Abstract：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 calculate 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, it is Validated to the numerical model of burden width is right and ration. After applied mathematical model in a 2500 cubic meter blast furnace, it is validated to burden file ration, flows stabilizing, and blast furnace smoothly working.
