 ~ 30mm, 120 ~ >150mm, 25~30mm, 150mm, 30 ~ 40mm.

2.Size selection of rare earth foam ceramic filter

The size of the rare earth foam ceramic filter with the type and size of the casting two aspects to determine. Rare earth foam ceramic filter unit cross-sectional area of the maximum liquid metal filtration should generally be controlled within the scope of the following: nodular cast iron is equal to or less than 2kg / C square meters; gray cast iron, copper and aluminum alloy cast piece is less than or equal to 4kg/c square meters. The conventional rare earth foam ceramic filter filter size amount as shown in the following table
