Fused Quartz Nozzle

Quartz Nozzle have Submerged Nozzle and Long Nozzle; 

From the function nozzle :1.Hanging Nozzle

                     2.Submerged nozzle 

                     3.Quick-exchange nozzle

Long Nozzle: Argon blowing Nozzle

           Ladle argon un-blowing nozzle; and nozzle big than 1500 mm extra large nozzle.


The quartz nozzle with good thermal shock stability, corrosion resistance, erosion resistance, and can

reduce the cost of continuous casting ; Can be custom make as per client’s requirement.

Application:

Used in the field of metallurgy, electronics, defense , scientific research , especially for the continuous casting of steel for steel making.

They are mainly used in the basic zones of small billet,big billet, rectangular billet.etc.


1) Service life depends on steel-making condition, refractory slide gate and different operation mode.

2) We can mark different material indifferent part and detailed index according to the drawings.

3) Delivery time depends on the drawings.If new mold are needed, an additive period may be necessary.
