Rongsheng blast furnace microporous carbon bricks not only have excellent conventional properties but also have excellent performance in use, including alkali resistance, thermal conductivity, iron molten corrosion resistance, oxidation resistance, and iron molten permeability resistance. At the same time, the air permeability is low, the average pore size is less than 1 μm and the pore volume percentage of pore size less than 1 μm is greater than 70%. Microporous carbon bricks for blast furnaces are mainly used in the hearth and bottom of blast furnaces. They are resistant to alkali corrosion and iron molten penetration. They can achieve the purpose of high efficiency, energy saving, and long life of iron-making blast furnaces.

Raw Material Composition of Microporous Carbon Bricks

Microporous carbon bricks are made of high-temperature (1500 ~ 2000℃) electric calcined anthracite as the main raw material, with appropriate amounts of natural graphite, aluminum oxide, pure silicon powder, silicon carbide and other materials added, and the binder is medium-temperature asphalt. Adding pure silicon or silicon carbide can effectively reduce the pore size, reduce the penetration of molten iron and slag, and improve the thermal conductivity and oxidation resistance of carbon blocks. Adding aluminum oxide can increase the carbon block’s resistance to alkali metal salt corrosion and molten iron corrosion. The production process of microporous carbon bricks is the same as that of ordinary carbon bricks.
