Carbon bricks: Stable demand for blast furnace carbon bricks, fast cathode carbon bricks for electrolytic aluminum

Keywords: anti-corrosion carbon bricks


The environmental protection requirements of China's steel industry continue to rise, especially since the dual carbon target was proposed, the environmental protection requirements of the industry have been further clarified. The steel industry mainly eliminates small blast furnaces, while those that are 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. In the context of stable profit expectations for carbon bricks business and 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 varieties with higher carbon emissions in the non-ferrous metal industry. Traditional graphite cathode electrolysis cells are often built using 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. In the context of dual carbon, it is expected that the transformation of electrolytic cells will gradually proceed, and the demand for graphitized cathode carbon bricks will gradually increase, resulting in strong demand for carbon bricks.
