Refractory technology

Past, present, and future.

From discovery to industrialization
Discovery and command of fire was an important evolutionary step for mankind. Fire not only stands for warmth and new ways to prepare food. The use of fire also had implications for the social and cultural development of human beings. New tools could be produced by melting, firing, and shaping various materials. High-temperature processes have been known for more than 4000 years. With the start of industrialization in the 18th century, different refractory processes and methods as well as their effects were investigated scientifically, and the findings were applied on a large scale.
A basic technology today
Refractory means that a material can be used at temperatures from about 600 °C up to about 1700 °C. Using alumina and magnesite-rich raw materials and minerals, bricks, mixes, and shaped components are developed, which are matched precisely to the respective materials, temperatures, and processes. Thanks to this basic technology, modern industrial furnaces in the cement, steel, aluminium, non-ferrous metals, glass, and chemical industries worldwide are fitted with highly specialized refractory linings.

Refractory is the future
Superlative tall buildings, artificial islands, tunnels under the sea – all over the world, architects, engineers, and investors are implementing bold ideas and spectacular projects.
New technologies make this possible. But also the structures of the 21st century are inconceivable without appropriate raw materials, without the use of fire and water, and without knowhow about reactions and bonds.

Industrial furnaces are the starting point for all cement, steel, ceramic, and glass structures, and every aluminium, gold, and ceramic product. Therefore, refractory products will continue to be essential for all industrial furnaces worldwide.

Wherever our world is headed for:
Everything starts with refractory products.
