Unfired dense Al₂O₃-MgO bricks for steel ladle were prepared with corundum,spinel,alumina micro powder and magnesia as main raw materials,magnesium aluminate gel as binder.The properties of the brick were studied and compared with the existing steel ladle prefabricated brick.The results show that the mechanical pressed dense brick exhibits superior strength,apparent porosity,thermal shock resistance,erosion resistance and thermal expansion.It can be predicted that the application effect on the steel ladle will be better,which conforms to the concept of energy saving,environmental protection and high efficiency,and becoms one of the development trends of carbon-free refractories for steel ladle.
