Casting Apparatus And Method for Reducing bias flow

摘要

The present invention is a process for confirming whether or not an inclusion of at least one of a gas injection hole and a head portion formed on a stopper is attached and confirming whether a drift has occurred in a molten steel in a mold and a process for attaching an inclusion to the molten steel And increasing the supply amount of the inert gas supplied to the stopper when it is determined that the drift has occurred, it is possible to effectively reduce the occurrence of drift by checking whether the inclusion is attached to the stopper.;
