铝锰青铜用砂型或铁模浇铸,只要采用底注法及有除渣的装置,并在适当的地方加冷铁或冒口,一般可以达到相当满意的成绩。我们为了提高质量,提高成品的合格率和实收率,会试用离心浇铸。以各种类型的阀杆作试验,采用垂直式离心铸造机,铸型用砂型制造。每箱安置直径15公厘的阀 Aluminum-manganese bronze cast with sand or iron mold, as long as the bottom of the note and slag removal device, and in the appropriate place to add cold iron or riser, generally can achieve quite satisfactory results. We in order to improve the quality and improve the finished product pass rate and real yield, will try centrifugal casting. With various types of stem for testing, the use of vertical centrifugal casting machine, the sand mold manufacturing. Each box to install 15 mm diameter valve
