Secondary Copper

Custom Engineered Solutions for Copper Shaft and Holding Furnace Applications

Saint-Gobain Performance Ceramics & Refractories’ Non-Ferrous metallurgy solutions deliver unparalleled corrosion, oxidation, and chemical resistance, improving furnace service life and performance under the harshest operating conditions. We are uniquely able to offer differentiated materials in custom formats that maximise your price to cost benefit.


Shaft Furnace


Shaft furnaces are used for melting copper cathodes and copper scrap. It consists of a vertical cylindrical chamber with burners located in the lower part of the furnace. These furnaces have operating temperatures of up to 1,200°C, which may increase in certain parts of the furnace.


Holding Furnace


Copper holding furnaces are necessary for the continuous casting process, which is used to solidify molten metal into a specific shape.


Refractory Linings


Saint-Gobain offers many types of refractory lining systems, including Cryston CU Max® , Twinfrax®, Cryston Max®, and Refrax ® and back up safety linings . Our engineered solutions offer a faster installation and turnaround solution with key benefits including superior life due to our patented Refractory products properties.


Can Saint-Gobain Performance Ceramics & Refractories products offer a longer service life?

Yes many customers who use our Cryston® CU MAX and backup lining solution experience longer campaigns and improved Copper output per lining.

Can Saint-Gobain Performance Ceramics & Refractories’ backup linings be reused?

Yes. Many customers opt to reuse the backup lining for the second and third-generation relines, significantly reducing construction time and disposal costs.

Does Saint-Gobain Performance Ceramics & Refractories offer a full refractory system including insulating materials?

Yes. A complete solution is provided, including refractory design, optimization, and the manufacture of silicon carbide bricks and custom shapes as required. A range of fully compatible insulating backup materials is also available.

Is onsite installation supervision available?

Yes. Installation supervision is available in most geographies - either via Saint-Gobain Performance Ceramics & Refractories or a trusted installation partner.

What are the key advantages of employing Saint-Gobain Performance Ceramics & Refractories’ refractory materials?

Saint-Gobain Performance Ceramics & Refractories takes a systemic approach to copper furnace applications, offering custom refractory solutions covering  every element of the furnace and its overall operation.

The patented composition of the Cryston® Cu Max hot face material ensures industry-leading service. At the same time, the innovative backup lining features a copper-resistant monolithic material specifically engineered for compatibility with the hot face.
