离散单元法高炉无钟炉顶布料模拟研究

ON SIMULATION OF CHARGING IN BELLLESS TOP BLAST FURNACE WITH DISTINCT ELEMENT METHOD

从动力学角度，采用离散单元法研究炉料颗粒的受力和运动，建立高炉无钟炉顶布料数值计算模型，模拟无钟炉顶布料过程和料面形状。模拟与实测对比表明，两者基本吻合，证明离散单元法在高炉无钟布料应用中可行，并为高炉无钟炉顶布料的机理研究开辟了一条新的途径。

In this paper,the distinct element method is adopted to study the force and the motion of granular burden from a kinematic view pointThe numerical model of bellless top charging is establishedThe charging process and burden surface profile have been imitatedThe comparison made between simulation results and measured results,where the two results basically coincide with each otherIt proves that the application of the distinct element method to blast furnace bellless top charging is feasible which has also provided a new approach in theoretical study of bellless top charging
