Functions of Zirconia ceramic foam filter
1.Efficiently filter metal particles impurities such as slag and refractory fragments to the micron level to reduce the loss of tools during machining of castings
2.The molten metal filling is stable and the structure of the casting is uniform, thereby improving the mechanical properties such as surface hardness, tensile strength and fatigue resistance of the casting
3.The three-dimensional mesh structure has a good rectification effect on metal turbulence, and has a good control effect on non-metallic inclusions and secondary oxidation caused by turbulent erosion of the cavity.
4.Simplified gating system and improved cavity utilization
5.The surface of the casting is clean, reducing the machining allowance, shortening the cleaning time, and improving the delivery efficiency
