国内大型高炉内型变化及生产指标

Analysis on the Variation of Domestic Large Blast Furnace and Production Index

摘要: 高炉是一个大型的高温反应器，目前国内高炉的发展总体趋势是朝着大型化的方向前进。高炉有效容积是表征高炉的大小最重要的参数，一个合理的高炉内型有利于实现高炉的大型化的目标，同时一个合理的高炉内型对于高炉的各项经济技术指标都是很重要的。高炉内型受高炉的有效容积、现实生产的条件和技术的发展情况等影响。本文经过对大量的高炉的设计参数进行比较得出了以下发展趋势：首先是高炉的容积越来越大，其次是高径比越来越小，喷吹燃料的占比增加。

Abstract: Blast furnace is a large-scale high-temperature reactor. The size of the effective volume of blast furnace is the most important parameter of the blast furnace, and a reasonable understanding of the inside of the blast furnace is conducive to the realization of the goal of large blast furnace. At the same time, a reasonable inner type of blast furnace is very important for economic and technical index of blast furnace. The inner type of blast furnace is affected by the effective volume of blast furnace, the condition of production and the development of technology. Through the comparison of a large number of blast furnace design parameters, the following development trends are obtained: firstly, the volume of blast furnace is getting larger and larger, and secondly, the ratio of height to diameter is increasing. The smaller the fuel is, the greater the proportion of injected fuel is.
