(Summary description)Green foundry is the development trend of foundry industry in the future. As a green molding material, ceramic foundry sand has been widely used in resin sand (furan resin, phenolic resin), sodium silicate sand (organic grease, CO2 hardening), precoated sand. Ceramic foundry sand is suitable for all kinds of metal castings, such as: carbon steel, alloy steel (high manganese steel, high chromium cast iron), cast iron, copper and so on.

Green foundry is the development trend of foundry industry in the future. As a green molding material, ceramic foundry sand has been widely used in resin sand (furan resin, phenolic resin), sodium silicate sand (organic grease, CO2 hardening), precoated sand. Ceramic foundry sand is suitable for all kinds of metal castings, such as: carbon steel, alloy steel (high manganese steel, high chromium cast iron), cast iron, copper and so on.
 
                             

Ceramic foundry sand is the ideal sand for precision casting industry and it has the following characteristics.
 
1. The coefficient of thermal expansion of ceramic foundry sand is relatively small, which is equivalent to that of zircon sand. It can be used in modelling, core-making, casting and so on, basically eliminating expansion defects, such as veining and other defects.

2. Ceramic foundry sand is spherical in shape, good in fluidity, easy to fill, good in permeability and collapsibility.

3. With smooth surface and compact structure, the ceramic foundry sand can be evenly covered by adhesive, whose addition amount is reduced by 30%-50%.
 
4. As a neutral material, both acid and alkali binders can be used, and it is suitable for various casting alloys.
 
5. Ceramic foundry sand is suitable for various recycling methods and has good recycling performance and high cost performance.
 
6. Ceramic foundry sand has high refractoriness and good stability, especially suitable for producing steel castings.
 
7. Ceramic foundry sand has a wide range of particle sizes, which can be mixed according to customer requirements
