DAKEN Refractory Glazes for Continuous Casting-FCG

Home » Products » DAKEN Refractory Glazes for Continuous Casting-FCG

Daken FCG refractory glazes are specially designed for the carbon contained flow control refractories, when Daken FCG refractory glaze coating is applied to the surface of the carbon contained refractories and dried, it will first form a dense protective layer, as the temperature of kiln rises to the range of 700 to 900°C in firing process, the glaze coating starts to melt, transform into a continuous, smooth and pore-less glassy film. This refractory glaze layer could completely isolates the oxygen from the carbon and graphite inside of the refractories product body, which provides a long-lasting protection for the carbon contained refractories products at high temperatures.
