Description
Technical Field
The utility model belongs to the field of metallurgy, and particularly relates to a component for copper smelting.
Background
In the metallurgical field, especially in the process of producing high-purity copper, the prior art only recognizes that the oxygen content in the product affects the quality of the final product, when copper is drawn to produce copper wires, especially when ultra-fine copper wires with the diameter smaller than 0.05mm are drawn, micro oxygen bubbles mixed in raw materials are broken in the drawing process to cause copper powder to be produced in the production process, the copper wires to be broken, and the like, and even if the micro oxygen bubbles are not broken, the performance of the final product is affected, so people always strive to deoxidize in the process of producing high-purity copper, and the performance of the product is improved.
We have found under investigation to continuously increase the demand for high purity copper filaments that the hydrogen in the raw material has a greater influence than oxygen. Also, the hydrogen content and the oxygen content were 1ppm by weight, and the volume of hydrogen was 16 times that of oxygen. Further research has found that copper powder produced during drawing copper wire filaments, paint nodules and pinholes produced during painting copper wire filaments are all related to the hydrogen content of the raw material. Therefore, in order to improve the performance of the high-purity copper wire filament, it is necessary to perform dehydrogenation treatment in addition to deoxidizing the high-purity copper.
Lithium metal is an active metal which is easy to combine with oxygen, nitrogen, sulfur and the like, is often used as a deoxidizer and a desulfurizing agent in the metallurgical industry, and is an optimal material for removing impurities in the processing process of a plurality of special alloy steels. Lithium metal reacts readily with hydrogen at around 500 ℃ to produce lithium hydride, which is the only alkali metal that can produce a stable enough hydride that melts without decomposing, and can be used as a dehydrogenation agent.
Since the density of metallic lithium is very small, only 0.534g/cm 3 Is the lightest of all metals, and the density of copper in the molten state is 7.85g/cm 3 If the metal lithium is directly put into the liquid copper, the metal lithium floats on the surface and reacts unevenly with oxygen and hydrogen in the liquid copper, and is not consumed by external oxygen and the like, so that the metal lithium cannot be directly put into use.
In order to solve the difficulty, the prior art generally prepares lithium into copper-lithium alloy, the property of the copper-lithium alloy is relatively stable, the copper-lithium alloy is easy to store, the copper-lithium alloy is high in density, the copper-lithium alloy can sink when being put into liquid copper to realize full reaction with copper liquid, the copper-lithium alloy is very troublesome to put into a copper smelting furnace, on one hand, the copper-lithium alloy needs to be smashed when being used, copper-lithium alloy fragments are splashed onto human skin, metal lithium can corrode the skin, so that protective articles need to be worn in the operation process, and the copper-lithium alloy itself also contains other impurities, so that new impurities are added in the process of removing hydrogen and oxygen, and the product effect is poor. In addition, when copper-lithium alloy is put into liquid copper, charcoal or graphite layer on the surface of copper liquid needs to be pulled or splashed, so that more oxygen is brought into the copper liquid in the copper smelting furnace pool.
In order to solve the problems, a new structural form of dehydrogenation deoxidizer needs to be manufactured, so that hydrogen and oxygen in the metal copper are effectively removed.

The appropriate copper tube thickness allows the assembly for copper smelting to melt during the firing-through the crystalline flake graphite protective layer-into the bottom of the bath-up. The component for copper smelting is too thin, and the copper shell is melted too early, so that metal lithium can be scattered on the surface of the copper liquid; too thick, the melting speed is too slow, so that the component floats to the surface of the copper liquid again, and the metal lithium can be scattered on the surface of the copper liquid, so that the degassing effect is reduced.

Detailed Description
For a better understanding of the objects, structures and functions of the present utility model, a copper-clad lithium dart structure of the present utility model will be described in further detail with reference to the accompanying drawings.
Specific example 1:
as shown in fig. 1 to 3, an assembly 3 for copper smelting (hereinafter simply referred to as an assembly 3) includes a copper tube 1 and metallic lithium 2, the metallic lithium 2 being wrapped in the copper tube 1. The relative density of the whole assembly 3 for copper smelting can be adjusted by controlling the thickness of the copper pipe 1, so that the assembly 3 for copper smelting is beneficial to throwing and using; on the other hand, the metal lithium 2 is metal with stronger metal mobility, and is similar to potassium and sodium, and the metal lithium 2 is more easily stored and used in a form of an assembly 3 for copper smelting, wherein the assembly is required to be stored in an air-isolated manner; furthermore, the form of copper-coated lithium is selected for copper smelting, so that no new impurities are brought.
The two ends of the copper pipe 1 are hermetically sealed, one end of the copper pipe is made into a spearhead structure, the length of the copper pipe is about 20mm, and the other end of the copper pipe is of an airfoil structure. One end of the component for copper smelting is made into a spearhead structure to serve as a throwing end, when the component is vertically thrown into copper liquid to be dehydrogenated and deoxidized, resistance penetrating through a slag layer and entering the copper liquid can be reduced, the component can enter the bottom of the copper liquid more easily, and metal lithium with low density is prevented from floating and burning on the surface of liquid copper; the other end is of an airfoil structure, so that the running direction can be kept unchanged in the throwing process until the copper liquid enters the bottom of the copper liquid.
Wherein, the specification of the copper pipe 1 isThe total length of the copper tube 1 is 100mm, and the proper thickness of the copper tube 1 ensures that the components for copper smelting are completely melted in the process of entering copper liquid and in the process of floating. The proper wall thickness of the copper pipe 1 ensures that the copper pipe has proper relative density, and can accurately control the depth of a component for copper smelting to be thrown into liquid copper in cooperation with a certain throwing speed,meanwhile, different wall thicknesses have different melting times, and by selecting proper wall thicknesses, the component for copper smelting can be controlled to be completely melted in the sinking process after copper liquid is added, or completely melted in the whole sinking process and part of the floating process. If the component for copper smelting is too thin, the component is just put into molten copper, the copper shell is completely melted, and metal lithium can be gathered on the surface close to the liquid level, so that the metal lithium cannot fully react with oxyhydrogen in the copper liquid, and the situation that the molten copper is completely melted just after the copper is put into the component is avoided; too thick the component 3 will still not melt down to the bottom of the bath, and the overall density of the component 3 will be lower than that of the bath, so that the component 3 will either float up again, resulting in a complete melting of the component 3 at the surface of the bath, scattering of metallic lithium near the surface of the bath, and likewise reducing the degassing effect. The metal lithium 2 is the metal lithium 2 with the purity of more than 99.99 percent, and the high-purity metal lithium is beneficial to improving the dehydrogenation and deoxidation effects of the oxygen-free copper and reducing impurities.
The front end copper wall of the assembly 3 for copper smelting is thinner than the wall of the copper pipe 1, the copper pipe 1 is melted before the front end of the assembly 3 for copper smelting is melted, after the front end of the assembly 3 for copper smelting enters copper liquid, the front end of the spearhead is heated and melted, internal metal lithium 2 begins to disperse downwards and inwards of the copper liquid, the metal lithium 2 can be rapidly dispersed everywhere, the dispersing direction is towards the inside of the copper liquid, material waste caused by the surface diffusion of the copper liquid is avoided, oxygen and hydrogen in the copper liquid react to replace hydrogen elements and oxygen elements in the copper liquid, meanwhile, when the gas brought in when the metal lithium 2 is filled into the copper pipe 1 is heated and expanded, the gas is sprayed downwards and escapes from the spearhead end, when the wall thickness of each direction of the copper pipe is consistent, the internal gas is prevented from being expanded at high temperature to cause uncontrollable explosion, in that case, the metal lithium is to be put in the position randomly, uncontrollable, and on-site operators have operation risks.
When the assembly 3 for copper smelting is used, the spearhead of the assembly 3 for copper smelting faces the copper liquid level to be dehydrogenated and deoxidized, a certain initial speed is given to the assembly 3 for copper smelting to enter the copper liquid to be dehydrogenated and deoxidized, after the assembly 3 for copper smelting enters, explosion phenomenon does not exist, and after the copper liquid enters, the complete melting reaction disappears about 0.5S.
Wherein, make copper smelting subassembly 3 have certain initial velocity to get into the copper liquid of waiting dehydrogenation deoxidization, can be through handheld copper smelting subassembly 3, make its have certain height from the copper liquid level, fall into copper liquid in the form of free fall and realize. Calculating the approximate drop height of the assembly 3 for copper smelting according to h=k (ρ1- ρ2)/ρ 2*H; in the formula, the copper liquid depth is H, the falling point of the component 3 for copper smelting is H from the liquid level, the copper water density rho 1, the component 3 density rho 2 for copper smelting, the viscosity of the copper liquid and the slag layer resistance are corrected by the coefficient K, and the K=1.5-3 is higher in viscosity, the slag layer is thicker, and the K value is higher in temperature. Through several height adjustment experiments, it is possible to inject the assembly 3 for copper smelting into the copper bath with a suitable initial velocity. In this example, the copper bath temperature was 1160℃and the copper tube 1 gauge wasThe total length of the copper pipe 1 is 100mm, the length of the spearhead structure is about 20mm, the copper smelting assembly 3 is released in a state of zero initial speed at the position 500mm away from the liquid level of the copper liquid, and the copper smelting assembly 3 can be completely melted and diffused in the process of entering the copper liquid and the floating process through falling into the copper liquid in a free falling mode. Of course, in order to ensure personal safety of workers, the projection tool can be designed independently, so that the situation that an operator is too close to molten copper is avoided, for example, a slide way is arranged, and the assembly 3 for copper smelting is released from a certain height, slides along the slide way and the like can be realized.
Sampling detection shows that the component is fully utilized to carry out dehydrogenation and deoxidation treatment on the copper liquid, the oxygen content in the copper liquid can reach 2ppm, the hydrogen content can reach 0.8ppm, and the general oxygen content of the results of dehydrogenation and deoxidation carried out in other modes in the prior art can only reach about 10ppm, and the hydrogen content can only be controlled to about 1.5ppm, so that the scheme greatly reduces the hydrogen and oxygen content in the finished product.
