摘　　要： 以COREX 3000预还原竖炉炉顶的万向节布料器为研究对象,根据量纲和谐原理推导相似准数,并按照1∶5比例建立冷态模型,研究了布料器操作参数对布料规律的影响.研究结果表明:方向节布料器溜槽倾角变化对堆密度径向分布影响显著,随着倾角增大,堆密度最小值向炉墙侧移动;料线高度增加,使堆密度峰值降低,且向炉墙侧移动;溜槽转速对堆密度分布影响较小. The burden charging process was experimentally studied for the gimbal distributor of pre-reduction shaft furnace of COREX 3000.The similarity criteria were derived by dimension-harmony principle,and a 1∶5 scale cold model was constructed.The effect of distributor parameters on the behavior of burden charging was studied.The results showed that the chute inclination angle of the gimbal distributor has significant effect on the radial bulk density distribution.The position of minimum bulk density moves to the shaft wall with increasing the chute inclination angle.The peak value of bulk density decreases and its position moves to the shaft wall with the elevation of stock line.The chute rotation speed has little effect on the bulk density.
