Claims (1)

강의 연속 주조조업에 있어서, 아르곤 자동제어장치인 마이콤과 각종 주조데이타 송수신부를 이용하여 침적 노즐막힘 방지와 주편의 표면 품질 개선을 위해 주조초기에서 주조 완료시까지 래들에서 몰드간 각 아르곤 취입개소에 아르곤 가스를 조업조건에 따라 동적으로 자동제어 할수 있도록 한것을 특징으로 하는 아르곤 유량 자동제어 방법.In the continuous casting operation of steel, argon gas is applied to each argon injection point from the ladle to the mold from the initial casting to the completion of casting in order to prevent clogging of nozzles and improve the surface quality of cast steel by using the microcomputer arbor automatic control device and various casting data transmitting and receiving parts. Argon flow automatic control method characterized in that the automatic control according to the operating conditions dynamically. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
