Description

강의 연속주조 자동 제어방법Automatic Control of Continuous Casting of Steel

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명의 하드웨어 구성도.1 is a hardware configuration of the present invention.

제2도는 본 발명을 설명하기위한 연속주조 설비의 개략도.2 is a schematic diagram of a continuous casting plant for explaining the present invention.

제3도는 본 발명에 따른 주조개시시의 주조 폭별 주조시간별 주조속도 증속 테이블.3 is a casting speed increase table for each casting time by casting width at the start of casting according to the present invention.

제4도는 본 발명에 따른 턴디쉬 교환시의 주조폭별 턴디쉬내 용강량별 주조속도 감속테이블.4 is a casting speed reduction table for each molten steel in the tundish for each casting width during the tundish exchange according to the present invention.

제5도는 본 발명에 다른 주조완료시의 주조폭별 턴디쉬내 잔여 용강량별 주조속도 감속테이블5 is a casting speed reduction table according to the remaining molten steel in the tundish by casting width at the completion of casting according to the present invention

제6도는 본 발명에 따른 주편인발시 주편말단부의 위치별 주조폭별 주조속도 증속테이블.6 is a casting speed increasing table according to the casting width for each position of the cast slab end portion according to the present invention.

Claims (1)

용강감지센서에 의해 감지되는 모올드 내의 제4용강높이(h4)에서 주조될 주편크기에 따른 용강제어장치의 용강유속과 제1용강높이(h1)에서 제5용강높이(h5)까지의 용강 채움시간을 고려하여 주조폭별 주조시간별 주조속도 증속테이블에 따라 주조개시를 자동 제어하고, 턴디쉬교환 작업에 다른 후속턴디쉬 주조초기조건을 확보하기 위해 턴디쉬교환시의 말기주조속도를 0으로 유지하여 주조폭별 턴디쉬내 용강량별 주조속도 감속테이블에 따라 턴디쉬 교환전 주조를 자동제어하고, 주조 완료시 주조 폭별 턴디쉬내 잔여 용강량별 주조속도를 제어하고 턴디쉬내 잔여용강량이 최종값에 이르면 용강제어장치을 폐쇄하고 모올드내의 용강이 제2용강높이(h2)에 이르면 주편인발 작업으로 절환하여 주조폭별 주편말단부 위치별 주조속도 증폭 테이블에 따라 주조를 자동제어 완료하는 것을 특징으로 하는 강의 연속주조 자동제어방법.From the fourth molten steel height (h 4 ) in the mould detected by the molten steel sensor, the molten steel flow rate and the first molten steel height (h 1 ) to the fifth molten steel height (h 5 ) To control the casting start according to the casting speed increase table according to the casting time by casting width by considering the molten steel filling time, and to adjust the final casting speed during the tundish exchange to secure different initial tundish casting initial conditions for the tundish replacement work. Maintained at 0, casting speed by casting width by casting width and casting speed reduction table according to deceleration table, automatic control of casting before tundish replacement, controlling casting speed by remaining molten steel by casting width by casting width, and remaining molten steel in tundish When the final value is reached, the molten steel control device is closed. When the molten steel in the mould reaches the second molten steel height (h 2 ), the molten steel is switched to the cast steel drawing operation. Automatic control of continuous casting of steel, characterized in that the completion of automatic control according to the casting. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
