Fig - Refractory Bricks being stacked in stock yard. Permeability is calculated by the following formula: Permeability = (Vol. of gas/air x thickness) ÷ (Area x Time of flow x Pressure difference) It is determined by forcing a known volume air or gas through a cube. Time of flow, pressure difference and dimensions of specimens are noted.
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.
