STUDY ON THE OFF-GAS DUST IN BLAST FURNACE

摘要

It is the general trend in steel industry that more big-scale blast furnaces were chosen in iron making. As the blast furnace is larger, the demand of the raw material strength is more. For a stable operation and the low loss of raw materials, it is important to understand the composition and characteristics of the off-gas dust. Characterization using Laser Particle Size Distribution Device, Scanning Electron Microscope and Optical Microscope were focused on the gravity dust, cyclone dust, bag-type dust formed by Qiangang 3# blast furnace.
