The effects of long nozzle

[2016-07-14]

When tapping molten steel from ladle to tundish, to prevent oxidization and spilling, we can install a long nozzle between ladle and tundish, the effects of long nozzle are as follow:

1.To prevent the molten steel from being reoxidized and improve the quality of steel; 2.Reduce the deposition of the oxydate of easily oxidized elements in inner wall of nozzle to prolong the service life of long nozzle; 3.Long nozzle can be used repeatedly, which can reduce the cost of refractory material.
