The development and function of long nozzle

 The invention of long nozzle started from the demand for the protection of molten steel pouring. Its use played a good role in preventing the secondary oxidation and slag entrapment of molten steel, and played an important role in the development of molten steel continuous casting. Tundish liquid steel pollution in different periods of continuous casting are almost related to the long nozzle, which has attracted the attention of more and more metallurgical workers.

In recent years, long nozzle has been continuously upgraded in terms of materials, structure and process operations. The new designed long nozzle structure realizes the immersion pouring, which effectively alleviates the serious entrapment and air suction during pouring. With the development of continuous casting technology, refractories are taking on more metallurgical tasks, and the metallurgical functions of the long nozzle are becoming more diversified, such as detection of slag under the ladle, formation of dispersed bubbles, and prevention of filling compound pollution. But the primary task of long nozzle is still protect the pouring of molten steel.
