그러나 유압실린더은 용강의 고열에 의해 유압오일이 발화될 수 있고, 실린더 내부의 패킹이 소손 또는 경화 등이 되어 작동이 불가능하게 되는 문제점이 발생되었다.However, the hydraulic cylinder has a problem that the hydraulic oil can be ignited by the high temperature of the molten steel, the packing inside the cylinder is burned out or hardened, such that the operation is impossible.
따라서 종래에는 이러한 문제점을 개선하기 위하여 유럽등에서는 래들의 정련과정중 VOD, VCD, VT 등 진공베셀내의 래들을 사용할 경우 슬라이딩노즐 작동용 유압실린더를 착탈식으로 운영하고 있다.Therefore, conventionally, in order to improve such a problem, in the case of using ladles in vacuum vessels such as VOD, VCD, and VT during the ladle refining process, the hydraulic cylinder for sliding nozzle operation is detachably operated.
이때 착탈식 유압실린더는 착탈작업에 따른 공정 대기시간이 유발되고, 착탕작업에 필요한 작업인원 및 장치가 추가로 요구되며, 작업의 생산성이 저하되는 문제점이 있다.In this case, the detachable hydraulic cylinder causes a process waiting time according to the detachable work, additionally requires a working person and a device required for the detachment work, and there is a problem in that the productivity of the work is lowered.
본 고안은 유압실린더에 냉각장치를 외장하여 유압실린더의 착탈작업을 생략한 것으로 작업의 생산성을 향상시킬 수 있고, 환경오염을 방지할 수 있는 용강래들에 설치된 유압실린더 냉각장치를 제공함에 그 목적이 있다.The present invention omits the removal work of the hydraulic cylinder by externally installing the cooling device in the hydraulic cylinder to improve the productivity of the work, and to provide a hydraulic cylinder cooling device installed in the molten steel ladle that can prevent environmental pollution. There is this.
