The inner and outer nozzles of the bottle are connected to the sliding valve system. A nozzle is installed on the inside of the sliding valve which is inside the bottle, which is called the internal nozzle of the bottle. Also, the outer part of the sliding valve also has a nozzle, which is called the outer nozzle of Patil.
The internal and external nozzles of the pot are responsible for guiding and passing the melt from the pot to the tank.
The difference between the internal and external nozzle of Patil
The difference between the internal nozzle of the bottle and the external nozzle is that a metal frame is also installed on the outer surface of the external nozzle of the bottle, which is the part of the sliding valve that is located outside the bottle, but the internal nozzle does not have such a metal shell.
The set well block and split ring are installed under the tandish container of Saba Steel Complex, cow head nozzles, the melt comes out from the two holes at the bottom of these nozzles and slabs are produced in the casting line. Well block and split ring are used for precise placement and installation of these cow head nozzles under the tandish container.
In EBT electric arc furnaces for steel production, the taphole discharge chamber is placed vertically on the furnace floor. When the discharge valve is closed, this chamber is filled with special refractory sand, which prevents the penetration of melt into the chamber. After finishing loading the furnace, an electric arc is created and the melting process begins.
