    nozzle Cylindrical Shape Graphite Refractory Bricks , Refractory Bricks Used In Blast Furnace

    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.
