发明名称 METHOD AND APPARATUS FOR CONTROLLING TEMPERATURE OF THIN CAST STRIP
摘要 An apparatus and method for continuously casting thin steel strip includes a pair of counter-rotatable casting rolls having a nip there between capable of delivering cast strip downwardly from the nip, a metal delivery system capable of forming a casting pool supported on casting surfaces of the casting rolls above the nip with side dams adjacent the ends of the nip to confine the casting pool, and a hot rolling mill having work rolls with work surfaces forming a gap between them through which hot strip delivered from the casting rolls is rolled, the work rolls having work surfaces relating to the desired strip profile across the work rolls. Misting jets may be in intervals along the path of the cast strip exiting from the hot rolling mill to form a cooling zone, the misting jets capable of directing toward surfaces of the cast strip a mixture of gas and water having a ratio of gas over water between 9 and 90 to cool the cast strip at more than 1.6° C. per liter of water used.
