Refractory for feeder and channel

Using electrocast zircon-mullite as main material, with scientific assorted grain size, high pressure formed and high temperature sintered, the products have excellent properties of bearing high temperature, corrosion resistance, and resistance to thermal shock, high strength and high refractoriness under load. They are especially suitable to flame zones of high- temperature furnaces.

Channel blocks made with silimanite, mullite, corundum refractories, by their high refractoriness, good thermal stability and resistance to corrosion of glass liquid and hence have the least contamination to glass liquid. The are the most common refractories used for the feeder machines and tube drawing machine in domestic and foreign glass industries.
