Abstract
Method of inhibiting cracking of steel strip in continuous casting of thin strip with the steps of: assembling a pair of counter-rotating casting rolls each with circumferential casting surfaces positioned laterally to form a nip therebetween to cast metal strip downwardly from the nip where each casting roll has lateral coolant passages positioned circumferentially spaced inwardly adjacent the casting surface of the roll, providing a source of coolant to be delivered to a temperature regulator regulating the temperature of the coolant delivered to the coolant passages to between 85° F. and 110° F., assembling a metal delivery system above the casting rolls to deliver molten metal forming a casting pool supported on the casting surfaces of the casting rolls above the nip, and counter-rotating the casting rolls such that the casting surfaces of the casting rolls each travel inwardly toward the nip to produce a cast strip downwardly from the nip.
