Application Scope of Fused Ceramic Sand

Application of Fused Ceramic sand in large castings

At present, fused Ceramic sand is widely used in resin sand (furan resin, phenolic resin), sodium silicate sand (organic resin, CO2 hardening), and coated sand. Suitable for various metal castings: such as carbon steel, alloy steel (high manganese steel, high chromium cast iron), cast iron, cast copper, etc.


Application of Fused Ceramic sand in large complex castings

The use of Fused Ceramic sand to make diesel engine water kit maintains the characteristics of the original sand, overcomes the shortcomings of the original sand, such as large expansion coefficient, large amount of binder and large gas generation, reduces the amount of resin added, and improves the yield of the product.


Application of Fused Ceramic sand in large steel castings

The sand can also be mixed with silica sand. The proportion changes according to the size of the casting and the steel grade. It also achieves the effect of non-sticking sand and easy collapsing.


Application of Fused Ceramic sand in investment casting

Fused Ceramic sand has high fire resistance and can be used to sand the surface of investment casting of steel castings instead of zircon sand.


Application prospect of Fused Ceramic sand in auto parts

For a long time, the automotive industry has been the largest market of the foundry industry. In recent years, the development of China's automotive industry has continuously driven the foundry industry into a new period of development, and its rapid development has also led to the rapid expansion of the foundry market and given it broad prospects for development.

Application conclusion

Fused Ceramic sand, which is suitable for various casting methods. Such as V method, VRH, lost foam, investment molding, general sand mold (clay sand, sodium silicate + CO2 hardening), resin sand, etc. It is applicable to the production of castings with various binders and metal materials. It can not only greatly improve the quality of castings, but also is easy to clean sand, and the sand mixing process is simple and convenient (a small batch of sand is used locally for a single piece in a large steel casting plant, and a small amount of sand can be mixed manually). For most castings, the coating can be omitted, especially suitable for making castings with high quality requirements.

It is worth noting that in the use of sodium silicate CO2 hardening sand, the dried cores and moulds should not be dried in the kiln (if drying, the heating speed must be controlled). With the development of foundry industry and the requirements of social environmental protection, more and more manufacturers will use Fused Ceramic sand locally and completely. It has been known as green beads casting material, and has a good prospect of popularization and application.


Fused Ceramic sand effectively solves the problems of high casting cost and poor casting quality

Lost foam casting enterprises have been affected by many factors in recent years, resulting in the low qualified rate of finished castings. Among them, the characteristics of high production cost, high defective rate and low quality of castings have become the three mountains of lost foam casting enterprises in China. How to solve these problems cost performance of foundry products as soon as possible has become one of the most important tasks for domestic foundry enterprises. As we all know, the selection of molding sand in the casting process is a crucial link in the whole process. Once the sand is improperly selected, it will affect the overall situation. Therefore, EPC enterprises should make more efforts in the selection of molding sand.


Summary of application of Fused Ceramic sand

According to relevant data, at present, most domestic foundry enterprises have improved the selection of molding sand, abandoned the traditional low-cost silica sand, and adopted fused ceramic sand to improve the casting problem. This new type of sand is the product of the combination of school and enterprise, which integrates the advantages of high fire resistance, good fluidity and high air permeability. To a certain extent, it has solved the defects in the casting production, so it has been widely concerned by the international casting industry and has become the new favorite of lost foam casting. The three major problems of casting cost, defective rate and quality of lots of casting enterprises have been effectively alleviated.
