氧气顶吹转炉炉衬寿命的高低与炉衬砖材质直接有关。我国制作炉衬砖的主要材料一直用天然白云石,由于其氧化镁含量低、杂质多、易水化,影响炉衬寿命的提高。用海水为主要原料人工合成的镁质白云石制作炉衬砖,则可从根本上改变这一状况。南京钢铁厂以阶级斗争为纲,贯彻“鞍钢宪法”精神,实行工人、干部、技术人员和生产、科研、与使用单位两个三结合,开展了用海水合成镁质白云石制作炉衬砖的群众性试验研究工作。该厂在空气侧吹转炉风眼部位试用取得初步成果后,又在15吨氧气顶吹转炉上试用。经过11天时间一个炉役期的吹炼,产钢6845吨,与去年同期炉役平均产钢量 Oxygen top blown converter lining the level of life and lining brick material directly related. The main material used to make lining bricks in our country has always been using natural dolomite, because of its low content of magnesium oxide, impurities, easy to hydration, affecting the lining life. With seawater as the main raw material synthetic magnesia dolomite lining brick, you can fundamentally change the situation. Nanjing Iron and Steel Plant to class struggle as the key link, implementing the spirit of “Ansteel Constitution”, the implementation of workers, cadres, technicians and production, research, and the use of two units of the three together to carry out the use of sea magnesia dolomite production lining brick masses Sexual testing research work. The plant in the air side of the converter wind eye parts trial to obtain preliminary results, but also in the 15 tons of oxygen top-blown converter trial. After 11 days of a furnace campaign blowing, producing 6,845 tons of steel, with the same period last year, the average amount of steel production
