Casting of metal |
摘要 |
Method for continuously casting metal strip of the kind in which molten metal is introduced into the nip between a pair of parallel casting rolls (16) via a metal delivery nozzle (19) disposed above the nip to create a casting pool (30) of molten metal supported on casting surfaces (16A) of the rolls immediately above the nip and the casting rolls (16) are rotated to deliver a solidified metal strip (20) downwardly from the nip. The casting surfaces (16A) are smooth so as to have an Arithmetic Mean Roughness Value (Ra) of less than 5 microns and the casting pool contains material to form on each of the casting surfaces a thin layer interposed between the casting surface and the casting pool during metal solidification a major proportion of which layer is liquid during the metal solidification and the liquid of the layer has a wetting angle of less than 40 DEG on the casting surface. This promotes wetting of the smooth casting surfaces and increases heat flux during metal solidification.
