在铸型中放置冷铁可以控制传热,但要获得好的效果,使用技术和维护技术是很关键的,正确的管理和安放冷铁需要铸造技术人员根据铸件结构专门制订工艺。问:在我们的铸钢生产中,我们使用100~150 kg的冷铁控制凝固。能帮助我们更好地理解在大型铸型中放置冷铁的原则吗?答:有大量文献记录和论述了冷铁的重要性。不过,实践中仍然很难完全正确地使用冷铁,这是值得关注的。对于不熟悉的人来说,冷铁就是一块金属。
Placing chilled iron in the mold controls the heat transfer, but to get good results, the use of technology and maintenance techniques are critical. Proper management and placement of chilled iron requires the casting technician to tailor the process to the cast structure. Q: In our cast steel production, we use 100-150 kg of chilled iron to control the solidification. Can help us better understand the principle of placing chilled iron in large castings? A: There is a wealth of literature that documents and discusses the importance of chilled iron. However, it is still very difficult to use cold iron completely and correctly in practice, which is worth attention. For unfamiliar people, cold iron is a piece of metal.
