Zirconia Ceramic Foam Filter for Cast Steel

The basic material of zirconia ceramic foam filter for cast steel is zirconia ZrO2. The heat-resistant temperature of the zirconia mesh filter 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 foam ceramic filters can effectively remove impurities that cause product quality defects.

The zirconia foam ceramic filter can make the molten steel fill the cavity more evenly, and the molten metal has a high tendency to turbulent flow during pouring. Laminar flow. 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.

• Significant filtering effect on all steel grades, including carbon steel, stainless steel, cobalt-based nickel-based superalloys, etc.
• Made of pure zirconia material, the temperature can reach 1760 ℃, and it is not sensitive to the change of casting temperature of different steel grades.
• Excellent raw materials and advanced production technology ensure that the filter has a stable dimensional tolerance.

Non-metallic inclusions in castings are the main cause of casting defects, they affect the surface finish, mechanical and processing properties of castings and lead to increased rejection rate. The foam ceramic filter product is to remove inclusions and reduce turbulence to achieve fast and stable molten metal filling flow rate, and thus improve the quality of castings.
