Abstract
A tundish carriage for a double-strand continuous caster has a carriage frame displaceable on rails straddling a pair of parallel-wall or funnel-shaped continuous casting billet molds. The frame is of trapezoidal configuration with one relatively long beam and one relatively short beam connected by transverse beams at vertices provided with bolsters riding on the rails and with units for raising and lowering the trough for receiving the molten metal. The casting tubes extend downwardly from the trough and can be individually aligned with the respective molds without affecting the position of the other casting tube, utilizing an adjusting device at each bolster connecting a transverse beam with the longer of the longitudinal beams.
Claims6
A tundish carriage for a double-strand continuous caster having a pair of parallel rails straddling at least two continuous casting molds, said tundish carriage comprising:
- a carriage frame having longitudinal beams extending in a direction of displacement of said carriage along said rails and of different lengths, said longitudinal beams being asymmetrical with respect to a longitudinal axis of said carriage, and transverse beams interconnecting ends of said longitudinal beams at respective vertices to form a trapezoid with said longitudinal beams, wherein said transverse beams intersect angles of 30° to 60° with the longer of the longitudinal beams;
- respective bolsters at said vertices supporting said frame movably on said rails;
- a distributor trough on said frame for receiving molten metal and having a pair of casting tubes each arranged to register with one of said molds;
- and
- adjustment drives on the bolsters at the longer of said longitudinal beams for aligning one of said casting tubes in a respective one of said molds for one of said strands without altering a position of the other casting tube in the other mold for the other of said strands and vice versa.
