Abstract

본 발명은 연속식 로안의 강철재의 처리상태를 제어하는 방법 및 장치에 관한 것이다.The present invention relates to a method and apparatus for controlling the treatment of steel in a continuous furnace.

제어장치에서 출열기준계수(QOUT(C))와, 두개의 입열기준계수(QC(C)) 및 (QC(C))가 열풍온도 기준값(TFS)을 토대로 열평형의 회귀계산에 의해 최초로 계산된다.The heat output reference coefficient (Q OUT (C)), the two heat input reference coefficients (Q C (C)), and (Q C (C)) in the control unit calculate the heat balance regression based on the hot air temperature reference value (T FS ). Is calculated first.

다음, 재료의 처리상태는 이들 기준계수, 즉 로안의 실제 열풍온도(TFA) 및 실제선속도(LSA)를 이용하여 계산된다.The processing condition of the material is then calculated using these reference coefficients: the actual hot air temperature (T FA ) and the actual linear velocity (LS A ) of the furnace.

출열기준계수(QOUT(C)) 및 두개의 입열기준계수(QC(C)) 및 (QR(C))의 계산이 제1계산기에 의해 계산되는 반면, 다음 계산을 규칙적인 시간 간격으로 계산되는 실제 열풍온도(TFA)와 실제선속도(LSA)를 이용하는 제2계산기에 의해 수행된다.While the calculation of the heat output reference coefficient (Q OUT (C)) and the two heat input reference coefficients (Q C (C)) and (Q R (C)) is calculated by the first calculator, the next calculation is performed at regular time intervals. It is performed by a second calculator using the actual hot air temperature (T FA ) and the actual linear velocity (LS A ), which are calculated as.
