ceramic foam filter for foundry molten metal filtration

Paglalarawan ng produkto
Silicon carbide ceramic foam filters are mainly designed to improve the quality of iron castings. The filter can effectively remove non-metallic inclusions including slag and dross from the molten metal stream.Additionally, they aid in reducing turbulence in the gating system.SIC ceramic foam filter's outstanding thermal shock resistance and high strength properties were developed for superior performance in extreme iron or aluminum and copper based alloy foundry applications.
