Description

베륨동의 연속주조장치{CONTINUOUS CASTING APPARATUS OF BE-CU}Continuous casting device of Berium copper {CONTINUOUS CASTING APPARATUS OF BE-CU}

본 발명은 베륨(Be)동의 연속주조장치에 관한 것으로서, 특히 용해로에서 용해된 구리용탕을 공기와의 접촉없이 보온로로 이송되게 하되, 용해로와 보온로 사이에 구성된 용탕이송로의 개폐를 실린더의 스톱바 및 스톱바에 의해 정체되어 냉각경화된 용탕경화물에 의해 완벽한 밀폐가 이루어질 수 있게 한 것이다.The present invention relates to a continuous casting apparatus of copper (Be) copper, in particular, the molten copper melted in the furnace to be transported to the heating furnace without contact with the air, the opening and closing of the molten metal conveying furnace configured between the melting furnace and the heating furnace of the cylinder It is stagnated by the stop bar and the stop bar to allow complete sealing by the molten hardened product.

베륨(Be)동의 일반적인 제조방법은 용해로에서 동소재를 녹인 다음 보온로에 투입하는 과정에서 용탕이 대기중에 노출되므로 용탕 내에 산소가 혼입되어 양질의 베륨동 제조가 곤란하게 되고, 따라서 보온로에 투입된 용탕내의 탈산소를 위하여 카본분말이나 질소를 투입하여 처리하고 있으나 고품위의 베륨동 제조에는 어려움이 있는 것이었다.In general, the method of manufacturing belium (Be) copper melts the copper material in the melting furnace and then exposes it to the atmosphere in the process of injecting oxygen into the atmosphere. Carbon powder or nitrogen was added for the treatment of deoxygenation in the molten metal, but it was difficult to produce high quality berium copper.

이러한 단점을 시정하기 위한 수단으로서 용해로와 보온로를 상하로 설치하고, 상기 용해로 하단에 구성된 용탕출구를 카본소재로 된 스토퍼를 이용하여 개폐토록 하는 베륨동 제조장치가 제공된바 있으나, 2~3회정도 사용하게 되면 카본소재로 된 용해로와 스토퍼가 산화되어 공기차단이 어렵게 되므로 베륨동 제조에 장애의 요인이 되므로 통상적으로 2~3회 사용후 스토퍼나 용해로를 교체하여야 하는 단점이 있는 것이었다.As a means for correcting the above disadvantages, there has been provided a beryl copper manufacturing apparatus for installing the melting furnace and the heating furnace up and down and opening and closing the molten metal outlet formed at the bottom of the melting furnace using a stopper made of carbon. When used to the extent that the melting furnace and the stopper made of carbon material is difficult to block the air because it becomes a barrier to the production of copper copper, there was a disadvantage that usually need to replace the stopper or melting furnace after 2-3 times.

상기한 구성 외에도 용해로와 보온로 사이의 용탕이송로가 아닌, 보온로 하단에 구성된 배출구에 스톱바를 설치하여 일측에 구성된 실린더에 의해 보온로의 배출구가 개폐되도록 하여 보온로에 저장된 용탕이 배출구를 통하여 주형으로 공급되게 한 수단이 특허 제661631호 "수직 반연속 주조용 보온로"로 제공된 것이 있다.In addition to the above configuration, the stop bar is installed at the outlet configured at the bottom of the heating furnace, not the molten metal furnace between the melting furnace and the heating furnace, so that the outlet of the heating furnace is opened and closed by a cylinder configured at one side, and the molten metal stored in the heating furnace is discharged through the outlet. Means which have been supplied to the mold have been provided in patent 661631, "Thermal furnace for vertical semicontinuous casting."

그러나 상기한 수단의 보온로 배출구 개폐수단은 배출구의 내경과 거의 비슷한 외경을 갖는 스톱바가 배출구를 출입하면서 주형으로 공급되는 통로가 개폐되게 하고 있으나 잦은 사용으로 인하여 배출구 내경과 스톱바 외경이 마모되면 그 사이에 틈이 발생하게 되고, 상기 틈을 이용하여 용탕이 흘러내리거나 공기가 유입되므로 이상적인 작업이 이루어질 수 없게 되는 문제가 있어 현실적으로 적용되고 있지 못하는 것이다.However, the heat-opening outlet opening and closing means of the above-described means allows the stop bar having an outer diameter almost similar to the inner diameter of the outlet to open and close the passage supplied to the mold as it enters and exits the outlet. There is a gap between them, because the melt flows or air is introduced by using the gap there is a problem that the ideal operation can not be achieved is not applied in reality.

본 발명은 이러한 종래의 제반 단점을 시정하고자 베륨(Be)동 제조를 위하여 용해로에서 용해된 구리용탕을 용탕이송로를 통하여 보온로로 이송, 저장되게 하였다가 보온로 하단 일측에 장치된 수평연속주조장치를 통하여 베륨동제품이 제조되게 하되, 용해로와 보온로 사이에 구성된 용탕이송로의 밀폐가 완전하게 이루어질 수 있게 구성함으로서, 용탕의 누출 및 외부공기와 접촉되는 현상을 방지하여 이상적인 베륨동의 제조가 이루어질 수 있게 한 것이다.The present invention is to correct the above drawbacks of the conventional copper molten copper in the melting furnace for the manufacture of the copper (Be) copper to be transported and stored in the heating furnace through the molten metal furnace and horizontal continuous casting installed on the lower side of the heating furnace The beryl copper product is manufactured through the device, but the sealing of the molten metal conveying path formed between the melting furnace and the heating furnace can be completely completed, thereby preventing the leakage of the molten metal and the phenomenon of contact with external air, thereby making the ideal copper copper production. It was made possible.

이때 전후방수평이송로(63)(64) 사이에 구성된 경사면(65)과, 스톱바(70)의 경사면(71) 사이에 구성된 경사공간부(77)는 후방수평이송로(64) 선단부 일부에도 얇은 폭으로 구성되게 함으로서, 경사공간부(77) 내에 채워진 용탕이 냉각경화되면서 수평용탕이송로(62)과 가능한 넓은 면적으로 접촉경화되게 하여 밀폐성을 향상시킴과 동시에, 경사공간부(77) 내에 충진되어 냉각경화되는 용탕(93)의 두께를 얇게 하여 용탕이송을 위하여 냉각경화된 용탕(93)을 다시 용해시키고자 할 때 보다 신속한 용해가 이루어질 수 있게 하는 것이다.At this time, the inclined surface portion 65 formed between the front and rear horizontal feed passages 63 and 64 and the inclined space portion 77 formed between the inclined surface 71 of the stop bar 70 may also be part of the rear horizontal feed route 64. By having a thin width, the molten metal filled in the inclined space 77 is hardened in contact with the horizontal molten metal conveying path 62 as much as possible while improving the sealing property, and at the same time, the inside of the inclined space 77 is improved. The thickness of the melt 93 which is filled and cooled and hardened is made thin so that the melt can be more quickly dissolved when the melt hardened 93 is melted for transferring the melt.

상기한 상태에서 용해로(10) 내에 투입된 동재료의 용해가 완료되면 용탕(93)을 보온로(30)로 이송시키게 되며, 용해로(10)에 채워진 용탕(93)을 보온로(30)로 이송시키는 작동은 다음과 같이 이루어지게 된다.When the melting of the copper material introduced into the melting furnace 10 in the above state is completed, the molten metal 93 is transferred to the thermal furnace 30, and the molten metal 93 filled in the melting furnace 10 is transferred to the thermal furnace 30. The loading operation is performed as follows.

먼저 수평용탕이송로(62) 내에서 냉각경화된 용탕(93)을 용해시키기 위하여 냉각 및 가열관체(68)에 전원을 인가시키면, 전류가 냉각 및 가열관체(68)를 따라 흐르면서 유도전류가 발생, 수평이송관체(61)를 가열시키게 되므로 수평이송관체(61) 내에 냉각, 경화된 용탕(93)을 다시 용해시킨다.First, when power is supplied to the cooling and heating tube 68 in order to dissolve the cold hardened molten metal 93 in the horizontal melt transfer path 62, an electric current flows along the cooling and heating tube 68 to generate an induced current. Since the horizontal feed tube 61 is heated, the cooled and hardened molten metal 93 is dissolved in the horizontal feed tube 61 again.

냉각 및 가열관체(68)에 의해 냉각경화된 용탕(93)의 용해가 완료되면 작동실린더(73)를 작동시켜 스톱바(70)가 후진, 출구(66)가 개방되게 하면 용탕(93)은 자중에 의해 도 5에서와 같이 수직이송관체(80)의 수직용탕이송로(81)를 통하여 보온로(30)로 이송된다.When melting of the melt 93 cooled and hardened by the cooling and heating tube 68 is completed, the actuating cylinder 73 is operated to stop the stop bar 70 backward and the outlet 66 to open. 5 is transferred to the heat-retaining furnace 30 through the vertical molten metal conveying path 81 of the vertical conveying pipe body 80 as shown in FIG.

상기 이송과정에서도 용탕(93)운 외부공기와의 접촉이 완전히 차단되므로 공기접촉으로 인한 산화현상이 방지된다.In the transfer process, since the contact with the molten external air is completely blocked, oxidation due to air contact is prevented.

상기에서와 같이 용해로(10)에서 용해된 용탕(93)이 보온로(30) 내로 이송이 완료되면 작동실린더(73)를 작동시켜 스톱바(70)에 의해 출구(66)를 차단, 공기와의 접촉가능성을 차단케 함과 동시에 다음 작업을 준비하게 된다.As described above, when the molten metal 93 dissolved in the melting furnace 10 is transferred to the thermal furnace 30, the operating cylinder 73 is operated to block the outlet 66 by the stop bar 70. You will be prepared for the next task while blocking the possibility of contact.

보온로(30)에 이송된 용탕(93)은 보온로(30) 일측에 구성된 연속주조장치(40)를 통하여 베륨동제품(94)을 주조하게 된다.The molten metal 93 transferred to the thermal furnace 30 casts the copper product 94 through the continuous casting apparatus 40 configured at one side of the thermal furnace 30.

상기 주조과정을 간략히 설명하면, 먼저 수평연속주조장치(40)에 설치된 냉각기(35)를 통하여 다이스(33)가 냉각되게 하고, 상기한 상태에서 보온로(30) 하단에 구성된 배출로(34)를 통하여 용탕(93)이 이송되게 하면 상기 냉각기(33)의 냉각수단에 의해 다이스(33)를 통과하는 용탕이 경화되면서 베륨동제품(94)이 성형되고, 성형된 제품은 인출기(도시안됨)를 통하여 외부로 인출되게 한 다음 필요한 길이로 절단되게 함으로서 본 발명에서 제공하고자 하는 베륨동제품의 주조가 완료된다.To briefly explain the casting process, first, the die 33 is cooled through the cooler 35 installed in the horizontal continuous casting apparatus 40, and the discharge passage 34 configured at the bottom of the heat retention furnace 30 in the above state. When the molten metal 93 is transferred through the die, the molten metal passing through the die 33 is cured by the cooling means of the cooler 33 to form a beryl copper product 94, and the molded product is a drawer (not shown). The casting of the beryl copper product to be provided in the present invention is completed by allowing it to be drawn out to outside and then cut to the required length.

이상에서 설명한 바와 같이 본 발명은 용해로(10)에서 용해된 용탕(93)을 보온로(30)로 이송되게 하되, 용탕이송로개폐장치(60)를 통하여 용탕의 누수 및 외부공기와의 접촉현상을 완전하게 차단되게 함으로서 고품질의 베륨동제품을 주조할 수 있게 된다.As described above, the present invention allows the molten metal 93 dissolved in the melting furnace 10 to be transferred to the thermal furnace 30, but leaks of the molten metal and contact with external air through the molten metal conveying channel opening and closing device 60. It is possible to cast high-quality belium copper products by completely blocking the.
