2011年以来,邯钢为适应钢铁市场的形势,对铁前原燃料结构进行了大幅度调整,大量配加低价料,焦炭灰分和硫分大幅升高,入炉品位大幅降低,为适应原燃料的变化,邯钢邯宝公司炼铁厂2座3 200m3高炉转变操作理念,运用高炉炉腹煤气量指数和透气阻力系数指导炉况操作,炉况保持了长期稳定顺行,经济技术指标大幅提高。
Since 2011, Handan Iron and Steel to adapt to the situation of the steel market, the pre-iron fuel structure has been greatly adjusted, a large number with low-cost materials, coke ash and sulfur content increased significantly into the furnace significantly reduce the level of raw materials to adapt to the original , The operating concept of 3 200m3 blast furnaces in two steel-making plants of Handan Iron & Steel Co., Ltd. was changed, and the operation of the furnace was guided by using the blast furnace gas index and the air permeability resistance coefficient. The furnace condition remained stable and long-term, and the economic and technical indicators increased significantly .
