Abstract

In this paper

the mold design and the casting defects and corresponding resolving method of large-size aluminum alloy cylinder made by low-pressure casting are studied analyzed.It is shown that the casting microstructure is fine and the mechanical property meets the product requirement （σb≥294 MPa

δ≥5%

HB≥100） under the condition of 0.03～0.04 MPa filling pressure and 20～25 s filling time.
