【摘要】 <正> 一、前言泡沫陶瓷是净化合金熔体的一种极好的过滤材料,其过滤效果比之生产中常用的冲孔过滤片,金属网、钢丝棉及玻璃纤维过滤网要好。这主要是因为泡沫陶瓷有着独特的结构:连续纤细的陶瓷环状骨架围成无数相互连通大小不一的孔洞,具有了高孔隙更多还原

【Abstract】 The effects on in-ladle filtering process by ceramic filter had been tested on the La-Sr modified and N₂-F₁₂ refined aluminium alloy ZL102. Results of filtering were compared with that of orignal process in regard to the mechanical properties and fracture surface inclusions and pin hole evaluation as well as microstructures.更多还原
