Problems solved by technology

Thus, the problem is that when the anode is in the mold, the water that accumulates on the surface of the anode cannot be removed from the mold, but keeps interfering with the cooling process

Embodiment Construction

[0011] figure 1 , 2 and 3 show a device according to the invention for anode cooling. The anode casting device 1 comprises an anode casting wheel 2 in which an anode 4 is cast in a mold 3 . When molten metal, such as copper, is cast in the mold 3, its temperature is about 1150°C. After the anode is cast, the anode is conveyed with the rotation of the anode casting wheel 2 to the next anode casting step, ie to the cooling step. In the cooling unit 5, the surface 6 of the anode 4 is cooled in order to reduce its temperature before the anode is released from the mold. The cooling unit 5 is provided with an exhaust hood 7 through which steam generated during cooling is removed. In the cooling unit 5, cooling water 8 is supplied onto the surface 6 of the anode 4 through an upper water spray pipe 9 arranged above the anode. As the anode casting wheel 2 rotates, the anodes are conveyed to be cooled in the next cooling step, if necessary. After passing through the cooling unit, ...

Abstract

The invention relates to a method and equipment for cooling anodes (4) in connection with anode casting (1), so that in the cooling unit (5), in between cooling steps, water is removed from the anode surface at least once before removing the anode (4) from the cooling unit (5).

Description

technical field [0001] The present invention relates to methods and apparatus for cooling anodes in connection with anode casting. Background technique [0002] The blister copper produced during the conversion step of the pyrometallurgy process is further refined in the anode furnace in order to reduce the sulfur content of the blister copper. After the anode furnace treatment, the copper is cast into copper anodes by pouring molten copper into the mold. The cast copper anode is refined in copper electrolysis to become a copper anode with a copper content exceeding 99.99%. At present, widely used anode casting equipment includes a rotating casting table, and on the casting table, some casting molds are usually dozens of casting molds arranged in a circle. Usually, the casting table is provided with a cooling unit in which the workpieces are cooled in their molds by eg water. [0003] In anode casting equipment, the anode cast in the mold cannot be cooled before the surfa...
