1.Production of ceramic foam filter
Ceramic Foam filters are just developed as a new type molten metal filter to decrease casting flaw in recent years. With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance, Ceramic Foam filter is designed for filtering impurities from molten Iron & Alloy, nodular cast iron castings, grey iron castings and malleable castings, Bronze casting, etc.
2. Functions of ceramic foam filter
1). Thermal and chemical stability in high temperature,avoiding the chemical reaction with the filtered molten metal;
2). High porosity and good mechanical strength in high temperature due to its pure ceramic composite;
3). Low head loss,easy operation,energy-saving;
4). Making metal liquid flowing at stable speed and avoiding the sputtering and backset,thus increasing the surface quality of the cast part,preventing the pore disfigurement and finally lower down the unqualified rate;
5). Various sizes,shapes,apertures are available for kinds of foundry technique.
