低蠕变高铝砖 low creep high alumina brick

该系列产品以特级铝矾土熟料为主要原材料,辅以特殊添加剂,经高压成型、高温烧成,具有蓄热能力大、蠕变率小等特点。适用于中小型高炉配套热风炉。

This series of products is characterized by special grade aluminum bauxite clinker as the main raw material, supplemented by

special additives,high pressure forming and high temperature firing. It has the characteristics of large heat storage capacity and small creep rate. Applicable to small and medium sized blast furnace

supporting hot blast stove.
