MANUFACTURE OF CONTINUOUS CASTING NOZZLE

摘要

METHOD OF MANUFACTURING NOZZLES FOR CONTINUOUS CASTING A method of manufacturing long or immersion type nozzles to be used for the continuous casting is provided, in which the refractory material containing flake graphite is kneaded by controlling its kneading force to prevent serious breakage of the graphite flakes. Thus the lowering of plastic deformability of the material may be prevented and the products of improved thermal shock resistance and highly stable quality can be obtained. As a result, the service life of the nozzles can be improved remarkably.
