(1) The bottom and hearth of blast furnaces with long service life, especially in areas with abnormal corrosion, should use micropores with high thermal conductivity, strong resistance to thermal stress, strong resistance to alkali metal corrosion, strong resistance to CO decomposition reaction, and strong resistance to iron penetration. Ultra microporous carbon brick or microporous semi graphite brick.
(2) The reaction between ceramic additives and binders in carbon bricks can improve the ability of binders in carbon bricks to resist corrosion by molten iron. Ultra microporous carbon bricks are most suitable for the abnormally corroded parts of furnaces.
(3) The design concept of modern blast furnace bottom and hearth carbon bricks should be based on the optimization of cooling system and hearth geometry structure. Firstly, consider the various performance indicators of using carbon bricks, rather than the shape and appearance of the carbon bricks. The shape and size are independent of whether ceramic cups are used in the furnace. Blast furnace carbon bricks need to be stored after use. To ensure the quality and effectiveness of carbon bricks, they need to be stored scientifically. When storing, attention should be paid to moisture-proof, sun protection, fire prevention and other measures to avoid damage or deterioration of carbon bricks.
Xinghui New Materials produces acid resistant and anti-corrosion carbon bricks using a unique process, using high-quality graphite carbon materials and adding highly acid resistant organic composites. They are refined through high-pressure molding, vacuum impregnation, and high-temperature heat treatment processes, and have extraordinary acid and temperature resistance. They are ideal lining materials for chemical phosphoric acid reaction tanks, phosphoric acid storage tanks, and other equipment; Our company has formed a one-stop operation pattern and service system for scientific research and design, production and sales, and on-site construction. Can produce according to user requirements and fully meet customer demands. Welcome new and old customers to call or write to discuss cooperation matters.
