冷冻铸造法在日本越来越受到重视。日本名古屋工业技术试验所已正式将能够简便地制造高级复杂铸件的冷冻铸造新工艺纳入研究课题。所谓冷冻铸造法就是在组成铸型的型砂颗粒中加入少量的水分和微量补助粘结剂(在理论上并不需要),利用液态氮或者其它极低温度的冷冻使铸型中的水分在-196℃的温度下急速冷却结冰,用冰来固结型砂的铸型制造方法。冷冻铸造法具有①浇铸后处
Frozen casting method in Japan more and more attention. Japan’s Nagoya Industrial Technology Testing Laboratory has formally included in the research project a new process for the production of high-level, complex castings by means of a freeze-casting process. The so-called frozen casting method is to form the mold sand particles to add a small amount of water and a trace amount of auxiliary binder (in theory do not need), the use of liquid nitrogen or other very low temperature freezing the mold in the water - 196 ° C rapidly cooled icing, with ice to consolidate sand mold manufacturing method.
