Optimized forms of the continuous casting mold and the immersion nozzle for casting steel slabs

摘要

Oscillating mould intended for continuous casting preferably of steel slabs with an a submerged melt outlet and use of casting powder incorporates a submerged melt outlet pipe (8) with a flow cross section (8.4) and an outlet cross section (8.3.1). It further incorporates freely movable narrow-side plates (1.3), and broad-side plates (1) which are plane in the direction of the mould length and are concave with a central symmetry in the direction of the mould with. The broad-side plates are additionally provided with a funnel section (5) corresponding to the cross section (8.1) of the melt outlet pipe at least in the melt level zone. This funnel section is at least partially reduced towards the mould outlet.
