Technical Field

[0001] The present application relates to the field of clay bricks, and in particular to a low-porosity, high-thermal-shock clay brick for hot blast furnaces. Background Art

[0002] The application of low-porosity and high-thermal-shock clay bricks in hot blast furnaces has significant advantages. The low-porosity structure can withstand higher temperatures and is suitable for the high-temperature environment of hot blast furnaces.

[0003] Some existing porous high-thermal shock clay bricks are used by combining the clay bricks together vertically, horizontally, and then fixing them together with adhesive materials such as lime or cement. However, during construction, the clay bricks are sometimes not connected together, and the positions of the clay bricks are offset, which is inconvenient to process and reduces construction efficiency. Moreover, when the clay bricks are not in use, they need to be stacked together. The stacked clay bricks are at risk of slipping and collapsing, which increases the risk of construction.
