This invention relates to a water-cooled pipe for the bottom of a blast furnace, belonging to the field of metallurgical industry. The water-cooled pipe (2) is arranged at the bottom of the blast furnace, divided into an inner ring region, a middle ring region, and an outer ring region from the inside out according to the distance from the center of the blast furnace. The diameter of the water-cooled pipe (2) in the inner ring region is smaller than that in the middle ring region, which is smaller than that in the outer ring region. The cooling intensity gradually decreases from the outside to the inside, forming a pot-bottom erosion curve (1) inside the blast furnace hearth, thereby increasing the core temperature of the blast furnace hearth. This invention can enhance the cooling of the elephant foot region of the hearth, slow down the erosion of the refractory material in the elephant foot region, reduce the diameter of the middle ring pipe, reduce the cooling area, and minimize the diameter of the inner ring pipe, resulting in the smallest cooling area. The cooling intensity gradually decreases from the outside to the inside, thus forming a pot-bottom erosion, while simultaneously increasing the core temperature, ensuring the hearth is active, and extending the hearth's lifespan.
