詳細介紹適用於吹砂式多工位殼型機的濕態覆膜砂性能；高強度低樹脂量覆膜砂的研製；濕態殼型覆膜砂的成形性指數與調濕工藝；翻鬥法制殼時的脫殼問題分析和解決辦法；覆膜砂脫殼性檢測方法；高鎳球鐵件殼型鑄造表面針孔原因分析與抗針孔覆膜砂的應用。 -
2. there are three measuring positions for temperature transducer : inner sand temperature of double disk cooler ; testing sand temperature near feeding hopper can reflect low temperature condition of old sand ; the temperature of double disk cooler top can reflect inner temperature change of double disk ; therefore, it can estimate temperature change according to this change
2溫度傳感器的測量位置有三處： 1雙盤冷卻器內部砂溫2進料口附近檢測砂溫，能夠反饋舊砂降溫情況3雙盤冷卻器頂部抽風口氣溫，反映雙盤內氣溫變化情況，由此氣溫可大致判斷雙盤內砂溫變化情況。 -
Shell capacity of film laminating sand is one important index for tipper hopper type shelling, shell core and technology of blowing method
覆膜砂的結殼性能不管對于採用翻鬥法製造殼型殼芯，還是採用吹射法製造殼芯的工藝都是一個重要的指標。
