Product Introduction
Carbon bricks are made of high-quality electric calcined anthracite and high thermal conductivity graphite as raw materials, coal tar as binder, and are formed by high pressure pressing and high temperature baking. Rongsheng carbon bricks have good corrosion resistance and high thermal conductivity that can easily form a cooling protective layer. It is mainly used in the hearth and bottom of blast furnaces.
