新冶钢“实施低成本”战略以来,铁前系统紧紧围绕公司生产要求,在外部条件劣化的背景下,始终围绕高炉的稳定顺行为基本方针,不断优化原、烧系统配矿方案;高炉通过加强原燃料管理,不断优化炉料和燃料结构,提高烧结矿、块矿和焦丁比例,不断优化高炉操作制度、提高煤比和富氧率,实现了高炉合理的煤气流分布和较高的煤气利用率,保持了高炉的长期稳定顺行;烧结固体燃耗、高炉燃料比等技术经济指标及工序制造成本不断降低,基本达到了经济炼铁的目标。
Since the implementation of the strategy of “low cost” by Xinye Steel Co., Ltd., the pre-iron system closely follows the production requirements of the company. In the background of deteriorating external conditions, the Company has been constantly optimizing the principle of stabilizing compliance with the blast furnace ; Blast furnace through the strengthening of the original fuel management, and constantly optimize the charge and fuel structure, increase the proportion of sinter ore, lump ore and coke Ding, and continue to optimize the blast furnace operating system to improve the coal ratio and oxygen enrichment rate to achieve a reasonable blast furnace gas flow distribution and more High gas utilization, maintaining the long-term stability of the blast furnace; technical and economic indicators such as solid fuel burn, fuel ratio of blast furnace and manufacturing process costs continue to drop, basically reaching the goal of economic ironmaking.
