摘要
本文对世界炼焦工业现状、高炉对焦炭质量的要求和炼焦工艺的发展作了较系统的介绍。目前全世界焦炭生产能力为4亿吨/年,1991年产量为3.332亿吨。由于高炉大型化和焦比降低,对焦炭质量的要求随之提高。在炼焦工艺发展方面,焦炉大型化,特别是大型捣固焦炉和巨型炼焦反应器值得重视。
This paper describes the worldwide status of coke making, requi rements for blast furnace coke quality and current developments of coking technologyThe present cokemaking capacities worldwide totalling 400 million tpy are installed. Back in the year 1991 the world coke production reached only 333.2 milliont. With the increase of blast furnace volume and decrease of coke ratio the requirements for coke quality are becoming more strictly. Analysing the development trend of coking technology, it is indicated that the enlargement of coke oven volume, especially stamp coke oven with a larger volume and jumbo coking reactor are attracting broadwide attentions.
