System for introducing fluid to the cooling chamber of a rotating mould

摘要

The device comprises a rotatable mold (41) surrounded by an annular cooling chamber (42). An annular box (47) non-rotatably surrounds the outer wall (43) of the annular chamber. Two annular nozzles (50,51), integral with the box (47) each open into a passage (57,58) provided between the outer wall (43) and at least one non-rotatable wall. The fluid from the nozzles, after passing through the passage, into the chamber (42) through openings (44,45) preceded by the annular inlet zone (46). The invention also relates to a method of introducing a fluid into the annular cooling chamber of a rotary mold continuous casting of metals or alloys such as steels.
