Abstract
Thin, flaky graphite-containing refractories are obtained by refining and processing naturally occurring minerals and possess a specific size of the extent of the surface of a flaky layer and a specific thickness of a flake. Such flaky graphite-containing refractories exhibit high endurance and are effective as lining materials particularly for steel making furnaces.
Claims1
Graphite-containing refractories comprising a refractory aggregate and at least 3 wt % with respect of said aggregate of a thin, flaky graphite raw material wherein at least 30 % by weight of said thin, flaky graphite material has a size of D.gtoreq.0.105 mm and t.ltoreq.10 .mu.m, wherein D represents the size of the extent of the surface of a flaky layer and t represents the thickness of a flake, said flaky graphite being obtained by refining and processing a naturally occuring mineral.
