Abstract：
Traditional sand mold,centrifugal casting and metal mold casting were used in the trial production of high-lead bronze copper sleeve,and the castings could not meet the requirements of foreign customers.The copper sleeve produced by sand mold casting and centrifugal casting has serious component segregation.The copper sleeves were produced by common metal mold,there were some limitations.For castings with relatively thick wall thickness,the effect of common metal mold on preventing segregation was limited.A casting method for producing high-lead bronze sleeve by water-cooled metal mould is introduced.High quality castings are prepared by adding a water-cooling system outside the metal mold to improve the cooling rate and thereby reduce the composition segregation in the high lead bronze and producing high-quality casting.
