高炉喷煤技术推介

Introduction of BF coal powder injection

高炉冶炼中向高炉喷吹煤粉以代替部分焦炭，是节能降本、增效的有力手段；本人推介了几种比较新的高炉喷煤技术，并就包钢现状，提出了如何利用资源，提高高炉喷吹煤粉量，进一步降低成本的途径。

BF coal powder injection in place of partial coke is an effective way to energy - saving, cost - reduction, and efficiency improvement. In this paper,some new technology of BF coal powder injection is introduced,and methods to use resources, improve the total coal powder, and reduce cost are put forward.
