摘要
气孔为YC4112Q气缸盖的主要缺陷。通过正确选用芯砂 ,加强砂芯的排气 ,严格控制浇注温度、速度等工艺措施 ,使气孔缺陷得到有效控制 ,气孔废品率在 1%以下。
The main defect of type YC4112Q cylinder head is blowhole. We adopt measures such as selection of core sand, strengthening exhaust property of sand core, control of pouring temperature and speed to prevent blowhole. Meanwhile, reject ratio containing the blowhole is controlled within 1%.
