球墨鑄鐵是近年來鑄鐵發展中的一種新產品。由於其性能不容易掌握,故在生產與應用中還存在著問題。中國科學院金屬研究所為了解决生產中存在的問題及進一步改進此種鑄鐵的性能,於1952年八月與撫順礦務局簽訂了共同研究球墨鑄鐵加工的合同,决定進行探討球墨鑄鐵之可塑性及加工後之性能。由於雙方的密切合作,由於工作人員發揮了高度積極性,在金相檢驗、材料試驗及壓延、鍛造實驗工作中,證實了球墨鑄鐵的可塑性。十月下旬用電爐均熱的方法,進行了壓延與鍛造實驗,因為充分掌握了温度和時間,
Ductile iron is a new product in the development of cast iron in recent years. Due to its performance is not easy to grasp, so there are still problems in the production and application. Institute of Metal Research Chinese Academy of Sciences in order to solve the problems in production and to further improve the performance of such cast iron, in August 1952 and Fushun Mining Bureau signed a joint study of ductile iron processing contract, decided to explore ductile iron plasticity and processing After the performance. Due to the close cooperation between the two parties, due to the high enthusiasm of the staff, the ductility of ductile iron has been confirmed in metallographic examination, material testing and rolling and forging experiments. In late October with electric furnace soaking method, the rolling and forging experiments, as fully mastered the temperature and time,
