- 박판주조장치를 이용하여 주조된 박판을 열간압연기에서 열간압연하여 초극박 열연판재를 제조하는 방법에 있어서,상기 박판주조장치에서 주조된 박판을 그 내부에서 권취하고, 권취된 코일을 풀어 상기 열간압연기로 공급하고 온도조절이 가능하도록 구성되는 코일박스를 박판주조장치와 열간압연기사이에 설치하여 주조된 박판을 비산화성 분위기에서 권취한 다음, 열간압연기로 보내 압연하도록 구성되는 초극박 열연판재의 제조방법
- 제1항에 있어서, 코일박스내의 온도가 압연재의 열간압연온도 보다 30-100℃높게 유지되도록 하는 것을 특징으로 하는 초극박 열연판재의 제조방법
- 제2항에 있어서, 상기 압연재가 코일박스내에서 10-60분 유지되도록 하는 것을 특징으로 하는 초극박 열연판재의 제조방법
- 제1항에서 제3항중의 어느 한 항에 있어서, 코일박스와 압연기사이에서의 압연재에 걸리는 장력이 1-10kg/㎟가 되도록 하는 것을 특징으로 하는 초극박 열연판재의 제조방법
