This invention relates to the field of
blast furnace cooling systems, specifically to a cooling
system and
intelligent control method for
high heat load zones in blast furnaces. The
system includes: cooling walls,
refractory bricks,
copper cooling elements, a composite packing layer, and an
intelligent control unit.
Copper cooling elements are spaced apart in the gaps between adjacent cooling wall sections, with the hot surfaces of the
copper cooling elements receding inwards relative to the hot surfaces of the cooling walls. The composite packing layer fills the gaps between the
copper cooling elements and the cooling walls, comprising a high
thermal conductivity packing area and a low
thermal conductivity packing area. The high
thermal conductivity packing area is located at the
mating gap between the copper cooling elements and the cooling walls, while the low thermal
conductivity packing area is located on the hot surface side of the copper cooling elements. The
intelligent control unit acquires
slag skin condition information from the
slag skin adhesion zone and dynamically adjusts the cooling parameters flowing through the copper cooling elements based on this information. This invention can improve
system heat transfer efficiency and achieve proactive and precise control of
slag skin thickness and long-term stability of the
blast furnace internal structure.
