At Saint-Gobain, we always strive to deliver the perfect refractory solutions per customer specifications. In copper melting shaft furnaces, this means taking into consideration both thermal demands and unique geometries, but also the chemical aggressiveness of molten copper with varying chemical compositions. Our latest refractory solution for copper shaft furnaces falls under the Cryston® line; a tailormade range of refractory bricks for challenging hot face environments.
Cryston® CU is a copper-resistant refractory based on nitride or oxy-nitride bonded silicon carbide (SiC), It exceeds conventional nitride and clay-bonded SiC refractory solutions in secondary copper production owing to its superior chemical resistance and outstanding resistance to oxidation. Combined with superb all-round mechanical characteristics, Cryston® CU is the perfect refractory solution for hot face brickwork in shaft furnaces.
