近25年来,炼铁高炉呈现趋于大型化的势头,容积由1000余m~3增加到4000余m~3,每座高炉日消耗焦炭量也由1300t增加到3000~4000t。与之同时,炼焦炉开发的重点亦是增加炭化室容积,每个炭化室年产焦炭由6000t增加到16000t,一组焦炉日产焦炭由1500t增加到4000t。焦炉大型化既适应了高炉大型化的进程,又提高了炼焦的经济效益,也有利于焦炉环境的控制和改善。 1.焦炉大型化的演进由于焦炉大型化后,基本建设投资节省,占地面积减少,劳动生产率提高,生产费用下降,结果
In the past 25 years, the blast furnace of iron making tends to become large-scale. Its volume has been increased from 1,000 m 3 to 4,000 m 3, and the amount of coke consumed per blast furnace day has also increased from 1,300 t to 3,000 to 4,000 t. At the same time, the focus of the coke oven development is to increase the volume of the carbonization chamber. The annual output of coke in each carbonization chamber is increased from 6000t to 16000t. The coke production capacity of a coke oven increases from 1500t to 4000t. Large-scale coke oven not only adapt to the process of large-scale blast furnace, but also improve the economic benefits of coking, but also conducive to the control and improvement of coke oven environment. 1. The evolution of large-scale coke oven After coke oven large-scale, capital construction investment savings, land area reduction, increased labor productivity, lower production costs, the results
