The replacement is made of high quality alloy steel,upper nozzle using life over 50 hours              

collect nozzle is 8-10hours.if work together with tundish dry vibration mix,can improve the

tundish using life.which is used in continuous casting tundish.

Advantage:      

1.Lower-consumption on refractory material.                                                           

2.Simple-structure, light on weight. 

3.Reliable on working performance.

4.Improve the working efficiency.
