Abstract

본 발명은 아연도금강판의 생산설비에서 스트립(Strip)의 양측모서리(Edge)에 잔류하는 수분이나 크롬(Chrome)용액을 제거하는 이물질 제거용 공기분사시스템 (Air Wiping System)에 관한 것으로, 보다 상세히는 산세척 설비의 출측과 크롬처리설비의 출측에 공기분사장치를 갖추고, 설비제어 컴퓨터(DCS)를 이용하여 스트립에 고압의 공기를 분사시켜 모서리의 이물질을 제거함으로서 아연도금강판의 품질을 현저히 개선시키도록 된 아연도금강판의 이물질 제거용 공기 분사시스템에 관한 것이다.The present invention relates to an air wiping system for removing foreign substances that removes water or chromium solution remaining on both edges of a strip in a production facility of galvanized steel sheet. Has an air injector at the exit of the pickling facility and the exit of the chrome treatment facility and significantly improves the quality of the galvanized steel sheet by removing foreign matters at the edges by spraying high pressure air to the strip using the facility control computer (DCS). The present invention relates to an air injection system for removing foreign matter from a galvanized steel sheet.

본 발명은 설비제어 컴퓨터가, 용접부 검지센서와 길이 검지센서를 이용하여 스트립의 진행거리를 산출하고, 기억장치내에 입력된 스트립의 폭에 따라서 상기 공기분사노즐을 스트립의 양측모서리로 이동시키며, 자동차단밸브를 개폐시켜 고압의 공기로 스트립의 양측모서리에 부착된 이물질(수분, 크롬용액, 분진등)을 제거시키는 아연도금강판의 이물질 제거용 공기 분사시스템을 제공한다.According to an embodiment of the present invention, a facility control computer calculates a traveling distance of a strip using a weld detection sensor and a length detection sensor, and moves the air spray nozzles to both sides of the strip according to the width of the strip input into the storage device. Provides an air injection system for removing foreign substances from galvanized steel sheets that opens and closes valves and removes foreign substances (water, chromium solution, dust, etc.) from both sides of the strip with high pressure air.
