It is widely used in dairy, beer, food, beverage, pharmaceutical and chemical industries. In iron and steel smelting role is particularly prominent.

The long nozzle can prevent the secondary oxidation of molten steel and improve the quality of steel.The oxidation products of easily oxidized elements in steel were deposited on the inner wall of the nozzle to prolong its service life.Long nozzle can be used many times to reduce the consumption of refractories.
An invasive nozzle is used to prevent secondary nitriding and spatter of molten steel.Adjust the flowing state and injection speed of molten steel.Preventing non-metallic inclusions of protective slag from being involved in molten steel plays an important role in promoting the floating of inclusions in molten steel.

The nozzle is the joint between the frame and the parts formed by the factory when casting the model.The inlet and outlet of a thermalized liquid flow.Molten steel flows into the mold cavity through the nozzle.

Long nozzle: when pouring molten steel from ladle to tundish, in order to prevent oxidation and splashing, a long nozzle is installed at the lower end of the sliding nozzle at the bottom of the ladle, one end is connected with the lower nozzle, and the other end is inserted into the molten steel of the tundish for sealing protection pouring.

Invasive nozzle: in continuous casting, an invasive nozzle is arranged between the tundish and the mold in order to improve the quality of the billet.
