Melting furnaces are used to melt scrap or recycled aluminium, requiring a high heat input since the roof temperature can exceed 1,100°C.

Cast Refrax

Silicon nitride bonded silicon carbide

Cast Refrax silicon-nitride-bonded silicon carbide refractory is chemically inert to most materials. Its extreme hardness provides outstanding erosion resistance. The manufacturing methods allow complex geometrical shapes to be produced. It is ideal for use in high wear applications like launders and degassing rotors.

Benefits
Properties

Life spans much longer than alternative materials (e.g. graphite, refractory metals, refractory cements)
Dimensional stability over the lifetime of the component
Compatible with complex part geometries
