An experimental device for simulating the dynamic change of material level in blast furnace throat material descending process

Abstract

The invention discloses an experimental device for simulating the dynamic change of the material level in the process of falling material in the blast furnace throat, which comprises a furnace throat part, a furnace material recovery part and an arc-shaped tray part; the furnace material recovery part is installed under the furnace throat part, The arc-shaped tray part is arranged inside the charge recovery part, and the arc-shaped tray part can be raised and lowered to realize the adjustment of the edge flow velocity of the material. The invention can simulate the blanking process in the blast furnace smelting process in a cold state; at the same time, through the arc-shaped arching device placed below, the imbalance of the center and edge blanking when the furnace material passes through the furnace throat and the furnace body is simulated, and finally the furnace throat is lowered. Visualization of material surface shape during material dynamic process.

Description

technical field [0001] The invention relates to an experimental device for simulating the dynamic change of the material surface in the process of material descending in the furnace throat, which can reproduce the material distribution process of the blast furnace and the furnace material descending process in the experiment. It can also measure the charge surface shape and charge distribution under different center and edge flow velocities of the charge; study the charge movement status and charge surface shape change of the blast furnace during the intermittent period of charge distribution. It involves the intersection and integration of various disciplines such as metallurgy, computer science, mathematics, control science and motion control. Background technique [0002] Nowadays, in order to respond to the national call for energy conservation and emission reduction, small and medium-sized iron and steel enterprises have gradually faded out of the historical stage, and ...

Problems solved by technology

[0003] However, due to the particularity and complexity of the internal environment of the blast furnace, it is difficult to conduct actual measurement research. Therefore, many blast furnace researchers use small-scale experimental models to simulate the blast furnace production process as a research method; however, the blanking process of the blast furnace is accompanied by high temperature, closed In a special environment, there is an imbalance between the center and the edge of the blanking. How to simulate the dynamic blanking process of the blast furnace in the experimental model has always been an unresolved difficulty.
