Claims (3)

  1. 본문에서 설명한 바와 같이
    위 특정지역 중심 등의 "현무암"등의 소재 자체를 괴상이나 분말로 하여 이것을 본문에서 기술한 바와 같은 (1)-(5) 단계의 길이로 등분하여 길이(1)로부터 차례로 전기로의 하부에서 상부로 투입 용해하여 "현무암"등 투입량의 20∼40% 철제련 효과를 얻는 제련방법.
  2. (1)항에 있어서, "현무암"등의 량을 SC 37종철의 10∼60% 범위에 본문기술과 같이 "현무암" 등을 (1)-(5)길이로 등분하여 길이(1)로부터 차례로 전기로의 하부에서 상부로 SC37종철과 적절히 섞어 투입하여 용해 혼합시킴으로서 제련 효과를 얻어 "현무암"등의 투입량의 25∼45%의 철 증산을 하는 제련 방법.
  3. (2)항에 있어서, 제련방법에 더하여 회토류강 공정에서 "현무암" 등에 함유되어 있는 회토류의 원소의 60∼80%가 기존 SC37종철 및 신제철과 서로 침투 합급되도록 하는 회토류강의 제강방법.
