Abstract
A casting pool (30) of ferrous molten metal is supported on a pair of chilled generally horizontal casting rolls (22) forming a nip (27) between them. The casting rolls (22) rotate mutually opposite directions to produce a solidified metal strip (12) moving downwardly from the nip (27). The strip (12) passes along a transit path (10) which takes it away from the nip (27) in an unrestrained loop (29) disposed within a strip enclosure (38) within which the strip is confined through said transit path (10). The strip (12) moves downwardly from the nip (27) to form the unrestrained loop (29) passes between a pair of cooled non-contact heat absorbers (101) to which heat is radiated from the strip (12) whereby to extract from the strip heat generated by completion of solidification of metal therein after leaving the casting pool (30). Heat absorbers (101) are formed as opposite side walls of a cooling collar (100) defining an upper part of enclosure (38) and provided with cooling water ducts (102).
