  • Ladle Shroud

    Ladle Shroud

    Ladle shroud also known as the protective sleeve, is mainly used between the ladle and the tundish. It is an important part of the connection between the ladle and the tundish. The lower part of the upper connecting ladle is connected with the water outlet of the sliding nozzle device, and the lower end extends into the tundish. It prevents the molten steel entering the tundish from the ladle from being re-oxidized and splashed; protects the molten steel from secondary oxidation during casting, improves the quality of the molten steel; reduces the deposition of oxide products in the steel on the inner wall of the nozzle, and extends the service life.

  • Tundish Stopper

    Tundish Stopper

    Tundish stopper is a refractory rod that is installed in the steel bucket to control the opening and closing of the nozzle and the flow of molten steel by lifting displacement, also known as pottery stopper. It is composed of rod core, sleeve brick and plug brick. The rod core is usually made of plain carbon steel round steel with a diameter of 30-60mm. The upper end is connected with the cross arm of the lifting mechanism by bolts, the lower end is connected with the plug brick by threads or pins, and the middle sleeve brick.Tundish stopper must be carefully built and used after baking and drying for more than 48 hours to avoid breakout accidents caused by refractory explosions.

    The integral stopper rod is installed in the tundish when in use. The flow rate of molten steel entering the mold can be adjusted by controlling the position of the stopper rod head to the tundish nozzle, and argon can also be blown to the tundish through the argon blowing hole to prevent the nozzle from being blocked.

  • Magnesia Carbon Brick

    Magnesia Carbon Brick

    Magnesia carbon bricks are made of high melting point alkaline oxide magnesium oxide (melting point 2800°C) and high melting point carbon materials that are difficult to be infiltrated by slag as raw materials, and various non-oxide additives are added. A non-burning composite refractory material combined with a carbon binder.
    The main raw material for the production of magnesia carbon bricks, the quality of magnesia has an extremely important influence on the performance of magnesia carbon bricks. The purity of magnesia has a significant impact on the slag resistance of magnesia carbon bricks. The higher the magnesium oxide content, the lower the relative impurities, the lower the degree of silicate phase separation, the higher the degree of direct bonding of periclase, and the higher resistance to slag penetration and slag melting loss. The impurities in magnesia mainly include calcium oxide, silicon dioxide, and iron oxide. If the content of impurities is high, especially boron oxide compounds, it will adversely affect the refractoriness and high temperature performance of magnesia.
