초록

현재 운영되고 있는 제철소의 열연 공장은 24시간 상시 운전을 하고 있다. 각 공정별 주요 기능을 살펴보면 가열로, 조압연, 사상압연 및 권취 등으로 구성되어있으며, 여기에서 두께 및 폭 압연을 하고 이를 위한 소재의 온도를 조절하는데 큰 기능이 있다. 여기에는 작업의 특성상 고장 및 불량 요소가 상당히 많다. 또한 제품의 출하 이후에도 클레임이 발생하면 조사가 필요한 실정이다. 기존의 각 공정별 두께계, 폭계, 온도계에서의 독립적인 데이터 취득 및 모니터링에 의한 운전은 조업자로 하여금 많은 피로감을 준다. 이를 보완하고자 각 공정의 데이터를 통합해서 기능별로 모니터링하고 향후 작업 결과도 확인할 수 있는 통합 모니터링 시스템의 필요성이 대두되었다. 이에 압연공정 품질모니터링 시스템을 개발함으로서 보다 효율적인 운영이 가능하게 될 것으로 기대한다.

Today, hot rolled mill plant are currently operating 24 hours a day. The main processes of hot-rolled steel mill are Reheating Furnace, Roughing Mill, Fishing Mill and the Down Coiler. In the process checking over the thickness and width of rolled material, temperature control is an important factor. It is quite often the cause of the work breakdown and find a bad elements for product. After the shipping out the product, when a claim occurs requires an investigation. In each process of the conventional thickness gauge, width, and thermometer. Operation by an independent data acquisition and this monitoring is problematic and straining of the operator. The monitoring process the data of each function and incorporate monitoring results can also check future work. The installation of this system will improve our efficiency and productivity. In the rolling process by developing more efficient operating quality monitoring system, this will be made possible.
