我们对炉内煤气的热能和化学能的利用一度重视不足,加之其它方面存在一些薄弱环节,一个时期的生产出现了“三高”(焦比高、消耗高、成本高)、“二低”(产量低、合格率低)的现象。后来在兄弟厂的指导下,认识到了煤气合理分布的重要性。要克服这一薄弱环节,就得抓住主要矛盾,解决煤气在炉缸的初始分布和炉料在炉喉的初始分布,重视炉内的热能与化学能的利用,确定小高炉合理的炉喉炉气CO_2的分布曲线。由此,摸 At one time, we have noticed that “three highs” (high coke ratio, high consumption, high cost) and “two lows” (Low yield, low pass rate) phenomenon. Later, under the guidance of the brothers plant, realized the importance of a reasonable distribution of gas. To overcome this weakness, we must grasp the main contradiction, to solve the initial distribution of gas in the hearth and the initial distribution of charge in the throat, emphasis on the use of thermal energy and chemical energy in the furnace, to determine a reasonable small furnace throat furnace Gas CO 2 distribution curve. From this, touch
