2. Description of the Related Art A PS converter used for refining copper is one in which a cylindrical furnace body is placed horizontally, and magnesia or
It is lined with chrome and magnesia bricks and can be tilted back and forth by an electric motor for convenient insertion and ejection. There are many tuyeres on the lower side of the furnace.
Pressurized air having a gauge pressure of about 100 kPa (1 kg / square centimeter) is blown into the molten mat.

The operation is batchwise and the slag generation period (building period)
And the copper-making period, and F in the mat during the slag generation period
e is removed as slag. This slag generation period is 2-3
Repeated times, after reaching a certain amount of white glue formed, it enters the copper-making period to obtain blister copper. In both the slag generation period and the coppermaking period, the heat source uses the heat of oxidation of sulfide, and no fuel is used. In particular,
Since the reaction heat becomes excessive during the copper-making period, the temperature rise is controlled by adding cold materials such as anode cast-back material (electrolytic residue copper) generated during electrolysis, smelter repeats, and copper scrap. .

Conventionally, when a cold material is charged into a converter, the operation is temporarily stopped to open the front hood, and the converter is placed from the exhaust gas hood side so that the tip of the boat for charging the cold material is the converter. Tilt to the front side to the position toward the insertion / exhaust port.
Then, the cold material is loaded by suspending a cold material loading boat containing a large amount of anode cast material, repetitive products, copper scrap, etc., which are generated by an overhead crane. After the charging is completed, the converter is rotated in the opposite direction so that the insertion / exhaust port of the converter is on the exhaust gas hood side, and the front hood is closed to resume operation. Therefore, the time required to put in the cooling material is wasted in the operation, which has been a factor to hamper improvement in productivity.
