In this paper,the important way for removing alkalis is determined to be the blast furnace slag and the main way for removing zinc is determined to be the fly ash through analyzing the content of such harmful elements as K,Na and Zn in crude fuel for blast furnace of Baotou Steel as well as the balance calculation of output and discharge. Moreover,the methods and measures for reducing the enrichment of alkali and zinc in blast furnace are discussed. The effects of harmful elements on blast furnace are effectively reduced by such measures as controlling the content of alkali and zinc in incoming raw materials,dealkalizing and dezincification for scraps as well as decreasing basicity of slag and adsorption of lumpy zone.
