High-thermal-conductivity carbon brick
The invention discloses a high-thermal-conductivity carbon brick, and particularly relates to a high-thermal-conductivity carbon brick which is produced by using graphite carbon as a main raw material and is used for a blast furnace, a submerged arc furnace and a ferroalloy furnace. The technical problem to be solved is as follows: the service life of a furnace lining is influenced by low thermal conductivity coefficient of a carbon brick for the blasting furnace, the submerged arc furnace and the ferroalloy furnace, a schungite carbon brick, and a carbon brick for a calcium carbide furnace. The high-thermal-conductivity carbon brick is made from the following raw materials in parts by weight: 65-72 parts of graphite carbon, 5-8 parts of natural graphite, 5-8 parts of thermosetting phenolic resin and 15-22 parts of high-temperature coal tar pitch. According to the high-thermal-conductivity carbon brick, the heat conductivity coefficient of the carbon brick is improved, the high-temperature use performances such as molten iron corrosion resistance, oxidation corrosion resistance, alkali metal corrosion resistance and the like of the carbon brick are enhanced, the cooling of a furnace bottom and a hearth is improved, hot surface temperatures of brick linings of the furnace bottom and the hearth are reduced, so that a 'slag shell' is formed, the smelting atmosphere in the blasting furnace is allowed to be activated, and energy conservation and high efficiency of the blasting furnace, the submerged arc furnace and the ferroalloy furnace are ensured.
