Al₂O₃-C slide gate plates

Al₂O₃(%)≥77.35～84.37; C(%)≥8.04～8.45
Cold Crushing Strength (Mpa): 150～157
Hot Modulus of Rupture (Mpa): 20～24

Application:

As the functional refractories for continuous casting, Al₂O₃-C slide gate plates are mainly used for large and medium ladle, in order to control liquid steel flow.

　　Al₂O₃-C slide gate plates use the bauxite and graphite powder as raw materials, phenolic resin as bonding agent, sintered at high temperatures under the reducing atmosphere.
