BF with high aluminum brick according to resources conditions and products requires different, can used following several class raw materials: to containing water aluminum oxygen mineral (a water aluminum stone, and Sanshui aluminum stone,) for main composed of high aluminum bauxite; Silicon line stone family mineral (including blue spar, and Red pillar, and Silicon line stone,); artificial synthesis raw materials, as industrial alumina, and synthesis mullite, and electric melt corundum,. Bauxite in China is rich in resources and good quality habitats are mainly located in Shanxi, Henan, Hebei, Guizhou, Shandong and other places. high alumina refractory bricks by bauxite, aluminum is mainly a water stone (α-Al2O3 · H2O) and two mineral mixtures of kaolinite. Properties of high-alumina brick for blast furnace, fire resistance of high-alumina brick and refractory degree than clay bricks and half a silica brick of high refractoriness, 1750~1790℃, belonging to high quality refractories.
