Abstract

A pouring nozzle is provided for use in a container for metal melts. The pouring nozzle has an inner wall surrounding a through-flow opening for metal melts and an outer housing. During operation of the pouring nozzle a pressure of at maximum 500 mbar exists between the inner wall and the outer housing.

Claims

exact text as granted — not AI-modified
1 .- 9 . (canceled) 
     
     
         10 . A pouring nozzle for use in a container for metal melts, the pouring nozzle comprising an inner wall surrounding a through-flow opening for metal melts and an outer housing, wherein during operation of the pouring nozzle a pressure of at maximum 500 mbar exists between the inner wall and the outer housing. 
     
     
         11 . The pouring nozzle according to  claim 10 , wherein the pressure is at maximum 400 mbar. 
     
     
         12 . The pouring nozzle according to  claim 10 , wherein the pressure at maximum 300 mbar. 
     
     
         13 . The pouring nozzle according to  claim 10 , wherein the pressure is 100 to 400 mbar. 
     
     
         14 . The pouring nozzle according to  claim 10 , wherein the pressure is 250 to 300 mbar. 
     
     
         15 . The pouring nozzle according to  claim 10 , further comprising a pump for generating the pressure. 
     
     
         16 . A pouring device having a container for metal melts, wherein the pouring nozzle according to  claim 10  is arranged in a wall of the container. 
     
     
         17 . A method of operating a pouring nozzle for a metallurgical vessel having an inner wall surrounding a through-flow opening for metal melts and an outer housing, the method comprising operating the pouring nozzle by generating a pressure of at maximum 500 mbar between the inner wall and the outer housing. 
     
     
         18 . The method according to  claim 17 , wherein the pressure is generated at a maximum 400 mbar. 
     
     
         19 . The method according to  claim 17 , wherein the pressure is generated at a maximum 300 mbar. 
     
     
         20 . The method according to  claim 17 , wherein the pressure is generated at 100 to 400 mbar. 
     
     
         21 . The method according to  claim 17 , wherein the pressure is generated at 250 to 300 mbar. 
     
     
         22 . The method according to  claim 17 , wherein the pressure is generated with help of a pump.
