Continuous casting device capable of achieving continuous feeding and production of high-purity single crystal copper rods

Abstract

The invention relates to a continuous casting device capable of achieving continuous feeding and production of high-purity single crystal copper rods. The continuous casting device comprises a vacuumfurnace cover, a vacuum melting furnace, a smelting crucible, a vacuum gate valve, a thermal insulation continuous casting pot, a continuous casting crucible, a crystallizer, a cooling water jacket and a traction winding mechanism. The vacuum melting furnace is communicated with the inlet end of the thermal insulation continuous casting pot through the vacuum gate valve. The outlet end of the thermal insulation continuous casting pot is connected with the cooling water jacket and the traction winding mechanism through sealing pieces. After a raw material copper plate is melted in the smeltingcrucible, the shielding gas is introduced, the vacuum gate valve is opened, the smelting crucible tilts, the molten copper is poured into the continuous casting crucible, the liquid level of the molten copper in the continuous casting crucible is kept stable, and the traction winding mechanism carries out continuous and stable pulling to produce the high-purity single crystal copper rods. The continuous casting device has the beneficial effects that the method is reasonable and feasible, the design is ingenious, the stable and continuous uninterrupted production of the high-purity single crystal copper rods is realized, the performance is reliable, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of high-purity metal continuous casting production equipment, in particular to a continuous casting device for continuously feeding high-purity single crystal copper rods. Background technique [0002] At present, the production of single crystal copper rods in China is mostly produced by atmosphere protection melting and atmosphere protection continuous casting. Although atmosphere protection melting and atmosphere protection continuous casting can continuously produce single crystal copper rods, it is guaranteed that high-quality and high-purity single crystal copper rods cannot be produced. Products The quality cannot reach the 5N and 6N high-purity standards. There is also continuous casting after vacuum melting and filling with protective gas. The product quality can reach 5N and 6N high-purity standards, but it cannot be continuously fed. Continuous production of single crystal copper rods can only be ...

Problems solved by technology

[0005] In order to solve the problem that most existing factories need to adopt hot-type continuous casting in the production of single crystal copper rods, to form single crystals, a qualified single crystal copper rod must be produced at a very slow pulling speed. Generally, the diameter of copper rods is 6mm and 8mm. , the traction speed is only 10-30mm / min, the output is very small, the vacuum melting process is adopted, the production capacity is only for continuous production because of feeding, taking out the lead rod, closing the furnace door to vacuumize and melting, and the traction can only be carried out after constant temperature About half of the capacity, and the discontinuous production caused the about one meter long single crystal copper crystal grains drawn out at the beginning to be unqualified, unable to be used, causing waste, increasing production costs, affecting product quality and enterprise production efficiency and other technical problems, the present invention Provide a continuous casting device for producing high-purity single-crystal copper rods by continuous feeding, the method is reasonable and feasible, the design is ingenious, stable, continuous and uninterrupted production of high-purity single-crystal copper rods is provided, the performance is reliable, production costs are reduced, and production is improved purpose of efficiency
