| Abstract: | The reason causing blowhohe defect on the top surface of A30 cylinder head was analysed, and preventing pertinence measures were set down. The blowhohe defect on the top surface of cylinder head casting can be solved effectively by the process using core sand with low gas evolution, preventing exhausting channel from being jammed during holistic soaking and spreading, and replacing casting mold by sand core to form core hole. |
