- 고정롤과 수평이동가능한 롤로 이루어진 쌍롤형 박판제조장치에서의 박판두께제어방법에 있어서,고정롤과 수평이동가능한 롤의 저널의 움직임(Gj(θ))과 롤 배럴 움직임(Gg(θ+π))을 측정하는 단계와,저널의 움직임Gj(θ)과 롤배럴움직임Gg(θ+π)의 관계, Gg(θ+π)=E(θ+π)+Gj(θ)(여기에서, E(θ+π)는 롤편심에 의하여 나타나는 롤배럴의 움직임이다)로부터 E(θ+π)를 산출하고, 상기 E(θ+π)와 180。의 위상차를 갖는 롤닙에서의 편심에 의한 움직임E(θ)를 구하여 상기 롤닙의 편심에 의한 움직임(E(θ))과 저널의 움직임(Gj(θ))의 합으로 나타나는 롤닙의 움직임을 예측하는 것에 의해 고정롤에서의 롤닙의 움직임Mfcr(θ)과 이동가능한 롤에서의 롤닙의 움직임Mmcr(θ)을 예측하고, 상기 예측된 롤닙의 움직임의 차Mfcr(θ)-Mmcr(θ)로부터 롤닙 갭의 변화량(Mdiff(θ+π))을 산출하는 단계와,상기 롤닙 갭의 변화량Mdiff(θ+π)을 감소시키는 방향으로 박판두께를 제어하는 단계로 이루어짐을 특징으로 하는 쌍롤형 박판제조장치에서의 박판두께제어방법.
- 고정롤과 수평 이동 가능한 롤 각각의 롤배럴 움직임을 검출하는 제1,2비접촉식 거리센서와, 상기 고정롤과 수평이동 가능한 롤사이의 저널움직임을 검출하는 접촉식 거리센서를 구비하는 쌍롤형 박판제조장치에서의 박판두께 제어방법에 있어서,주조 롤이 회전하면서 나타나는 롤의 편심 및 롤 센터의 웁직임을 예측하기 위하여 제1,2비접촉식 거리센서로부터 출력되는 고정롤과 수평이동가능한 롤 각각의 롤 배럴 움직임을 나타내는 신호와, 상기 접촉식 거리센서로부터 출력되는 저널갭의 변화량을 나타내는 신호를 검출하는 단계와,상기 한 롤 배럴 움직임을 나타내는 신호에서 저널갭의 변화량을 감산한 후, 180。 위상반전하고, 여기에서 다시 저널갭의 변화량을 감산한 후, 이 값에서 상기 다른 롤배럴움직임을 나타내는신호를 180。위상반전하여 된 값을 감산하여 롤닙 갭의 변화량을 예측하는 단계와,상기와 같이 구해진 롤닙 갭의 변화량을 감소시키는 방향으로 보상분을 산출하는 단계로 이루어짐을 특징으로 하는 쌍롤형 박판제조장치에서의 박판두께 제어방법.
- 제2항에 있어서,상기 산출된 보상분을 고속푸리에변환한 후, 1차∼3차 주파수성분만을 추출함으로써 고주파성분을 제거하는 것을 특징으로 하는 쌍롤형 박판제조장치에서의 박판두께 제어방법.
