도 1은 본 발명의 플로우챠트1 is a flow chart of the present invention
도 2는 본 발명의 열간압연 판재 제조공정을 나타낸 도면이다2 is a view showing a hot rolled sheet material manufacturing process of the present invention.
〈도면의 주요부분에 대한 부호의 설명〉<Explanation of symbols for main parts of drawing>
1:리튬인고트 2:진공열처리 압연로1: lithium ingot 2: vacuum heat treatment furnace
3:롤러 4:권취기3: roller 4: winding machine
본 발명은 금속리튬 정제판 제조방법에 관한 것으로, 특히 탄산리튬을 진공로에 장입하여 진공증류 정제함으로 금속리튬을 얻고 이어 금속리튬으로부터 인고트를 제조한 후 알곤가스가 투입된 전기로에서 연간압연하여 판재를 제조하기 위한 것이다.The present invention relates to a method for manufacturing a metal lithium tablet plate, in particular, by charging lithium carbonate into a vacuum furnace to obtain a metal lithium by vacuum distillation purification, and then to produce an ingot from the metal lithium plated by rolling annually in an electric furnace in which argon gas is injected To prepare.
일반적으로 금속리튬은 비중이 0.6이고 융점이 180℃이며, 끓는 점이 1400℃인 금속으로, 융점(180℃)의 약간 위까지 가열하면 급격히 산화하여 연소된다.In general, metal lithium is a metal having a specific gravity of 0.6, a melting point of 180 ° C., and a boiling point of 1400 ° C., and is rapidly oxidized and burned when heated to slightly above the melting point (180 ° C.).
본 발명은 이와 같은 종래의 결점을 해소하기 위한 것으로, 본 발명의 목적은, 탄 산리튬으로부터 금속리튬을 정제하고, 정제된 금속리튬을 공기와의 접촉을 차단한 설비에서 용해한 후 인고트를 제조하며, 제조된 인고트를 알곤가스가 투입된 특수고안된 전기로에서 열간압연하여 판재를 생산할 수 있도록 하는 금속리튬 정제판 제조방법을 제공하는데 있다.The present invention is to solve such a conventional drawback, the object of the present invention is to purify the metal lithium from lithium carbonate and to dissolve the purified metal lithium in a facility that blocks contact with air to produce an ingot In addition, to provide a method for manufacturing a metal lithium tablet plate to hot-roll the manufactured ingot in a specially designed electric furnace in which argon gas is injected.
이와 같은 목적을 달성하기 위한 본 발명은 탄산리튬을 온도 800℃-1100℃, 진공도 
이하, 본 발명의 실시예를 첨부도면을 참고로 하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1공정은 금속리튬 정제공정이다.The first step is a metal lithium purification step.
즉, 탄산리튬을 온도 800℃-1100℃, 진공도 
여기서, 탄산리튬은 730℃이상의 온도로 가열하면 CO2가스를 발생하여 분해를 시작하며 730℃부터 탄산가스가 제거되기 시작하여 결국 리튬만 남게 된다.Here, lithium carbonate starts to decompose when heated to a temperature of 730 ° C or higher, and carbon dioxide gas starts to be removed from 730 ° C, leaving only lithium.
제2공정은 금속리튬 인고트 제조공정이다.The second step is a metal lithium ingot manufacturing step.
이 공정은 리튬가루를 뭉치기 위한 공정으로, 금속리튬을 온도 400℃-450℃, 진공 도 
여기서, 금속리튬 인고트란 압연전 소재를 말하는 것으로, 예를 들어, 우리는 철판, 철봉 등의 무수히 많은 철제 제품을 쓰고 있는데 이러한 철판 혹은 철봉등이 만들어 지는 과정은 커다란 금속 덩어리를 쭉쭉 잡아당기는 인발기계에 넣어 제조하며, 이때 쓰이는 커다란 금속 덩어리를 인고트라고 한다.Here, metal lithium ingot is a material before rolling, for example, we use a myriad of iron products such as iron plate, iron bar, etc. The process of making such iron plate or iron bar is a drawing machine that pulls a large metal block straight Ingots are large chunks of metal used to make them.
제3공정은 열간압연 판(板)재 제조공정이다.The third process is a hot rolled sheet material manufacturing process.
이 공정에서는 리튬 인고트(1)를 진공 열처리 압연로(2)내에서 다수의 압연기 롤러(3)를 거쳐 권취기(4)를 통해 리튬 판재를 권취하는 것으로, 이때의 진공 열처리 압연로(2)의 열처리 온도는 120℃-140℃, 진공도는 
이상에서 설명한 바와 같은 본 발명은 열간압연판을 안전하게 제조할 수 있으며, 압연판(금속리튬)의 순도를 증가시킬 수 있는 효과가 있다.As described above, the present invention can safely manufacture a hot rolled plate, and has an effect of increasing the purity of the rolled plate (metal lithium).
