高炉的合理鼓风速度

通过论述鼓风速度与风口回旋区长度的关系,提出了合理风速的概念,分析了合理风速的理论依据和影响因素,并进一步给出了判断风速是否合理的各种直观现象以及调节风速的有效方法。明确指出合理风速不是一个具体数值,而是一个合理的范围,根据高炉生产条件的变化而变化,确定合理风速需要足够时间的尝试与探索。实践证明,高炉只有在合理风速条件下生产才能保证炉缸的正常工作,才能实现高炉生产长期的稳定与顺行。

Reasonable blast velocity of blast furnace

By discussing the relationship between blast velocity and raceway length, the concept of reasonable blast velocity was put forward, further more, the theoretical foundation and influence factors of reasonable blast velocity were also analyzed in detail. What??s more, the various phenomena of blast furnace with different blast velocities and the effective methods of adjusting the blast velocity were also clearly shown. Reasonable blast velocity that is not a definite number but a reasonable controlling range should be changed according to the change of blast furnace production conditions. So that looking for the reasonable blast velocity needs enough time to attempt and explore. Practice has proved that the active hearth and the long-term stable production of blast furnace could be realized only under the condition of reasonable blast velocity.
