Fields of application

  • Industrial furnace industry: for the manufacture and maintenance of industrial furnaces, including metal melting furnaces.

  • Metallurgy: In metallurgy and foundries to protect furnaces and vessels during metal melting.

  • Glass production: In furnaces and kiln processes in glass production.

  • Energy: In thermal power plants and fuel burning plants.

  • Petrochemical industry: For various processes and equipment in refineries and chemical plants.

  • Steel: for furnaces for melting and refining steel.

  • Food industry: In ovens and baking equipment such as bakeries and pizza ovens.

  • Ceramic industry: In ceramic kilns for the production of ceramic products.

  • Automotive: For furnaces in hardening and refining of steel components.

  • Pharmaceutical industry: In facilities for the production of pharmaceutical substances and pharmaceutical products.

  • Cement industry: In rotary kilns for cement production.

  • Construction: for protecting buildings and structures from high temperatures, for example in quarries.

  • Paper industry: In furnaces and equipment for paper production.

  • Water management: in waste incineration and water purification plants.

  • Textile industry: In furnaces for dyeing and processing textile materials.

Production methods

  • Pressing: This method involves pressing materials to the desired shape and density. This can be the production of bricks, tiles or refractory boards.

  • Extrusion: extrusion is a process in which a material is extruded through a nozzle, producing tubes, profiles or plates of refractory materials.

  • Sintering: This method involves mixing powdered raw materials with a binder, followed by forming or casting, and then firing, which produces a solid structure.

  • Hand moulding: in some cases, refractory linings are created by hand, where the materials are moulded into the desired shape.

  • Cladding boards: the production of refractory cladding boards that are used to line surfaces such as ovens and fireplaces.

  • Compaction: this method involves compressing powdered raw materials into the desired shape with high pressure, creating refractory plates and materials.

  • Moulding by casting: casting a melt of refractory material into a mould to create more complex shapes or specific components.

Dry tocretation

Dry torrefaction is a specific method of applying refractories. Torrefaction is used to apply refractories to existing surfaces such as furnaces, tunnel structures, pipes, walls, etc.

It is a process in which a dry refractory material (often a mixture of raw material and binder) is sprayed or injected onto a surface at high pressure. This creates a refractory lining or layer. The production of refractories, as mentioned in the previous list, involves the production of the actual materials (bricks, slabs, granules, etc.) for various applications.

Dry torrefaction and the production of refractories are therefore two different stages in the process of protection against high temperatures and wear in industrial and construction applications.
