The Calderys’ unique approach is the zoning. A specific range of products has been designed to meet the process conditions of each zone within direct reduction technologies. Contact us to know more about our specific range of products per zone.

Calderys has been providing refractory solutions for the industrial minerals for decades and is a reference supplier worldwide. Our team of experts selects the best suited products and services for your process requirements.

In pelletizer plant grates, different installation techniques are in balance depending on the need in speed, amount of repairs and degradation mechanism of the given area. Refractory selection is made to provide a reliable lining performance, so the customer gets visibility on its production and avoid unexpected halts caused by refractory failure.

Different installation techniques are available for the Alumina flash calciner and they depend on the need in speed, amount of repairs and degradation mechanism of the given area. Refractory selection is made to provide a reliable lining performance, so the customer gets visibility on its production and avoid unexpected halts caused by refractory failure.

An electric arc furnace (EAF) is a furnace that heats the metal by means of an electric arc. Maximizing its availability is a key challenge for steelmakers.

The steel ladle is a bucket-shaped vessel used to transport and pour out molten steel. Calderys solutions are customized depending on the size of the ladle and the operating requirements.

The holding furnace takes a key role in the modern foundry production environment. Containing large amounts of completely alloyed metal ready for transfer to casting stations, holding furnaces are typically the foundry's bottleneck requiring highly reliable refractory lining concepts that exhibit superior properties with respect to both corrosion resistance and thermal insulation. Calderys offers a wide product range for all sizes of holding furnaces for steel, iron, and non-ferrous alloys, including the lining of the commonly used channel inductor. Our main focus lies on the castable and dry vibrating technologies that both allow you to significantly reduce the energy needed per tonne of metal.

Pouring furnaces are found in various sizes and configurations, especially where automated moulding lines are used for large scale serial production. Calderys offers solutions for all sizes of pressurised and unpressurised pouring furnaces, including the lining of channel inductors or coreless inductors as well as completely coreless automated pouring furnaces. Our refractory materials are suitable for all alloys, including steel, iron, and non-ferrous alloys. Taking account for the ever increasing demand for sustainable production processes, we offer advanced insulating solutions for unheated pressurised pouring furnaces.

The tundish is a critical reactor within the steelmaking process, where flow dynamics, refractory design and insulation requirements play a key role in ensuring and improving steel cleanliness.

In some regions, Calderys can even pick up your old equipment, revamp in our premises and deliver to you hot, ready to receive metal. Contact us to learn more about the solutions available near you and to request a specific brochure on refractories for the aluminium dosing furnace.

Refractories installed in a calciner are facing severe conditions. A high thermal load in the burner area requires respective materials. The presence of alkalis, chlorine, and sulphur leads to the selection of corrosion-resistant products.

After a thorough analysis of your actual conditions (temperature, abrasion, chemical attacks, movements) we select from a wide range of potential solutions for the burner tip lining.

This furnace is used for melting aluminium scrap of all types (dirty scrap, borings, etc.) so the refractory solution depends a lot on the salt level of the liquid metal. Another important factor when deciding on your refractory lining is abrasion resistance of both the charge itself and of the cleaning tools.
