ResumoThe formula of the bell-less top burden distribution is modified.The modified equation is n={l20cos2β+2l0cosβLx+ [1+(4π2ωl20/C21)L2x]}1/2-0.38.The burden distribution rule of the first blast furnace of the Nanjing Iron and Steel Corp.is simulated in the lab using the 1:7 model.The adaptive burden distribution C32C30C30C28 and the center adding coke α=17o are given.The differences of the chute angle as the different stock line heights are calculated.
