Conclusions
The service of monoblock stoppers, controlling nozzles, and submerged nozzles with stream blowing of the metal with gas was studied. The desirability of use of a monoblock stopper with a hole in the lower portion and a thread in the upper for treatment of the metal with gas in the intermediate ladle was concluded.
The service of straight-through submerged nozzles under conditions of blowing was studied and means of increasing their life were noted.
