본 고안은 금속의 연속합금 주조장치에 관한 것으로, 특히 용융점의 차이가 크거나 비중의 차이가 큰 비철금속의 합금 및 주조가 연속으로 이루어지도록 한 금속의 연속합금 주조장치에 관한 것이다.The present invention relates to a continuous alloy casting device of the metal, and more particularly to a continuous alloy casting device of a metal so that the alloy and casting of non-ferrous metal having a large difference in melting point or a large difference in specific gravity.
일반적으로 수평연속주조기를 이용하여 합금주조재를 만드는 경우 주조전에 주금속 용탕에 첨가금속을 투입하고 교반한 후 주조를 하게 된다. 그러나 주조속도가 충분히 빠르지 못하면 합금용탕이 유지로에서 장시간 머물게 되어 합금용탕은 첫째, 비중차이에 의해 편석이 발생하여 주조재의 합금조성이 균일치 못하게 되고, 둘째, 첨가금속의 증발온도가 낮을때에는 첨가금속의 용융시 다량의 가스가 발생하거나 증발하면서 재료의 손실은 물론 정확한 조성을 맞추기 어렵게 되며, 작업장내를 오염시켜 작업자의 건강에 악영향을 주기도 한다.In general, in the case of making an alloy casting using a horizontal continuous casting machine, the additive metal is added to the molten metal of the main metal before casting, and then the casting is performed. However, if the casting speed is not fast enough, the molten alloy will stay in the holding furnace for a long time. First, segregation will occur due to the difference in specific gravity, so that the alloy composition of the casting material is not uniform. Second, when the evaporation temperature of the additive metal is low, it is added. When the metal is melted, a large amount of gas is generated or evaporated, so that the loss of materials, as well as the exact composition, becomes difficult, and contaminates the workplace, adversely affecting the health of the worker.
상기와 같은 문제점을 해결하기 위한 본 고안은 합금주조된 금속이 일측의 하단으로 연속 토출되는 수평연속 주조기에 합금 모재를 넣은 다음 뚜껑으로 밀폐시키고, 상기 뚜껑에는 하단에 다수의 미세공이 천공된 흑연중공봉을 하향설치하면서 첨가 금속을 넣은 상태에서 중앙의 공급공으로 불활성가스를 적정량씩 공급하도록 한 가압편을 삽입 설치함으로써 합금주조되는 상태에 따라 첨가 금속을 적절히 공급하면서 내부가 산화분위기로 되는 것을 방지함은 물론 교반의 효과를 증대시킬 수 있도록 한 것이다.The present invention for solving the above problems is to put the alloy base material in a horizontal continuous casting machine in which the alloy casting metal is continuously discharged to the bottom of one side and then sealed with a lid, the lid is a hollow hole in which a plurality of fine holes perforated By inserting the press piece which supplies the inert gas to the central supply hole by the proper amount while installing the rod downwards, the inside of the rod is prevented from oxidizing atmosphere while supplying the additive metal properly according to the alloy casting state. Of course it is to be able to increase the effect of the stirring.
이하 본 고안을 첨부 도면에 의거 상세히 기술하여 보면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
일측 하단에 로울러(2)(3)에 의해 합금주조된 금속이 토출구(4)를 통해 토출되는 수평연속 주조기(1)는 뚜껑(5)에 의해 밀폐되도록 하고, 상기 뚜껑(5)을 통해 상단부의 일부가 노출되도록 하단에 다수의 미세공(7)이 구비된 흑연 중공봉(6)을 내장하고, 상기 흑연중공봉(6)의 상단에는 가스의 공급공(9)이 구비된 가압편(8)을 상하로 이동할 수 있도록 삽입 설치하여서 된 것이다.The horizontal continuous casting machine 1 in which the alloy cast metal is discharged through the discharge port 4 by the rollers 2 and 3 at one lower end thereof is sealed by the lid 5, and the upper part through the lid 5. A built-in graphite hollow rod 6 having a plurality of micropores 7 at a lower end thereof to expose a portion of the pressurized piece having a gas supply hole 9 at an upper end of the graphite hollow rod 6. 8) is inserted and installed to move up and down.
이와같이 구성한 본 고안의 금속의 연속합금 주조장치는 수평연속 주조기(1)의 내부와 흑연 중공봉(6)의 내부에는 용융온도의 차이가 크거나 비중의 차이가 많이 나는 금속을 각각 넣는 것으로서, 비중이 8.89g/㎤인 동(Cu)과 비중이 1.73g/㎤인 마그네슘(Mg)을 넣거나, 용융온도가 1083℃ 정도인 동을 수평연속 주조기(1)에 넣으면서 용융온도가 각각 320.9℃와 650℃ 정도이고 비등온도가 각각 765℃와 1107℃ 정도인 카드뮴(Cd)과 마그네슘(Mg)을 흑연중공봉(6)에 넣도록 함으로써 합금원소의 일부가 뜨거나 가라앉으면서 골고루 혼합되지 않는 현상이나 또는 용융점이 큰 금속을 녹이는 동안 용융점이 낮은 금속이 비산되거나 다량의 가스가 발생되는 현상 등을 방지하면서 잘 섞인 합금주조 금속을 얻도록 하는 것이다.The continuous alloy casting device of the metal of the present invention configured as described above includes a metal having a large difference in melting temperature or a large difference in specific gravity in the horizontal continuous casting machine 1 and the graphite hollow bar 6. The 8.89 g / cm 3 copper (Cu) and the specific gravity of 1.73 g / cm 3 magnesium (Mg) are added or the copper having a melting temperature of about 1083 ° C. is placed in the horizontal continuous casting machine 1, and the melting temperatures are 320.9 ° C. and 650, respectively. Cadmium (Cd) and magnesium (Mg), each having a boiling temperature of about 765 ° C and 1107 ° C, are placed in the graphite hollow rod (6) so that a part of the alloying elements do not mix evenly while floating or sinking. Alternatively, while melting the metal with a large melting point, a metal alloy with a good mixing is obtained while preventing a metal having a low melting point from scattering or generating a large amount of gas.
즉, 수평 연속 주조기(1)에는 동을 충진시킨 상태에서 어느정도 가열시킨 후 용융점이 낮은 카드뮴이나 마그네슘을 흑연중공봉(6)에 넣고 잠시 가열시키면서 가압편(8)을 적절히 하향이동시켜 그 혼합되는 정도의 조절이 이루어지도록 한다.That is, the horizontal continuous casting machine 1 is heated to a certain degree in the state of filling copper, and then the cadmium or magnesium having a low melting point is placed in the graphite hollow rod 6, while the pressure piece 8 is appropriately moved downward while being mixed for a while. Adjust the degree.
가압편(8)이 계속 하향 이동하므로 밀려서 미세공(7)으로 토출되는 첨가금속(카드뮴이나 마그네슘)의 양이 끝까지 적정량으로 유지되고, 합금주조된 금속은 일측의 토출구(4)를 통해 로울러(2)(3)에 의해 강제 토출된다.Since the pressing piece 8 continues to move downward, the amount of the additive metal (cadmium or magnesium) that is pushed and discharged into the micropores 7 is maintained at an appropriate amount until the end, and the alloy-cast metal is rolled through the discharge port 4 on one side ( It is forcibly discharged by 2) (3).
그리고 흑연중공봉(6)의 가압편(8)에 형성한 공급공(9)을 통해 불활성 가스를 적절히 공급하여 내부가 산화 분위기로 변화되는 것을 방지한다.Then, the inert gas is appropriately supplied through the supply hole 9 formed in the press piece 8 of the graphite hollow rod 6 to prevent the inside from being changed into an oxidizing atmosphere.
따라서 본 고안의 금속의 연속합금 주조장치에 의하여서는 불활성 가스를 공급하면서 첨가금속이 주금속 용탕과 섞일때 발생하게 되는 다량의 가스방출을 억제하고 증발온도가 낮은 첨가금속일 경우 증발에 따른 재료의 손실량을 줄이고 그에따른 작업장내의 환경오염을 억제할 수 있으며, 합금 투입기구인 흑연중공봉내에 첨가금속을 가압편에 의해 연속적으로 공급하고 이의 압력에 의해 주금속 용탕으로 새어나가는 첨가금속의 량을 조절함에 따라 합금이 수평연속 주조기에서 장시간 유지되어도 시간경과에 따른 조성의 불균형을 즉시 보상해줄 수 있고, 흑연중공봉은 합금투입장치로서의 역할 뿐아니라 중공봉을 회전시키거나 흔들어주는 동작에 따라 합금용탕의 교반효과를 더욱 크게 하여 균일한 조성의 합금을 얻을 수 있는 효과를 나타내게 된다.Therefore, the continuous alloy casting device of the metal of the present invention suppresses a large amount of gas emission generated when the additive metal is mixed with the molten main metal while supplying an inert gas, and in case of the additive metal having a low evaporation temperature, It is possible to reduce the amount of loss and to suppress the environmental pollution in the workplace, and to continuously supply the additive metal into the graphite hollow rod, which is an alloy injection mechanism, by pressing pieces, and to control the amount of the additive metal leaking into the molten metal by the pressure thereof. Therefore, even if the alloy is maintained in a horizontal continuous casting machine for a long time, the imbalance of the composition can be compensated immediately over time, and the graphite hollow rod not only functions as an alloy injection device but also stirs the stirring effect of the molten alloy by rotating or shaking the hollow rod. To make the alloy even more large, to obtain the effect of obtaining an alloy of uniform composition. do.
