Commonly used ladle castable varieties

1. Clay brick, clay brick and A12O3 content in ordinary during 30%-50%, low price. It is important for ladle backing layer and ladle bottom.
2. High alumina brick. The content of A12O3 brick during 50%-80%, it is important for the working layer of ladle.
3. Wax brick. The brick is characteristic of high content of SiO2. In general more than 80%, than the corrosion resistance and the mass of clay bricks, and without residue. Used in ladle wall and the bottom of the bag.
4. Zircon brick. The brick mainly for ladle slag line. The content of ZrO2 in ordinary brick during 60%-65%.
5. Magnesia carbon brick. The brick for ladle slag line, special apply to multiple ladle continuous casting sessions. The content of MgO in ordinary brick in 76% and, in the meantime the carbon content of 15%-20%. Its characteristic is to slag corrosion, corrosion resistance, good peeling property.
6. Alumina magnesia castable. The castable for ladle body, its characteristic is the utility in molten steel, casting material of MgO and A12O3 and Al ovate spinel, improved the lining slag resistance and thermal shock resistance.
7. Alumina magnesia carbon brick. This brick is on aluminum magnesium casting material basically developed ladle lining, has a long service life.
8. Unfired brick. Now the ladle for fire brick materials, almost all can be made compared to unburned brick. Its characteristic is compared with the producer process simple, low unit price. The brick itself has certain machine intensity and corrosion resistance, easy construction and masonry

If ladle for refining itself, you can also choose the MgO-Cr2O3-A12O3 series and MgO-CaO-C series refractory castable, important: magnesia chrome brick, magnesia chrome brick, aluminum dolomite brick. As in the brick of ladle lining containing graphite material, preferably coated with a layer of chemical synthetic coating at the surface, the dike in siopao, lining surface compound loose, affect the using life.
