Abstract
A cooling mold has first and second water cooling jackets provided inside the mold. A primary cooling water jetting mouth is located at a distance between 15 and 40 mm from the meniscus of the molten metal. A secondary cooling water jetting mouth is located at an interval of 20 to 45 mm between a contact point of a primary jet of cooling water and another contact point of a secondary jet of cooling water on an ingot. The primary and secondary cooling water jetting mouths are respectively set at an angle of 15 to 30 degrees and of 30 to 60 degrees relative to the ingot surface. The primary jet of cooling water from the primary mouth impinges on the molten metal cooled in the cooling mold at a distance from the meniscus to establish a transition boiling zone and a film boiling zone. The secondary jet of cooling water impinges on initial zones of the transition boiling zone and the film boiling zone to break-out a vapor film. A wiper is arranged downstream of the cooling mold to contact a circumferential surface of the ingot to wipe off the cooling water from the cooling mold and impinging on the surface of the ingot. A third cooling water jetting mouth is disposed downstream from the wiper.
