Everything starts with refractory technology –

    today and tomorrow.

    How did refractory technology arise?
    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.
    What is refractory 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, castables, 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.
    What does refractory technology mean for 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.
