为了延长高炉寿命,济钢第一炼铁厂1993年在新建5号、6号(350m~3)高炉采用了高炉铝炭砖炉衬。砌筑部位自渣口中心线以上(与炉缸内砌的自焙炭块接茬)至炉身支梁水箱上沿。1994年3号高炉中修及2号高炉大修也同样采用了铝炭砖。实践表明,高炉铝炭砖具有良好的耐磨性、异热性等优点,使用该砖砌筑炉衬的高炉能够强化冶炼,并能延长寿命。
In order to prolong the life of the blast furnace, the first ironworks of Jinan Iron and Steel Co., Ltd. adopted blast furnace aluminum-carbon brick lining in No. 5 and No. 6 (350m ~ 3) blast furnaces in 1993. Masonry parts from the slag mouth above the center line (with the hearth of self-baking charcoal block stubble) to the shaft of the furnace supporting beam tank. No. 3 blast furnace repair in 1994 and No. 2 blast furnace overhaul also used aluminum charcoal brick. Practice shows that the blast furnace aluminum charcoal brick has good wear resistance, heat and other advantages, the use of the brick lining of the furnace can enhance smelting, and can extend the life expectancy.
