Abstract
The abnormality is detected during a flow thereof through the mold. The detection is achieved by means of at least a pair of upper and lower temperature detecting elements, located along the flow of the casting metal. The abnormality is determined to exist when a temperature inversion, that is T.sub.U .ltoreq.T.sub.L, takes place. The symbols T.sub.U and T.sub.L denote the temperatures measured by the upper and lower temperature detecting elements, respectively, in which a relationship, that is T.sub.U >T.sub.L, stands under a normal casting operation.
