Method and apparatus for setting precise nozzle/belt and nozzle/edge dam block gaps.

摘要

Method and apparatus are described for precisely aligning the nozzle (14) of a tundish and feed tube supplying molten metal to a continuous caster to maintain desired clearances between the nozzle (14) and the belts and edge dams of the caster. A pair of guide pins (66) are mounted on sideplate extensions (26,28) of the caster and mating roller pairs (126,127) are mounted on the nozzle assembly. The nozzle is advanced toward the caster so that the roller pairs engage the guide pins. Both guide pins (66) are remotely adjustable in the vertical direction by hydraulic cylinders (50,88) acting through eccentrics. This moves the nozzle (14) vertically. The guide pin on the inboard side of the caster is similarly horizontally adjustable. The nozzle roller pair which engage the inboard guide pin are flanged so that the nozzle moves horizontally with the inboard guide pin.
