Development of a Mathematical Model to Estimate Burden Distribution in Bell-less Type Charging for Blast Furnace

Effect of Chute Angle on Charging Behavior of Sintered Ore Particles at Bell-less Type Charging System of Blast Furnace by Discrete Element Method

“…Hence many researches had been studied about the particle segregation at the charging process. [1][2][3][4][5][6][7] They gave many informative results, however, it is quite difficult to understand the segregation inside the particle bed, and grasp the segregating behavior in realtime. The particle segregation occurs at the top of blast furnace as well as at the surge hopper, the conveyor, the bunker and the chute.…”

“…A blast furnace is a huge reactor having more than 5 000 m 3 in volume for producing pig-iron from iron ore particles. Ore and coke particles are being stacked alternately in layer, and the gas having high temperature is blown from tuyeres.…”

Validation of Particle Size Segregation of Sintered Ore during Flowing through Laboratory-scale Chute by Discrete Element Method

“…Hence, many researches about the particle segregation at the charging process have been studied experimentally and mathematically. [1][2][3] However, the experimental approach is laborious, because the scale of ironmaking process is huge and there are too many operational parameters and designs of system, which affect the particle segregation.…”

Optimization of Coke Mixed Charging Based on Discrete Element Method

“…Some experimental results and quantitatively arranged models have been reported in this connection. For example, Kondo et al 7) studied the segregation behavior of ore particles at the furnace top by using Miwa's segregation model, 8) which is applicable to particle size segregation, and Okuno et al 9) developed a model that considers the change in particle size segregation caused by the deposition of burden materials based on the results of experiments and measurements in the blast furnace. Sunahara et al 10) quantified the particle segregation process at the furnace top experimentally and developed an original mathematical model which considers the influence of the particle diameter and density on segregation.…”
