Centrifugal Casting of Large Diameter and Thin Wall Tin Bronze Guide Sleeve and Its Process Improvement
摘要
Abstract
The large-diameter thin-walled guide sleeve,made of ZCuSn5Pb5Zn5,has high quality requirements,and was produced by a large roller centrifuge.According to the estimation of the maximum temperature of the mold,the judgment conditions of whether the mold needs to be water-cooled were given.When large diameter and short length sleeves on the equipment was casted,the method of filling up the gap can be used for the casting mold.For the large diameter and thin wall castings,it is important to prevent inclusions in the castings.The first piece was poured by slot pouring pipe,and the processed product was scrapped due to inclusion.After the process improvement,the double-row deluge pouring pipe was adopted,and the 8 products were compact in structure,free of inclusion defects and good in quality.关键词
