Large carbide dissolution in GCr15 continuously cast billet core
-
Zhiqiang Li
Abstract
In-situ tracking was used to evaluate the large carbide dissolution process in GCr15 continuously cast billet core. The time needed to dissolve the large carbides at different temperatures was investigated. As expected, the results showed that increased temperature can significantly shorten the complete dissolution time. Based on the spherical model, a new carbide surface area model to describe carbide size is presented in this paper; the parameters needed were evaluated from the experimental data. Appropriate homogenization cycles are also proposed.
