Title
(PT) artigo refratário que contém grafite e método para fabricar artigo refratário que contém grafite
Abstract
(PT)
trata-se de um artigo refratário que contém grafite que tem uma maior resistência â flexão e energia de fratura do que aqueles de artigos refratários convencionais, e um método para fabricar o artigo refratário. esse artigo refratário que contém grafite tem um teor de grafite que varia de 1% em massa a 80% em massa, e tem disposto no mesmo um feixe de fibras de carbono que tem um comprimento de 100 mm ou mais e que é obtido agrupando-se 1.000 a 300.000 filamentos de uma fibra de carbono que tem um diâmetro de fibra que varia de 1 µm/filamento a 45 µm/filamento.
