高炉料柱透气性问题,紧密关系着高炉的强化冶炼、能耗和生铁质量,是高炉冶炼中的极重要问题。堪称极重要问题是由高炉冶炼工艺特点所决定的:一是高炉自点火投产起连续数年甚至十年、一复一日的从不间歇作业生产;二是在既高且大的密闭竖炉里,在下降的炉料和上升的煤气流的相向运
Blast furnace column gas permeability, closely related to the blast furnace smelting, energy consumption and quality of pig iron, blast furnace smelting is extremely important issue. The most important issue is determined by the characteristics of the blast furnace smelting process: First, the blast furnace since the start of ignition for several years or even ten years, one day after another from no intermittent operations; the second is both high and large closed vertical In the furnace, the falling charge and the rising gas flow opposite each other
