Cement kiln tertiary air duct prefabricated member
The invention relates to the field of refractory materials, in particular to a cement kiln tertiary air duct prefabricated member. The cement kiln tertiary air duct prefabricated member is prepared from, by weight, 20-50 parts of white corundum, 18-30 parts of mullite M, 15-40 parts of electric smelting magnesium aluminate spinel, 10-30 parts of electric smelting hercynite, 3-5 parts of zirconium carbonate, 3-5 parts of silicon carbide, 2-3 parts of silica powder, 2-8 parts of alumina micro powder, 0.1-1 part of sodium tripolyphosphate and 5-10 parts of an additional binding agent. The electric smelting magnesium aluminate spinel comprises 15-25 parts of 5-8 mm electric smelting magnesium aluminate spinel granules, 5-20 parts of 3-5 mm electric smelting magnesium aluminate spinel granules, 5-15 parts of 1-3 mm electric smelting magnesium aluminate spinel granules and 5-15 parts of 0-1 mm electric smelting magnesium aluminate spinel granules. The electric smelting hercynite comprises 10-20 parts of 5-8 mm electric smelting hercynite granules, 5-15 parts of 3-5 mm electric smelting hercynite granules, 5-10 parts of 1-3 mm electric smelting hercynite granules and 5-10 parts of 0-1 mm electric smelting hercynite granules. A preparation method of the prefabricated member comprises the steps of preparing a stirring material A, preparing a mixture B, preparing a sample tertiary air duct prefabricated member, preparing a first tertiary air duct prefabricated member, preparing a second tertiary air duct prefabricated member and preparing a final tertiary air duct prefabricated member. The cement kiln tertiary air duct prefabricated member is high in castable wear-resisting property, good in high temperature resistance and high in thermal shock resistance.
