本文叙述了冷冻铸造法砂型的特性,並通过铸钢件、铸铁件的实际浇注试验,证实了在冷冻铸造工艺试验方面所取得的成果。本文认为:型砂水分控制在4％左右,铸型冷冻温度控制在-50℃～-80℃,就能满足冷冻铸造的需要。最后,还对冷冻铸造生产铸件成本进行了探讨。 This article describes the characteristics of the frozen casting sand, and through the casting of castings, castings of the actual casting test, confirmed the results of the freeze-casting process test results. This paper argues that: sand water control in about 4%, the mold temperature control in the -50 ℃ ~ -80 ℃, will be able to meet the needs of frozen casting. Finally, the cost of castings for frozen casting is also discussed.
