Carbon bricks: The demand for blast furnace carbon bricks remains stable, while cathode carbon bricks for electrolytic aluminum are rapidly used

Keywords: anti-corrosion carbon bricks


      The environmental protection requirements of China's steel industry continue to rise, especially since the introduction of the dual carbon target, the industry's environmental protection requirements have been further clarified. The main ones eliminated in the steel industry are small blast furnaces, while those replaced and newly built are generally large blast furnaces. Large blast furnaces have a high demand for blast furnace carbon bricks and high quality requirements. In the future, the demand for blast furnace carbon bricks in the industry will continue to rise. With stable profit expectations for the carbon brick business and the dual carbon background, the transformation of electrolytic cells will drive the demand for cathode carbon bricks.

      The carbon dioxide emissions from the electrolytic aluminum industry account for about 5% of the total carbon emissions in society, making it one of the higher carbon emitting varieties in the non-ferrous metal field. Traditional graphite cathode electrolytic cell masonry often uses non graphitized and semi graphitized materials, which have poor conductivity and high energy consumption.

      The graphitized cathode carbon brick has good conductivity and thermal conductivity, and can significantly improve the anode current density and efficiency. Under the dual carbon background, it is expected that the transformation of electrolytic cells will gradually proceed, and the demand for graphitized cathode carbon bricks will gradually increase, with a strong demand for carbon bricks.
