本文通过测量内结晶器的变形,研究了内沟与石墨化膨胀及内结晶器变形的关系,指出了产生内沟的原因及其位置,为减少内沟提供了一定根据。
In this paper, by measuring the deformation of the inner mold, the relationship between the inner groove and the graphitization expansion and the deformation of the inner mold was studied. The reason and location of the inner groove were pointed out, which provided some evidences for reducing the inner groove.
