摘要：

Microprobe analysis of macroscopic inclusions in forging ingots of vacuum degassed steel revealed that they consisted of a matrix containing mainly Si, Mn, Al, and O//2 and occlusions of Al//2O//3. Their formation was traced to reaction between the liquid steel and the refractory lining of the dozzle of the ingot mold. Methods of avoiding this reaction are described.
