Ceramic Welding is basically a proven method for hot repairs of industrial furnaces under operating temperatures. A mixture of ceramic and metallic particles is projected with oxygen onto the hot refractory ceramic surface and melts on impact both the projected powder, as well as the surface, thus creating a bond, equivalent to metallic welding.
DUN caters to the growing application demand for refractories in the country emerging out of growth in the ferrous, non-ferrous, cement, petrochemicals and chemical industries.
“Shotcrete” is a wet-method for the application of special monolithic refractory materials.
Premixed, pumpable refractory castables are conveyed to the place of application with special high pressure pumps (approx. 250 bar) over distances until 80 m and more.
