Description
Silica filtering scrim for foundry is made from silica fiber scrim or mock leno scrim with high temperature resistant surface coating. It used as filtration for molten metal, can improve quality of coasting. Silica filtering scrim has good properties of high temperature resistant, scour resistance, low gas evolution, easy to use and economic. It’s suitable for grey cast iron, nodular cast iron and small size cast steel casting filtration.
