Abstract
A continuous casting nozzle for controllably casting an elongated ribbon has a discharge slot extending completely across an exterior surface of the nozzle in fluid communication with an internally disposed through flow passage. Refractory insert material compatible with the nozzle material, such as refractory cement, is filled into the longitudinal ends of the discharge slot to define the width of a centrally disposed discharge slot for the nozzle. The continuous groove with insert material allows for economy and flexibility in the nozzle manufacturing process and results in a nozzle having an adjustable discharge slot width less susceptible to stress cracks.
