DEVICE AND METHOD FOR DIAGNOSING CRACKS IN A SOLIDIFIED SHELL IN A MOLD

摘要

The present invention relates to a device and method for diagnosing cracks in a solidified shell in a mold, which use a temperature variation of the solidified shell in the mold for the real-time determination of whether or not a longitudinal surface crack is generated during a continuous casting process. The device of the present invention comprises a temperature-sensing unit which includes a plurality of temperature-sensing parts arranged in an array at the mold, the temperature-sensing parts being divided into first and second groups according to an area in which cracks may occur, and a central processing unit which calculates the temperature variation between the first and second groups using the temperatures detected by the temperature-sensing unit, and diagnoses the generation of a crack in the solidified shell discharged from the mold using the calculated temperature variation.
