Rath now offers a new product that is ideally suited for achieving greater energy efficiency and saving costs. Altra® 1500C is an advanced development of the reliable polycrystalline wool of the Altra brand.
This new, non-classified polycrystalline high- temperature wool has been optimized for applications up to 1,400oC and is available as bulk fiber, blanket, and module blocks. Altra 1500C is suitable for a wide range of industries, from ceramics and petrochemicals to steel and metals. In recent months, Altra 1500C has already been successfully used by a number of the international refractory manufacturer’s customers.
For more than three decades, Rath has been a leading manufacturer of high-temperature insulation products such as wool, blankets, modules, and vacuum-formed parts. In use, temperatures of up to 1,650o C can be insulated.
The all-rounder of the proven Altra series is the new, non-classified polycrystalline high-temperature wool Altra 1500C, which offers numerous advantages in addition to maximum cost-effectiveness: maximum service life and highly efficient thermal insulation (up to 1,400oC) to save costs. The lightweight and strong Altra 1500C also stands for easy handling and installation; for example, the blankets are highly flexible for folding serpentine modules. Another advantage is the optimal compatibility: Altra 1500C fits with the entire Altra series family, a coordinated range of grades that provides efficient solutions for specific requirements.
“Altra 1500C is an innovative development from the Rath research department and opens up new perspectives and opportunities for our customers, especially when it comes to saving energy and costs,” said ChristopherKluthe, senior R&D Manager, Rath. “Due to the targeted combination of physical properties, high-temperature wool is particularlyenergy-efficientand,incombinationwithcommonrefractorymaterialssuchasbricks andconcretes,istheidealcomplementforacompleterefractorylining.”
Altra 1500C is suitable for numerous industries, from ceramics and petrochemicals to steel and metal, and particularly for applications with rapidly alternating heating and cooling cycles. To meet customer-specific requirements, Altra 1500C is available in a range of densities and dimensions.
Furthermore, the blankets can be individually processed into modules to customer requirements in terms of dimensions and density.
The use of non-classified high–temperature insulation wools (HTIW) is becoming increasingly important. While fibers with low biopersistence serve as non-classified alternatives in some processes, they are limited in their thermal and chemical resistance. “Polycrystalline fibers are also non-classified due to their unique microstructure and high fiber diameter, but their performance often far exceeds the requirements of the processes, while the investment costs are higher compared to other HTIWs,” Kluthe said. “Altra 1500C has been specifically tailored to offer all the advantages of polycrystalline fibers while being more economical in terms of investment costs.”
In the steel and metal industry, the new polycrystalline high-temperature insulation wool Altra 1500C has already been successfully used by several German and Austrian companies, for example, as linings in the roof, wall and door areas of bogie hearth forging furnaces, chamber forging furnaces, rolling mill furnaces, walking beam furnaces, and rotary hearth furnaces.
“The results were excellent; the product met all our expectations,” said Kluthe.
The Altra series consists of the Altra 1500C and other proved grades that have been on the market for many years and offer solutions for a wide range of requirements, including chemical resistance and maximum temperatures (1,650°C).
