针对该产品体积大、壁薄、结构复杂的实际,采用垂直分型组芯造型,选择浇注时间为11.6 s、内浇道截流面积为1 800 mm2、浇注温度为720±10℃,采用芯头抽气装置、分型面开设出气槽等措施,防止了铸造缺陷的产生,提高了铸件质量。通过先淬火后检验校正再时效处理的热处理工艺和防变形工装,解决了热处理过程中的变形问题。 In view of the fact that the product is bulky, thin wall and complicated in structure, the core of the vertical parting core is adopted. The pouring time is 11.6 s, the runoff intercepting area is 1 800 mm2, the pouring temperature is 720 ± 10 ℃, Suction device, parting surface to open the gas tank and other measures to prevent the casting defects, improve the casting quality. Through the first quenched after the test remediation test heat treatment and anti-deformation tooling to solve the deformation of the heat treatment process.
