Conclusions
A technology was devised for the manufacture of composite nozzles for casting boiling steel in continuous steel-casting units. The composite nozzle consists of porous chamotte nozzle (holder) and a high-alumina, magnesite or zircon liner (working part).
The composite nozzles with high-alumina liners showed greater durability than other liners during the tests.
