摘要
本文研究了负压度对消失模铸造的铸型强度、金属液充填能力、铸件表面质量的影响．结果表明，高的负压度会提高干砂铸型的强度和金属液的充填能力，在高负压度条件下，涂料高的透气性会导致铸件产生结疤缺陷。
Abstract: The effect on mold strength、fillability of iron melt and surface blemish of casting under variable vacuum was studied．The result show that the mold strength and fillability should increase, that high permeability of coating should result in forming scab on casting under high vacuum．
