DRY REFRACTORY COMPOSITIONS WITH REDUCED LEVELS OF RESPIRABLE CRYSTALLINE SILICA
A silica-based dry refractory composition ("DRC") comprising, by weight, about 95% to about 99.9% silica, and about 0.1 to about 5% binder, wherein the silica comprises about 40% to about 80% quartz and about 20% to about 60% fused silica, and the DRC has less than about 5% crystalline silica having a size less than 10µm. A method of forming a refractory lining is also provided.
Une composition réfractaire sèche à base de silice ("DRC") comprend, en poids, environ 95 % à environ 99,9 % de silice, et environ 0,1 à environ 5 % de liant, la silice comprenant d'environ 40 % à environ 80 % de quartz et d'environ 20 % à environ 60 % de silice fondue, et la DRC comprend moins d'environ 5 % de silice cristalline ayant une taille inférieure à 10 µm. L'invention concerne également un procédé de formation d'un revêtement réfractaire.
