SEFPRO | Fused Cast Refractory Solutions

SEFPRO places particular emphasis on three fundamental properties of fused cast products which affect their use:. Oxidation level of the melted liquid: The oxidation level strongly influences compactness, blistering tendency, exudation, stoning and corrosion resistance.The optimal oxidation level depends on the melting process and proper control of the melting parameters within the furnace.

Refractory metals - Wikipedia

Refractory metals are a class of metals that are extraordinarily resistant to heat and wear.The expression is mostly used in the context of materials science, metallurgy and engineering.The definition of which elements belong to this group differs. The most common definition includes five elements: two of the fifth period (niobium and molybdenum) and three of the sixth period (tantalum
