CALDERYS Expertise in Reheat furnaces

For decades, Calderys has been working on developing innovative projects in monolithic refractory technology for reheating and heat treating furnaces of different sizes and capacities. All our offerings are based on energy saving solutions that improve the performance of the customer's equipment. We have sustained a long-lasting working relationship with the reheat industry – end users and OEM - in all types of furnaces: walking beam, walking hearth, pusher furnaces, and also rotary hearth, annealing and other thermal treatment furnaces.

It has become a necessity to supplement the reheat furnace industry and the rolling mills with a fully integrated refractory partnership which supplies materials, technology and installation services. Our advantageous solutions for reheat furnaces are based on our wide range of products and support from our marketing, research, drawing office, and sales teams.

Products & Applications

Our comprehensive range for rolling mill, reheat, and treatment furnaces is composed of alumina based products. It includes dense and insulating castables, self-flowing castables, dry gunning and shotcreting materials, ramming, casting and gunning of plastic mixes, dry vibrating mixes, and prefabricated shapes.

Our innovation process is based on a world class R&D team, coupled with very specialized construction and design offices for designing customized solutions in anticipation of future needs. We have recently developed very efficient and innovative solutions which improve the availability of the furnace and thus reduce considerably the shutdown time during the installation. One of the best examples would be our QD (quick dry) product range, which allows to reduce the dry-out time by yp to a 50%. We have also developed a precast solution, CALDE™ BLOCK, which is very sustainable for the following reasons:

  • No shuttering
  • Quick installation
  • Faster heating and less susceptibility to explosions
  • No need for machinery

Calderys most used products for batch and continuous furnaces:

  • CALDE™ CAST LX 58
  • CALDE™ CAST M28 HR
  • CALDE™ PLAST SUPERAL X-AB
  • CALDE™ PLAST SUPERAL AB
  • CALDE™ GUN M 60

Continuous Furnaces

We offer customized solutions based on a complete range of products that are adapted to the reheating process. The hearth high valuable castables have been specifically developed to achieve a long campaign and out of the necessity to avoid any defect that could damage the stocks. Skids and posts are unique to the pusher and walking beam furnaces. The right insulation contributes greatly to energy savings and steel quality avoiding black marks. We provide solutions in either cast in situ or precast pieces.
Our high performance range of insulating products allows Calderys to replace, advantageously, the previously used ceramic fiber materials.
