The casting process advantages of ceramic sand

Ceramic sand, whose scientific name is ' fused ceramic sand for foundry ', is a calcined bauxite with aluminum oxide ( Al2O3 ) as the main component. It is made into foundry sand with different particle sizes by melting, blowing, screening and other processes.

The rapid popularization and application of ceramic sand benefits from its following casting process advantages : 

1, near spherical particles, smooth surface-binder consumption is small, less gas, good fluidity, good filling, good collapsibility after pouring ; 

2.Low thermal expansion rate-the thermal expansion rate of ceramic sand is comparable to that of zircon sand, which is 1 / 5 of silica sand and 1 / 2 of chromite sand. The expansion defects such as veining of castings can be basically eliminated by using ceramic sand to prepare mold and core sand. 

3, good crushing resistance-ceramic sand material density, strong crushing resistance, repeated use of low crushing rate, greatly improve the core sand recycling rate, reduce the waste sand emissions, is conducive to cost reduction and environmental protection ;

4.High refractoriness-Reducing sand sticking, reducing cleaning workload and improving the surface quality of castings. At the same time, it is especially suitable for the production of sand cores and steel castings with complex shapes and small cross-sectional areas. 

The bulk density is relatively small-the bulk density of Baozhu sand is about 2 g / cm3, which is less than 2.5-2.9 g / cm3 of chromite sand. 

6 、 The applicability of the binder and casting alloy process is good-the main component of the ceramic sand is Al2O3, which is a neutral material, acid and alkali binder system can be used, and adapt to a variety of casting alloys ; 

7 、 The particle size range of ceramic sand is wide-can be mixed according to the requirements of any combination to meet the different needs of customers ; 

8.High cost performance ratio-the price of ceramic sand is about 1 / 3.Although the unit price of the original sand is higher than that of silica sand, the comprehensive evaluation shows that under certain conditions, the use of ceramic sand has both certain economic benefits and significant environmental benefits, with high cost performance.
