전기로 커버가 되는 천정에 고정되어 냉각하는 급수 쉬벨의 상기 2포인트는 5포인트, 출구가 되는 상부고정부보다 상부에 위치하게 되는 것으로, 특히 상부고정부 수리시 물이 배출되는 것을 방지하는 트랩 역할을 도모하게 한다. 상기 연결관 13내부에는 체크밸브를 설치하여 배출방향으로만 물이 흐를수 있게 추가로 구성할 수 있다. 상기 체크밸브는 자동밸브로 구성하여 전원이 켜져 있을 경우에만 개방되고, 전원이 오프되면 폐쇄되어 연결관에서의 물 유출을 막을 수 있는 것을 방지할 수 있다. The above 2 points of the water supply shevel that is fixed to the ceiling covered with electricity and cooled are 5 points, which are located above the upper fixing part that becomes the exit, and especially serves as a trap to prevent water from being discharged when the upper fixing part is repaired. to promote A check valve may be installed inside the
본발명에 사용되는 제어기는 송수신부/ 입출력부/ 비교부/ 저장부/ 유압실린더, 자동밸브를 구동하는 구동부/ 제어부를 포함하여 구성된다.The controller used in the present invention includes a transmission/reception unit/input/output unit/comparison unit/storage unit/hydraulic cylinder, and a driving unit for driving an automatic valve/control unit.
또한, 본발명은 전기로 모래투입장치에 관한 것으로, 본발명은 무게측정용 Load Cell이 탱크 하부에 설치된다. 그러므로 센서에 의해 현재 Tank 내부 잔량 확인이 가능하다. 그리고 투입량 조절이 제어부에 의해 가능한 것으로, 자동밸브제어에 의해 래들에의 투입량 가감 조정이 가능하다.In addition, the present invention relates to an electric furnace sand input device, and in the present invention, a load cell for measuring weight is installed in the lower part of the tank. Therefore, it is possible to check the current remaining amount inside the tank by the sensor. In addition, the input amount can be adjusted by the control unit, and the amount added to the ladle can be adjusted by automatic valve control.
제어부는 탱크 로드셀로부터 전송된 신호를 판단하여 현재 모래량을 디스플레이에 표시하며, 설정치 이하이면 모래공급장치의 모터를 구동하게 하여, 모래를 모래공급탱크로 공급받는다. 그리고 설정치를 초과하면, 모래공급탱크로부터의 모래공급을 중지시킨다. 제어부는 현재 모래량에 기초하여 래들에는 모래공급을 자동밸브에 의해 제어하는 것으로, 통상 35kg를 래들에 한 번에 투입한다. The control unit judges the signal transmitted from the tank load cell and displays the current amount of sand on the display, and if it is less than the set value, drives the motor of the sand supply device to receive sand into the sand supply tank. When the set value is exceeded, the supply of sand from the sand supply tank is stopped. The controller controls the supply of sand to the ladle by an automatic valve based on the current amount of sand, and usually puts 35 kg into the ladle at once.
제어기는 송수신부, 입출력부, 비교부, 저장부, 제어부로 구성된다.The controller consists of a transmission/reception unit, an input/output unit, a comparison unit, a storage unit, and a control unit.
송수신부는 제어기에 별도의 통신모듈이 설치되어 서버 내지 작업자 스마트폰과 통신될 수 있다. 입출력부는 디스플레이, 터치스크린, 터치패널을 겸용으로 사용할 수 있다. 저장부는 설정치 등 데이터가 저장되어 있고 또 측정데이타를 저장한다.A separate communication module is installed in the transceiver unit to communicate with the server or worker's smart phone. The input/output unit can be used as a display, touch screen, or touch panel. The storage unit stores data such as set values and also stores measurement data.
본발명은 Pipe Chute 막힘이 없는 것으로, 모래종류에 따라 가중치를 곱하여 생산지, 메쉬 등을 데이터화하여 저장부에 저장하고 모래종류에 따라 상중하로 구분하고 각각 모래에 해당되는 가중치를 곱한다. 그러므로 필요한 모래량을 조절할 수 있다.The present invention has no pipe chute clogging, multiplies weights according to the type of sand, converts the production area, mesh, etc. into data and stores it in the storage unit, classifies it into high, middle and low according to the type of sand, and multiplies the weight corresponding to each sand. Therefore, the required amount of sand can be adjusted.
그리고 작업조건이 비가 오거나 습도가 높을 경우에도 가중치를 곱하여 모래를 더 많이 넣게 한다.And even if the working conditions are rainy or high humidity, add more sand by multiplying the weight.
도면을 보면, 센서가 읽은 탱크내 모래 잔여량 값이 923 kg임을 알 수 있다. 그리고 하부에 자동개폐밸브가 설치되어, 제어부의 지시에 의해 개폐되며 통상 한번에 35kg를 래들에 투입한다. 래들 하부에는 구멍이 형성되어 있어서 녹은 쇳물인 용강이 빠져나오나, 상기 모래에 의해 막은 상태에서 쇳물을 넣으면 모래에 의해 하부로 빠지지 않고, 이를 턴디쉬에 용강을 공급할시는 하부의 Slide Gate를 열어 막힌 모래가 빠지며 용강이 턴디쉬에 주입된다. Looking at the drawing, it can be seen that the value of the residual amount of sand in the tank read by the sensor is 923 kg. And an automatic opening/closing valve is installed at the bottom, and it is opened and closed by the instructions of the control unit, and usually 35kg is put into the ladle at a time. A hole is formed in the lower part of the ladle, so that the molten steel, which is molten iron, escapes. The sand is removed and the molten steel is injected into the tundish.
그리고 본발명은 턴디쉬 스프레시 커버 구동장치에 관한 것으로, 본발명의 Air 실린더 전,후진 동작 시점에 대해 설명하면, 본발명은 Air 실린더를 장착하여 4개의 조작레버를 각각 작동시킴으로써 각각의 Splash Cover가 동작하도록 되어 있어, Tundish 안착 후 전진시키고, 작업 종료 후 후진시킨 다음 Tundish를 교체하는 구성이다.In addition, the present invention relates to a tundish splash cover driving device, and when the air cylinder forward and backward operation timing of the present invention is described, the present invention provides each splash cover by operating four operating levers with an air cylinder mounted thereon. is set to operate, so the Tundish is seated and moved forward, and the Tundish is replaced after the work is completed and reversed.
Splash Cover는 연주 Tundish 교체 시 작업 전에 작동시켜 위치시킨 후 사용함으로써 조업 중에는 작동시키지 않으며, Tundish 교체 작업 중 작동여부를 확인하여 고장이 발생되면, 고장 조치 완료 후 Splash Cover가 정상 작동되면 조업 실시하게 한다. The Splash Cover is used after being operated and positioned before the work when replacing the playing Tundish so that it is not operated during operation, and if a malfunction occurs during the replacement of the Tundish by checking whether it is working, the operation is performed when the Splash Cover is in normal operation after the completion of the fault action. .
제어기는 에어실린더를 구동하는 구동부, 터치스크린, 패드 등의 입출력부, 데이터를 저장하는 저장부, 제어부로 구성된다.The controller is composed of a driving unit for driving an air cylinder, an input/output unit such as a touch screen and a pad, a storage unit for storing data, and a control unit.
본발명은 상황에 따라 실린더로부터 돌출되는 로드의 각각 길이를 조절하여 턴디쉬 스프래시 커버를 전체적으로 일정방향으로 기울어지게 하여 래들이나 턴디쉬의 경사각, 곧 기울어진 정도에 맞추게 할 수 있다. 상기 기울기가 설정치를 초과하면 제어기의 제어부는 위험한 것으로 판단하여 경보수단인 스피커를 통해 경보음을 발생시킨다. According to the present invention, the length of each rod protruding from the cylinder is adjusted according to circumstances so that the tundish splash cover is tilted in a certain direction as a whole to match the angle of inclination of the ladle or tundish, that is, the degree of inclination. If the slope exceeds the set value, the control unit of the controller determines that it is dangerous and generates an alarm sound through a speaker as an alarm means.
각 턴디쉬 스프래시 커버들에는 압력센서들이 각각 설치되어 각 스프래시 커버의 압력들을 센서에서 측정하여 제어기의 제어부로 전송하고 제어부는 각 스프래시 커버의 측정값이 설정치보다 크게 차이가 나는 경우 스프래시 커버들 사이에 틈이 발생하거나, 스프래시 커버 하나가 손상된 것으로 판단하여 경보수단인 스피커를 통해 경보음을 발생시킨다. 상기 제어기는 터치패드, 터치스크린 등의 입출력부, 송수신부, 데이터를 저장하는 저장부, 제어부를 포함하여 구성된다. 또한 이산화탄소 등 유해가스 탐지센서가 턴디쉬 스프래시 커버 외부표면에 설치되어 스프래시 커버를 닫은 상태에서도 계속 유해가스가 측정되면, 제어부는 마찬가지로 스프래시 커버들 사이에 틈이 발생하거나, 스프래시 커버 하나가 손상된 것으로 판단하여 경보수단인 스피커를 통해 경보음을 발생시킨다.Pressure sensors are installed on each tundish splash cover, and the pressure of each splash cover is measured by the sensor and transmitted to the control unit of the controller. It is determined that a gap is generated between the covers or that one of the splash covers is damaged, and an alarm sound is generated through a speaker as an alarm means. The controller includes an input/output unit such as a touch pad and a touch screen, a transmission/reception unit, a storage unit for storing data, and a control unit. In addition, if a sensor for detecting harmful gases such as carbon dioxide is installed on the outer surface of the splash cover of the tundish and continues to measure harmful gases even when the splash cover is closed, the control unit similarly creates a gap between the splash covers or removes one of the splash covers. It is determined that is damaged, and an alarm sound is generated through a speaker, which is an alarm means.
본발명의 제어기는 전기로 천정 승강 급수 쉬벨 죠인트 동작을 위한 제어기를 별도 구성하고, 턴디쉬 스프래시 커버 제어기와 래들모래투입장치 제어기를 각각의 제어기로 구성하여 단독제어할 수 있으나, 하나의 제어기로 구성하여 통합제어 할 수 있다.The controller of the present invention separately configures a controller for the operation of the electric furnace ceiling lifting water supply shevel joint, and configures the tundish splash cover controller and the ladle sand dispenser controller as separate controllers to individually control, but with one controller can be integrated and controlled.
따라서 본발명은 Flange 인근 꺾임부분에서 비틀림 응력 집중, 파열현상이 감소되어 고장이 없고 하자보수가 편리한 현저한 효과가 있다.Therefore, the present invention has a remarkable effect of concentrating torsional stress and rupture at the bent portion near the flange, so that there is no failure and defect repair is convenient.
