furnace refractory bricks for sizing nozzles for continuous casting machine Laddle furnace


Brief Account:
Given-diameter zirconic water outlet is made of zirconia and imported natural baddeleyite , formed by high tension and baked in high temperature when stablized by special technology. Different sizes and types of outlets are designed and made according to user's different steel-making conditions and requirements.
Specific Property:
It is refractory, well thermal- shock resistant, anti-eroding, anti-erosive, changeless diameter and lasting long.
Application:
In casting steel it is mainly used in successive-casting intermediary small square adobes, big square adobes, rectangle adobes and small board adobes.
