Rath offers a wide range of refractory and insulating products for glass melting tanks, regenerative end-fired or cross-fired furnaces, recuperative furnaces, oxy-fuel or electro furnaces, as well as complete forehearth channels. We produce fireclay through 90% alumina brick, creep resistant 60% to 70% andalusite brick, and vacuum-formed/machine shapes.
KORRATH® grades are corundum, tabular alumina, mullite, and zirconia-based with high-density, high-purity, low porosity, and good-to-excellent thermal shock resistance.
KORRATH® is available in standard brick sizes (straights, arches, and wedges), as well as custom plates and shapes.
SUPRATH A40-T is an alumina, mullite-based product with very high strengths, excellent volume stability, and superior thermal spall resistance. Typical applications include air heaters, zinc furnace upper sidewalls, boilers, tunnel kilns, moderate temperature incinerators, aluminum furnace upper sidewalls, rotary kilns, brass furnaces, and glass furnaces.
ZIRRATH AZS28 is a fused alumina, zirconia, and silica (AZS) product designed for applications that require a high degree of corrosion, erosion, and thermal shock resistance. Typical applications include glass furnaces and forehearth superstructures.
ZIRRATH AZS20 is an alumina, zirconia, and silica (AZS) product with an enhanced matrix that provides superior alkali attack resistance. Typical applications include glass furnaces and forehearth superstructures.
TANKCOAT 45BZR is an alumina, zirconia, and silica (AZS) product that features excellent glass corrosion and erosion resistance. Typical applications include glass furnace paving, glass furnace overcoat, and day tank working linings.
ZIRRATH ZS65 is a high-density zircon refractory. ZIRRATH ZS65 exhibits excellent hot load deformation results. Typical applications include glass furnace paving, sub-paving, and buffer covers. Other applications include hearth, lower sidewalls, and belly-bands in severe service aluminum furnaces.
