ABSTRACT:
In a continuous casting method, a melt surface condition within a mold is monitored for melt surface abnormalities such as boiling, lack of powder, and a condition of slag beard formation by using image sensors. Also, a condition of Deckel formation is detected by using a load sensor through a sensor rod. Based on the monitored conditions, a casting speed, a flow rate of gas blown into a pouring nozzle, a flow rate of a melt poured into the mold, scatter of powder, and the like, are controlled to prevent the occurrence of the melt surface abnormalities, as well as removing a slag beard by a hitting oscillator and removing Deckels by the sensor rod.
