Application of Ceramic Filters for Casting
2022-01-11

The basic materials of ceramic filters for casting are silicon carbide, zirconia, and alumina.

Application of Ceramic Filters for Casting:

The ceramic foam filter has an excellent filtering effect on copper water or molten iron. It uses a three-dimensional structure to effectively remove oxidized inclusions and other non-metallic inclusions by blocking, capturing, and adsorbing. Whether it is gray iron, ductile iron, shaft, cylinder, or complex large and precision hardware parts after filtering, the product quality will get satisfactory results.

The basic material of the foundry ceramic filter is zirconia ZrO2. The heat-resistant temperature of zirconia filter mesh is higher than about 1760 ℃, and it has very high strength and excellent high-temperature impact force.
Cast steel parts are widely used where high strength and elongation requirements are required. Steel castings are therefore very sensitive to defects caused by impurities. The excellent characteristics of the zirconia ceramic foam filter can effectively remove impurities that cause product quality defects.
The ceramic filter for casting can make the molten steel fill the cavity more uniformly, and the molten metal has a high turbulent flow tendency during pouring. The laminar flow can fill the cavity better, thereby reducing the impact corrosion of the metal solution on the casting cavity and significantly reducing the scrap rate.
