Abstract

In recent decades

the prediction and control of shrinkage porosity and cavity defects in ingot were investigated. The distribution forms and formation mechanism of shrinkage porosity and cavity defects in steel ingot were expounded. Various criteria to predict the distribution of shrinkage porosity and cavity was summarized in detail

and the control measures were introduced. The development of the criterion of shrinkage porosity and cavity in ingot casting was prospected

and the issues of controlling shrinkage porosity and cavity defects were concluded.
