ABSTRACT:
Twin roll casting of metal strip by introducing molten metal between chilled casting rolls (16) to form casting pool supported on the rolls and confined by refractory end closures (56), and rotating the rolls (16) so as to cast a solidified strip delivered downwardly from the nip between the rolls (16). Prior to casting refractory end closures (56) are preheated by positioning adjacent their inner faces a pair of metal plates (130) and exposing those plates to electromagnetic fields to cause them to rise in temperature and so heat the closures (56). Plates (130) have hooked top flanges (131) for location on the refractory end closures (56).
