Foundry methods for nodular iron castings with medium and small size 中小球墨鑄鐵件的鑄造工藝
Abstract : it was verified through experiment and measurement that there was growth phenomenon taking place with nodular iron castings after graphitizing annealing at low temperature . the emergence mechanism and reason of the “ annealing growth nature ” was dicussed , and its prevention measures was proposed 文摘:通過試驗和測試,證實了球鐵件經(jīng)低溫石墨化退火后存在的生長現(xiàn)象,并對這種“退火生長性”產(chǎn)生的機理及原因進行探討,提出了防止措施。
