Agglomerate brick, for use in furnaces, is composed of aluminum oxide as a fine dust together with a bonding agent and a hardening accelerator

The agglomerate brick, for use in shaft or Corex or blast furnaces, is composed of 1-30 wt.% bonding agent, up to 10 wt.% of a setting and fixing accelerator and the remainder of Al2O3 in particles with a grain size of at most 3 mm and preferably as dust. The brick has a compression strength of at l...
