    摘要： Invention relates to a submerged entry nozzle (21) for the thin slab casting comprising a divider (14) having a geometry of the ogival type, continuous contours and an angle θ at the vertex comprised between 30° and 60°. The divider in its lower portion is narrowing symmetrically with its sides (15,15') towards the median vertical axis (13).

    摘要： A submerged nozzle (1) feeding by gravity with a molten metal or alloy (2) from a container (3) a slab (4) that is under formation in a mould (5) with cooling walls, comprises a form of a vertical tube (6) connected to the overhanging container (3) and terminates at the bottom with a flat diffuser (8) having two outlet ports (9,9') having rectangular cross-section and with an ogivally shaped central divider baffle (14) having a symmetrical contour without corners and adapted to define two passage channels (16,16') for the stream which correspond to said two outlet holes (9,9'). The cross-section (10) for the passage of the fluid at the highest point of the diffuser is narrower than the passage section (11) of the tube (6) according to a ratio 0,6-0,8. In addition the inner side walls (12,12') of the diffuser which are directed towards the narrow sides of the thin mould diverge symmetrically downwards from the median vertical axis (13). Further geometric and functional parameters to be fulfilled by the nozzle are mentioned.

    摘要： A production line for hot steel strips, being fed from two casting lines ( a, b ) for thin slabs of thickness ≤ 100 mm, only one of which ( a ) is aligned with a finishing rolling mill (g), comprises also two pairs of rotatable heating furnaces with mandrel (A1, A2; B1, B2), each respectively on either line, with an intermediate bypass section ( d ) between the furnaces of the first pair (A1, A2) to allow the endless rolling in a finishing rolling mill ( g ) located downstream. The furnaces (B1, B2) of the second pair of furnaces on the line ( b ) can be transferred along a path ( k ) from said line to the rolling line and vice versa for producing single strips. Furthermore an induction furnace ( f ) is provided upstream of the finishing rolling mill ( g ). Also the corresponding production process is described.
