Ceramic Foundry Sand

      "Weiye" brand ceramic foundry sand is made from high quality bauxite by calcination, electrofusion, granulation,sieving and other processes.

Product characteristics:

1. The sand is spherical, with good fluidity, good filling performance and good air permeability.
2. Ceramic foundry sand are neutral materials, and both acid and alkali binders can be used.
3. Good recycling performance, cost-effective.
4. Smooth surface, compact structure, uniform coverage of the binder, the amount of addition reduced by 30% - 50%.
5. Its thermal expansion coefficient is small, the performance can be comparable with zircon sand, with it to prepare core sand, castings will not produce expansion defects.
6. High refractoriness, easy to collapse.
7. High thermal conductivity, good stability and no cracking.
