SEFPRO is the only supplier of refractory solutions specifically to the glass industries to apply a specification to AZS block colour. The process integrates an innovative non-destructive control method in its standard specifications by measuring the colour of Fused cast AZS refractories. The block colour assesses the state of oxidation, with insufficient oxidation generating in exudation and blistering, and at the opposite excessive oxidation making the block more porous and reducing its corrosion resistance.
This unique AZS colour specification ensures consistent quality and guarantees optimum corrosion resistance, resulting in higher glass quality for glassmakers.
