Fused Cast High Zirconia Block TY Z95


The series of TY-Z are fused cast high zirconia refractories. They are made of artificial synthesis of high purity raw materials through special casting process. The crystalline texture is consisting of baddeleyite. So the characteristics of these products are excellent corrosion resistance and very low blister and stoning potential. These advantages can prevent liquid glass from pollution effectively. TY-Z can be used in a wide range of glass furnace, especially high quality and special glass furnaces such as TV glass, Borosilicate glass, Alumina silicate glass, Halogen lighting glass, Opal glass and Fiber glass. TY-Z are mainly consisting of TY-Z88-WS and TY-Z95-WS, and used in sidewall, throat cover, throat support, electrode block, dam block parts.
