Ladle has a long nozzle effect. When molten steel is poured from ladle to tundish, in order to avoid oxidation and splashing, a long nozzle is installed at the lower end of the sliding nozzle at the bottom of ladle, one end is connected with the lower nozzle, and the other end is inserted into the molten steel of tundish for sealing protection and pouring. The function of the long nozzle is as follows:
(1) Prevent secondary oxidation of molten steel and improve the quality of steel
(2) Reduce the deposition of oxidation products of easily oxidized elements in steel on the inner wall of the water outlet and extend its service life
(3) The long water nozzle can be used multiple times to reduce the consumption of refractory materials

Features of long spout:
1. A variety of different blowing structures can be arbitrarily selected according to needs
2. Anti-oxidation coating can effectively prevent carbon bonded materials from being oxidized
3. Refractory fiber blanket to prevent heat loss during steel pouring
4. The standard aluminum carbon body material has excellent properties, does not burst, corrosion resistance
5. The high standard of mismaterial ensures that the slag line has excellent corrosion resistance
6. The standard magnesium material ensures that the slag line part has excellent corrosion resistance to Ca treated steel
7. The inner carbon-free material ensures the special requirements of ultra-low carbon steel, silicon steel and clean steel
The function of the long nozzle is:
Prevent the secondary oxidation of molten steel, improve the quality of steel, reduce the oxidation products of easily oxidized elements in steel deposited on the inner wall of the nozzle, extend its service life; The long nozzle can be used multiple times to reduce the consumption of refractory materials.
Long water outlet shall have the following properties:
Excellent thermal shock resistance; Good mechanical properties and vibration resistance; Good corrosion resistance to molten steel and slag; The side joint must have an air seal device.
Long keter is a professional refractory manufacturer, providing you with quality refractory products and the best service for a long time.
