Mathematical Model of Burden Width in a Bell-Less Top Blast Furnace and Modeling Experimental Research

DU Peng-yu,CHENG Shu-sen,HU Zu-rui,WU Tong(School of Metallurgical and Ecological Engineering,University of Science and Technology Beijing,Beijing 100083,China)  
Opinion's concerning the uncoordinated principle between the burden width and burden trajectory width in process of iron-making,and it is fluctuated to the flows distribution of CO after charge of bell-less top to the instable status of blast furnace.In the mathematical model of burden width,it is emphasized the force to width of burden trajectory from a kinematic view point.Analyzing effect of Coriolis force to calculation of burden width and a deviate angle of maximum burden velocity,reducing error rate of horizontal width,raising segment calculate the width of burden trajectory.The mathematical model is established to adopt industrial model experimental on the ratio of 1∶10 blast furnace,the numerical model of burden width is validated to be right and rational.After applying mathematical model in a 2500 cubic meter blast furnace,in which chute angle cooperate with width burden,it is validated to burden file ration,flows stabilizing,and blast furnace smoothly working.
