Low ash carbon bricks are mainly made from electrically forged low ash anthracite coal as the main raw material, with medium temperature asphalt as the binder. After forming, they are fired at high temperatures and processed into precision bricks.

The main performance is to have low ash content and a certain thermal conductivity, which meets the needs of blast furnaces, submerged arc furnaces, electric furnaces, and can be used as lining materials for metallurgical furnaces such as submerged arc furnaces and electric furnaces.
