摘要

在精密铸造中

可采用电熔白刚玉砂粉（α-Al2O3）替代锆英做型壳面层。电熔白刚玉粉面层浆料的粉液比为1:（3.1～3.3）

面层砂根据铸件表面要求不同可以采用白刚玉砂、棕刚玉砂、莫来砂

均可生产出合格铸件

降低了生产成本。同等条件下用1t锆英材料

如改用电熔刚玉只用0.8t

按目前锆英砂2.1万元/t计算可节约成本1.5万元/t。

Abstract

Face layer of mold shell was made with fused corundum instead of zircon sand.The slurry-solution ratio of fused corundum for the face layer adopts 1:（3.1～3.3）.Meanwhile

according to requirements of parts

qualified castings can be produced with using whiteα-Al2O3

brownα-Al2O3and mullite sand in face layer to reduce product cost.
