Abstract
A method of treating steel tundish. A first step involves subjecting the tundish to rapid cryogenic refrigeration until the tundish is micro-cracked and cryogenically imbrittled. A second step involves impacting the steel tundish with a force sufficient enough to facture and break apart the cryogenically micro-cracked and imbrittled steel tundish.
Claims
exact text as granted — not AI-modified1 . A method of treating steel tundish, comprising the steps of:
subjecting the tundish to rapid cryogenic refrigeration until the tundish is micro-cracked and cryogenically imbrittled; and impacting the steel tundish with a force sufficient enough to facture and break apart the cryogenically micro-cracked and imbrittled steel tundish.
2 . A method of treating steel tundish, comprising the steps of:
placing the tundish in a container; covering the container; introducing cryogenic freezing into the container and subjecting the tundish to rapid cryogenic refrigeration until the tundish is micro-cracked and cryogenically imbrittled; and impacting the steel tundish with a force sufficient enough to facture and break apart the cryogenically micro-cracked and imbrittled steel tundish.
3 . The method as defined in claim 2 , the container being a pit.
4 . The method as defined in claim 2 , the tundish being impacted by a steel ball being dropped from a height.
