The porous ceramic foam filter uses polyurethane foam as a carrier, immerses it in a coating made of ceramic powder, binder, sintering aid, suspending agent, etc., and then extrudes the excess coating to uniform the ceramic coating ground applied to the carrier. The skeleton becomes a green body, and the green body is dried and […]

How to choose the correct ceramic foam filter? There are many impurities and the casting quality is average. A ceramic foam filter with a larger mesh can be used, and a glass cloth coarse filter is added in front of the filter. At this time, semi-continuous casting is important for coarse filtration using glass cloth. […]

In order to remove the alkali metal elements (ie Na, Ca, K, Li), the use of a chlorine-containing reactive flux gas is a recognized method for processing molten aluminum. Under equilibrium conditions, the chlorides of each of these elements are produced as reaction products. Except for LiCl, all these halide salts are pure species and […]

Al2O3 ceramic foam filter is just developed as a new type molten aluminium filter to decrease casting flaw in recent years. Alumina ceramic foam filter has the characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity. In industrial applications, filter materials are often chosen according to cost as well as their processing and […]

Gas porosity may occur if hydrogen is introduced into the molten metal when it is poured into the mould. Hydrogen can be drawn in through moisture or water vapour in the atmosphere. Aluminium degassing system is used to solve this problem and it is carried out as an important part of the aluminium casting process. […]

The foam ceramic filter manufacturer immerses the foam material so that it covers the mesh and basically fills the voids therein. The impregnated material is then compressed to discharge about 80% of the slurry, and the balance is evenly distributed throughout the foam material, preferably, so that some pores are blocked in a uniformly distributed […]

The ceramic filter factory produces foam ceramic filters for filtration solid impurities contained in molten aluminum. By passing the solid-laden aluminum liquid through a porous filter medium that does not pass the solids, the entrained solids are removed from the liquid. Molten aluminum usually contains entrained solids, which are harmful to the final cast metal […]

The ceramic foam filtering system is used to filter and purify non-metallic impurities in molten aluminum, which is very important to ensure the quality of aluminum products. Molten metal usually contains impurities in the form of inclusions, which are not removed during the refining process. In order to obtain advanced metal raw materials for thin […]

The filtration of molten aluminum can prevent the oxide film from entering the surface of the molten metal, but the temperature drop of the molten aluminum filter medium itself can cause blockage caused by the solidification of the molten metal. A molten aluminum filter medium made of a porous ceramic material and formed into a […]

The ceramic foam filter has the characteristics of large filtering area, good thermal shock stability, high chemical stability, good metal corrosion resistance and high filtering efficiency. Therefore, ceramic foam filters are used as high-efficiency filters for molten metal filtration and purification technology. This device has attracted people’s attention. In fact, there are many types of […]
