Product Description

Alumina Carbon Ladle Upper Metering Refractory Nozzle
1. Good thermal shock resistance
2. Strong scouring-resistance
3. Good slag-resistance
4. Long life

Alumina Carbon Ladle Upper Metering Refractory Nozzle

Properties:

High refractoriness, good anti-clogging, superior resistance to thermal shock, erosion/corrosion etc. Especially the upper nozzles with ZrO2 Inserted feature high refractoriness and superior scouring resistance.

Description:

Stopper system is normally used in tundish for concasting of slab and bloom. Through adjusting the slot between
The stopper and the upper nozzle, the steel flowing rate could be controlled. During the casting, there will be some
Erosion on the stopper and upper nozzle. So the quality of the upper nozzle is very important to tundish life. Upper
Nozzles feature reliable performances and long service life. While working together with Mono block Stopper, the
Tundish casting sequences will be improved dramatically.
