上讲里己经谈到,底焦燃烧的好坏是获得高温铁水的关键。那么影响底焦燃烧好坏的主要因素又是什么呢?这就是焦炭和风。为了获得高温优质铁水,加入多少焦炭,供应多大的风量才合适呢,这就是风焦配合问题。一、焦炭数量对冲天炉熔炼的影响焦炭质量虽然是第一重要的,但是如果加人的数量不够,底焦高度过低,想用过少的焦炭化过多的铁,同样得不到高温优质铁水。焦炭的数量在冲天炉熔炼中集中表现在两个方面:一是底焦高度,一是铁焦比。因为冲天炉核心的问题就是底焦的燃烧,当炉膛直径的大小一定时,焦炭的数量就可以用底焦的高度来表示。当熔化完一批铁料时,就烧损了一部
As already mentioned in the lecture, the quality of bottom coke burning is the key to obtaining high temperature hot metal. So what is the main factor that affects the end coke combustion? This is coke and wind. In order to obtain hot high-quality hot metal, how much coke to join, how much supply of air volume is appropriate, this is the wind coke with the problem. First, the impact of coke quantity on the impact of oven melting Although the quality of coke is the first important, but if the number of people is not enough, the bottom coke height is too low, want to use too little coke too much iron, the same high temperature High-quality hot metal. The number of coke in cupola melting concentrated in two aspects: First, the bottom coke height, the first iron coke ratio. Because the problem of the cupola is the burning of the bottom coke, when the diameter of the hearth is constant, the amount of coke can be expressed as the height of the bottom coke. When melted a batch of iron, it burned a
