摘要

CPR1000型主泵泵壳采用铁素体含量为12%

0%的奥氏体不锈钢铸造。介绍了泵壳铸件制造的关键工艺

采用自硬砂造型

选择底返式快速浇注并用氩气保护的浇注工艺。采用1包浇注

包孔直径为110mm（两个）。横浇道直径为140mm（两个）

内浇道直径为100mm（4个）

浇注时间为120

50s

金属液面上升速度为12

0mm/s

浇注温度为1 520

550℃

成功铸造出了主泵泵壳。

Abstract

CPR1000 primary pump shell was manufactured with austenite duplex stainless steel contained12%to 20%ferrite by sand casting.The self-hardening sand was adopted to fabricate sand mold

and bottom-back rapidly pouring with Ar protection was designed.Through using one steel ladle pouring with diameter of ladle of 2×φ110 mm and diameter of runner of 2×φ140 mm as well as diameter of ingates of 4×φ100 mm

the CPR1000 primary pump shell was produced successfully with lifting velocity of 12

0 mm/s at 1 520

550 ℃for 120

50 s.
