Definitions
- the thin mould is capable of containing a reliable, i.e. sufficiently thick, submerged nozzle, with its large copper plates having such a profile in the horizontal plane, around the meniscus level, to exactly match the profile of the submerged nozzle in the said horizontal plane, thereby keeping in every point of the middle region a constant distance between the submerged nozzle and the walls.
