Embodiment Construction
[0013] The structure and working principle of the present invention will be further elaborated below in conjunction with the accompanying drawings.
[0014] See attached figure 1 As shown, a copper melting and casting system for producing oxygen-free copper is composed of a melting furnace 1, a casting furnace 6, and a launder 2 arranged between the melting furnace 1 and the casting furnace 6, and the laundering The groove 2 makes the melting furnace 1 communicate with the casting furnace 6. In this embodiment, one end of the launder 2 is airtightly connected with the outlet of the melting furnace 1 with a concave-convex cylindrical surface, and the other end is connected with the casting furnace 6 through a gate. The outer surface of the launder 2 is provided with a casing 7, and a heat-insulating chamber 8 is formed between the inner surface of the casing 7 and the outer surface of the launder 2, and a first gas inlet is provided on the upper surface of the casing 7. Channe...

The invention relates to a copper melting and casting system for producing oxygen-free copper, comprising a melting furnace, a casting furnace, a launder arranged between the melting furnace and the casting furnace, and the launder makes the melting furnace It communicates with the casting furnace, and the outer surface of the launder is provided with a casing, and a heat-insulating cavity is formed between the inner surface of the casing and the outer surface of the launder, and a first gas chamber is provided on the casing. Into the channel, a plurality of first microholes are opened on the launder, and the first microholes make the internal space of the launder communicate with the heat-insulating cavity. The chamber structure of the heat insulation chamber can reduce the heat dissipation of the launder, reduce the occurrence of the liquid copper solidification blocking the launder, complete the transfer of the copper liquid from the melting furnace to the casting furnace, realize the low cost of the structure, and the protection of the structure The effect is good.
Description
technical field [0001] The invention relates to a copper melting and casting system, especially a copper melting and casting system for producing oxygen-free copper. Background technique [0002] Nowadays, for domestic and foreign manufacturers who use the "melting furnace-casting furnace" double furnace system to produce copper and copper alloy products, the transfer of molten copper from the melting furnace to the casting furnace is usually carried out in a closed launder, and the launder is passed through the launder Nitrogen or gas to prevent oxygen uptake. However, in the actual use process, when the length of the above launder exceeds 1m, the copper liquid is likely to be solidified and blocked due to excessive cooling, which will destroy the airtight environment and cause oxygen absorption during the treatment process. Contents of the invention [0003] The object of the present invention is to provide a copper melting and casting system, in which the phenomenon of...
