Abstract
A thin slab nozzle contains a central bore extending downstream along longitudinal axis Xfrom an inlet orifice at an upstream end. The central bore comprises an upstream bore portion with a height Ha, in communication with a converging bore portion of height He, in communication with a thin bore portion of height Hf ending at the upstream end of a divider, and first and second front ports separated from one another by the divider and coupled to the central bore portion at least partially at the converging bore portion. Xis a transverse axis, normal to X, along which the nozzle becomes thinner in a downstream portion. In a section of the thin slab nozzle along a symmetry plane Πdefined by Xand by X, the bore wall of the converging bore portion is curved at all points, and Hf/He≤1.
