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).
Claims14
A method of casting metal strip by introducing molten metal between a pair of chilled casting rolls to form a casting pool of molten metal supported above the nip, confining the pool at the ends of the nip by pool confining refractory end closures, and rotating the rolls so as to cast a solidified strip delivered downwardly from the nip;
- comprising preheating the pool end closures prior to casting by positioning adjacent the end closures elements susceptible to exposure to an electromagnetic field in such manner as to cause them to rise in temperature and exposing each of said elements to an electromagnetic field whereby to cause them to rise in temperature and so heat the pool end closures.
