Comprehensive Mathematical Model for Particle Flow and Circumferential Burden Distribution in Charging Process of Bell-less Top Blast Furnace with Parallel Hoppers

Effect of the Main Feeding Belt Position on Burden Distribution during the Charging Process of Bell-less Top Blast Furnace with Two Parallel Hoppers

“…With the extensive use of the bell-less top system in the blast furnace, many researchers studied the particle movement and size distribution in the charging process of the blast furnace. Some researchers established the single particle mathematical model to predict the burden falling point on stock surface, [1][2][3][4][5][6][7][8] which provided the theoretical guidance for blast furnace operators. Additionally, some investigators studied the size distribution and falling point of particles by small scale experiments.…”

“…On the contrary, the effective motion length of coke on the rotating chute is not same when the rotating chute rotates through the positive and negative x axis, respectively. 1) Therefore, the velocity of coke at the outlet of the rotating chute is different, then the total volume distribution of coke along the x axis direction is not symmetric. Figure 14 shows the average diameter distribution of coke in the radial direction of stock surface.…”

Data-Driven Multiobjective Optimization for Burden Surface in Blast Furnace With Feedback Compensation

“…Liu et al [10] demonstrated a concurrent monitoring method of the molten iron quality-relevant process faults, quality specific fault and process specific fault. Zhao et al [11] established a comprehensive model from flow control gate to stock surface in detail and analyzed the non-uniformity phenomenon. Shi et al [12] proposed a new stockline profile formation model and a stepped burden descending strategy to ensure the higher accuracy.…”

Investigation on the uneven distribution of different types of ores in the hopper and stock surface during the charging process of blast furnace based on discrete element method

“…Thus, the particle motion and distribution law in the hopper and the stock surface has been studied by the scholars and ironmaking workers. The research methods of particle motion and distribution law during the charging process are mainly divided into three types, physical experiment [1][2][3][4][5][6][7], single particle mathematical model [8][9][10][11][12][13][14] and discrete element method (DEM) simulation [15][16][17][18][19]. First, the cost of the physical experiment is very expensive, so it cannot be adopted as a normal research method.…”
