India Self Roasting Carbon Brick - Rongsheng Kiln Refractory
India The working layer can be semi-graphite block or self-baking carbon block. Both material have been proved to have good erosion resistance and good overall structure strength. The high-alumina and clay brick in the permanent layer is oxidation-resistant and erosion resistant.
India Semi Graphitic Cathode Bottom Block
India In large capacity blast furnaces, semi graphite self baking carbon bricks are adopted, which can not only decrease liquid iron melt index, but also increases thermal conductivity, enhances alkali corrosion resistance, improves oxidization resistance, increases washing abrasion resistance and reduces residual shrinkage.
India Carbon Brick for Blast Furnace - Rongsheng Refractory
India The semi-graphite Cathode Bottom Block is made of electric calcined coal, petroleum coke, asphalt, artificial graphite and other materials, and formed by molding, roasting and machining. The semi-graphite Cathode Bottom Block has a low degree of graphitization or only partial graphitization, with a resistivity of 15-45 μΩ·m.
India China Carbon Brick For Blast Furnace Hearth Manufacturers ...
India In late 1970s and 1980s, new type blast furnace bricks are developed, such as impregnated high density carbon bricks, semi graphite carbon bricks which adopts electric calcined anthracite as raw material, semi graphite SiC carbon bricks added with a little amount of silicon carbide, micro pore carbon bricks added with pure silicon, silicon ...
