Sillimanite refractory bricks have the Refractoriness of 1770 ~ 1830 ℃, load softening starting point 1500 ~ 1650 ℃. Sillimanite bricks are widely used in feeder channels, feeder covers, burners, melting bottom paving of glass furnaces and other applications. Since sillimanite refractories have good high-temperature thermal stability, are resistant to corrosion of glass liquid, and have little pollution to glass liquid, they are mostly suitable for equipment such as forehearths, feeders, and pipe-drawing machines in the glass industry, which can significantly improve productivity. Sillimanite products include channel bricks, flow troughs, rotating tubes, spouts, bowls, mixing slurry, punches, barrels, fire-stop slag bricks, gate bricks, front arch bricks, rear arch bricks, bowl covers, and various varieties and specifications such as bricks, burning nozzle bricks, beams, and cover bricksAs a professional sillimanite bricks manufacturer, we have exported sillimanite refractory products to more than 30 countries.
