PURPOSE:To make the exchange of a cooler due to wear unnecessary by dividing the cooler into plural chambers along the direction of a furnace and connecting flowing water pipes to each of the chambers to form separate water feeding and discharging system. CONSTITUTION:A cooler 1 for cooling a vertical furnace such as a blast furnace is divided into a top cooling chamber 2 and a rear cooling chamber 3 with a partition wall 8. A flowing water path 11 is formed in each of the chambers 2, 3 with alternately projected partition walls 9, and flowing water pipes 4, 5 and 6, 7 are connected so as to feed and discharge water. The cooler 1 is inserted into brick 21 through the iron shell 22 of the shaft of a furnace. Even when the cooler 1 is worn out owing to the wearing of the brick 21, the exchange of the cooler 1 is not required, and the amount of cooling water can be regulated.
