Injection molded refractory compositions or unfired refractory MgO-based.

摘要

REFERS TO THE MASSES INNVENCION INJECTIONS OR FIRE RESISTANT Moldings unfired FIRE RESISTANT CONTAINING as the main component MAGNESITA SINTERED AND / OR DOLOMITA SINTERED, 0.5 to 5% BY WEIGHT OF bentonite, 1 to 5% BY WEIGHT OF SULFATE aLUMINUM AND 0.5 to 5% by weight compound alkaline. THE MASSES OR MOLDINGS of the invention is characterized as containing alkaline COMPOUND AS MGO. "KAUSTER" and / or hydroxide MGNESICO. MASSES AND MOLDINGS of the invention have the advantage that NOT OCCUR IN THEM MIGRATION OF BINDER AND NEITHER IS OBSERVED OR CRACKS DETACHMENTS by vaporizing.
