Purging Plugs

Made from high-purity, high-density, high-strength corundum based materials and matrix-adjusted system(MAS), HT series of purging plugs, with the unique radiated through-slots structure, show the features of stable structure, high and adjustable gas-flow, high purging rate, good corrosion/erosion resistance and long service life etc.

Made from high-technology ceramic and high-performance castables and with the traditional through-slots as gas channel, HC series of purging plugs, as new generation of ceramic-clad purging plugs, not only succeed the advantages of HT series of purging plugs, but also show higher purging rate as result of adopting high-temperature ceramic as gas channel.
