Ultra-high temperature polycrystalline alumina fiber board

  The products are fabricated by suck-press combined method using polycrystalline alumina fiber as main starting materials, adding packing materials and binders. Compared with calcined fiber products, the products are featured with better machinability, lower thermal conductivity, and volume weight. The FHB1800 fiberboard and special shaped products can long-term serve at 1750℃ and at 1800℃ of the maximum and have been used in many kilns to substitute imported products, saving energy and cutting cost.
