Beschreibung
Zusammenfassung:	PURPOSE: To obtain the carbon refractories for blast furnaces which have excellent thermal conductivity and slag resistance and facilitate production of large- sized blocks by kneading highly thermally conductive carbon raw materials, fine alumina powder, fine metal silicon powder and org. binder under specific conditions and subjecting the mixture to molding, burning, pulverizing and classifying. CONSTITUTION: The org. binder (coal tar pitch, etc.) is added to 100 pts. mixture composed of 70 to 90 pts. highly thermally conductive carbon raw materials contg. flaky graphite or/and artificial graphite of a particle diameter of
