Conclusions
A technology was developed for making steel casting nozzles for the continuous casting of steel with different versions of lateral input of metal into the crystallizer. In laboratory conditions we made nozzles 600–650 mm long.
The testing of the nozzles on continuous steel-casting plant at the Novo-Lipetsk Metallurgical Factory showed that they were highly resistant. It is possible to cast more than 260 tons of steel 3sp and 160 tons of steel 17G2SF through the nozzles, with metal input at an angle of 45° in the crystallizer; through nozzles with horizontal metal input in the crystallizer — 80 tons of steel 17G2SF; and through the nozzle with four apertures — 130 tons of such steel.
