MORAL CAST 180 AR RFT

  • An extremely high purity, low iron castable based on sintered alumina blended with low iron, high purity calcium aluminate cement.

  • Maximum Temperature Rating         18150C

    MORAL CAST 180 AR RFT develops a strong, rapid set with excellent strength development and volume stability throughout its entire temperature range. The castable performs very well in reducing and oxidising atmospheres and is relatively unaffected by carbon deposition.

    The comprehensive range of MORAL CAST dense castables covers the complete temperature spectrum up to 18150C. Four classes of product are offered; standard, abrasion resistant, gunning and extra-coarse aggregate. These products have been designed utilising different aggregates and cement binders to ensure they meet the requirements of most applications.

    Strict adherence to quality control measures has enabled each Thermal Ceramics Australia location to gain AS3902/IS09002 quality standard accreditation. All products are manufactured according to these tight standards, ensuring consistent high quality.
