About Calderys

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.

Calderys is committed to providing complete refractory solutions for the electric arc furnace (EAF). Our complete refractory and services offering is tailored to specific EAF processes, utilizing our global and local manufacturing footprint, and dedicated technical support.

Our multi layer product designs are created to provide best possible thermal insulation to conserve energy, and to reduce the deformation effects on the steel shell structure.

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.

Calderys is the world's leading provider of refractory solutions for your aluminium foundry twin chamber furnace. Our monolithic refractory range fits particularly to the complex lining design of these furnaces. Calderys solutions allow excellent metal quality and very low energy consumption.

Calderys is world's leading provider of refractory solutions for the dosing furnace of your aluminium foundry. Our monolithic refractory range fits perfectly to the complex lining design of these furnaces. Our solutions allow excellent metal quality and also very low energy consumption. Calderys will adapt its refractory solution to your aluminium alloys, furnace geometry and thermal insulation requirements.

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.

These types of moving hearth furnaces tend to be used for variable size and geometry stocks. Our systems offer fast, user-friendly installation, good lining performance and overall energy cost savings. A very performing range of insulating products allows us to replace advantageously the ceramic fiber materials.

Bogie furnaces are of two types: Annealing with max temperature of 1150°C and Forging with max temperature of 1350°C. We can propose diverse solutions depending on your needs; we have selected some of our best sellers for this application.
