离心铸铁轧辊夹杂缺陷的形成和防止

Formation & Prevention of Inclusion Defects in Centrifugal Cast Iron Rolls

铸铁轧辊的夹杂缺陷是由于混在铁液中的各种夹杂物在铁液凝固前来不及浮出造成的，因此一切有助于减少夹杂来源、延长铁液从浇注到凝固的时间。

Inclusion defects of cast iron rolls are caused by various inclusions in the melt which cannot float on surface before solidification.All that reduce inclusion resource and prolong the time before solidification and speed inclusions floating out help to eliminate inclusion defects.
