1.Lower creep
2.To maintain the service life of the kiln
Such product selected superfine burned flint clay and high quality combined clay as main raw materials, and also selected materials which not easy to shrink and react with minerals at high temperature as additive . After high pressure shaping and high temperature firing , we can get this product.So the product has high strength,high density and low creep rate,and it can better applied to the hot blast furnace,glass furnace and chemical furnaces,etc.
