性の悪いものであつた。 The object of the present invention is to improve the air blowing pipe provided on the side wall of the reaction tower of a flash smelting furnace as described above. That is, in order to improve the smelting reaction, it is necessary that the air blown from the air blowing pipe 7 of the flash smelting smelting furnace as described above has an appropriate discharge speed (approximately 100 m/s or more). When changing the operating conditions of the flash smelting furnace, it becomes necessary to change the amount of air blown from the air blowing pipe 7. In that case, the diameter of the air blowing tube 7 must be changed in order to maintain the above-mentioned appropriate discharge speed, but conventionally, the air blowing tube has been replaced with an air blowing tube of a different diameter each time. However, because deposits (pine room) are formed at the end of the air blowing tube on the reaction column side, it takes a long time to remove and install the air blowing tube, making it extremely difficult to work. It was hot.
