Breaking Through the Blast Furnace "Black Box"
In the field of blast furnace ironmaking, understanding and controlling the smelting operation state inside the blast furnace is the key to ensuring the long-term stable operation of the blast furnace, improving production efficiency, and saving energy and reducing consumption. However, our understanding mostly relies on conventional sensor detection or traditional blast furnace visualization methods, such as top-of-furnace imaging, tuyere imaging, and laser measurement of the material surface. These methods can only provide indirect, superficial, and limited information, leaving our insight on the outside of the blast furnace "black box". The MEAI Blast Furnace Smelting Process 3D Visualization Online Auxiliary Analysis System breaks this limitation, allowing us to delve into the "black box" of the blast furnace, revealing the inner mechanism of the blast furnace smelting process in all directions and depths.
