Refratechnik refractory

fire brickHow does refractory help in global economy?

In order to meet the globally increasing demand for cement, high output and energy-saving lining systems have been developed in the industrialized countries and introduced throughout the world. One of the primary result of these these developments is the pre-calciner kiln with a short rotary kiln section.

The use of alternative fuels has also taken on a new significance. Keeping pace with this technology requires suitable fire brick products and lining systems: the conditions inside the kiln are a determining factor of its service life.

Refractory concrete

refractory concreteIn constant efforts to intensify customer services and improve products, Refratechnik has developed innovative refractory concrete grades.

These low cement castable (LCC) are state of the art products in refractory technology and meet all the demands of processing and application behavior.

In order to obtain a long service life, even under the harshest conditions, it is most essential that the refractory concretes be installed correctly. Our supervisors are on hand to provide technical assistance and supervision during installation.

The concretes are produced in Gornal/Spain, and production is subject to the strict demands of DIN EN ISO 9001 and 14001.

The castable product range includes the following grades:

  • Regular Cement Castable (RCC)
  • Low Cement Castable (LCC)
