CASTABLE REFRACTORY

摘要

PURPOSE: To provide a castable refractory excellent in the service life which is used for a foundry ladle, vacuum degassing treatment, etc. ;CONSTITUTION: The castable refractory consists essentially of 0.5-5.0wt.% fine calcined magnesia powder 0.1-5.0wt.% glass material and the balance alumina. Also it consists essentially of 0.5-5.0wt.% fine calcined magnesia powder, 0.1-5.0wt.% glass material, ≤60wt.% magnesia and/or spinel and the balance alumina. The castable refractory is excellent in slag permeability resistance, corrosion resistance and spalling resistance.;COPYRIGHT: (C)1993,JPO&Japio
