- 고로의 장입 표면위에 장입물을 분산하기 위한 회전 또는 진동 분산 스파우트를 갖는 고로의 장입 제어방법에 있어서, 고로는 호퍼로부터 스파우트로의 장입물의 흐름을 조정하는 투입밸브를 각각 구비하고 장입물의 저장을 위한 상기 고로 위의 하나이상의 호퍼 및 호퍼의 내용물을 측정하기 위한 중량 시스템을 포함하며, 이 중량 시스템은 호퍼의 내용물이 주어진 시간내에 유출되도록 초기에 밸브가 개방되어야 하는 정도를 결정하고, 각기 다른 종류의 장입물과 각기 다른 장입조건에 대하여 소정의 일정 유출량에 대한 이론곡선과 주어진 시간내에 유출을 확실히 하는데 요구되는 투입밸브의 대응 개폐에 대한 이론 곡선을 기억하며, 이들 곡선은, 매순간마다 투입밸브의 개폐와 참고유출량 Qc를 나타내며, 단위 시간 t단 호퍼 내용물의 중량감소 p를 측정함에 의하여 주어진 간격에 장입물의 실제 유출량 Qr을 측정하고, 실제 유출량 Qr과 참고 유출량 Qc를 비교하며, 실제 유출량 Qr이 참고 유출량 Qc이하일때마다 투입 밸브를 개방하고, 실제유출량 Qr이 참고 유출량 Qc이상일때마다 투입밸브를 패쇄하는 단계를 포함하는 고로의 장입제어방법.
- 제 1 항에 있어서, 상기 투입 밸브의 초기 개방은 상기 결과에 따른 유출량이 계산된 참고 유출량 Qc에 대응하도록 선정되는 고로의 장입제어방법.
