Refractory alloy and mineral wool production method

摘要

An alloy endowed with high strength at high temperature in an oxidising atmosphere comprises a matrix containing chromium reinforced with carbide precipitation. It includes carbides of at least one metal (M) chosen from titanium, zirconium and hafnium and may possibly also contain tantalum (M'). Independent claims are also included for: (a) an article made from this alloy for the hot production or transformation of glass; (b) a fibrillation plate for the fabrication of mineral wool; (c) the fabrication of the article; and (d) the fabrication of mineral wool by internal centrifugation.
