Study on the External Chill of Large Steel Castings
大型铸钢件外冷铁的研究
The traditional technique of internal Iron chill of steel castings hasn'tsatisfied with requirements of flaw detection quality of mill housings.
对于有探伤要求的轧机牌坊,采用传统的内冷铁工艺生产铸钢件的技术已不能满足质量要求。
The results show chill crystal zone of castings is formed when the solidifying interface captures a large amount and in a continuous way the high density floating crys-tals.
结果表明,铸件激冷晶区是在凝固界面对密度很大的游离晶连续、大量捕获时形成的。
