A new refractory solution to increase productivity
Calderys is an expert in specialty bricks, refractory monolithics and casting, with a comprehensive portfolio to support customers in many sectors. For aluminium customers – and secondary remelters
particularly – a new product is tackling a long-term problem of operating in harsh environments. We spoke to Sebastien Duguet, Aluminium Market Manager for Calderys,
who explains how ALKON® SOL CAST HT is helping customers save time after relining and repair work.
WHO ARE YOUR TARGET CUSTOMERS FOR ALKON® SOL CAST HT? ALKON® SOL CAST HT is ideal for harsh environments where the refractory operates in extremely hot temperatures – greater than 1200°C. Generally, the customer that ticks the box will be a secondary aluminium producer – those who re-melt aluminium scraps to make new products. Customers that are mainly melting very corrosive alloys with a high level of magnesium, with high melting rates, heavy charge and heavy skimming tools. Once the liquid aluminium has melted, the contact areas inside – the hearth, the ramps, the sill, the bath walls – face combination of flame impact & thermal shocks,

mechanical wear, and corundum growth, that is when aluminium alloys react with the refractories and destroy them. So, customers rely on a special product for protection, and ALKON® SOL CAST HT is pushing the limits the process operation can achieve.
