1. The use of ceramic foundry sand (ceramsite) and roasted sand ratio process can save material costs by about 20% compared to the original chromite sand and clinker sand ratio process.
2. The sand core produced by this process has high strength and dense surface, the quality of the inner cavity of the casting has significantly improved, and the sand sticking defects in the inner cavity have been significantly reduced from 0.6% to below 0.2%.
