TY-H fused cast alumina block comprises of a majority of β alumina crystals and a slight portion of α alumina crystals in compact structure. Moreover, the intersected texture of large β-alumina ensures great dimensional stability and great resistance against spalling. Its property of base saturation enables a higher resistance to alkali vapor, thus it has excellent thermal shock resistance and does not form molten droplets. It is the best material for molter crown, port crown,feeder channel,ect. TY-H Alumina Block Application --Widely used in port mouth ,breast wall and top crown of floating successive furnaces. --Superstructure where batch scattering. --Molter crown, port crown,feeder channel,ect.
