Abstract

본 발명은 철강 및 비철금속의 스라브를 열간압연하여 열간압연판을 제조할시 스라브의 폭을 늘리는 압연방법에 관한 것으로써, 롤의 길이 방향으로 단이져 있는 단차롤을 이용하여 소재의 폭 방향 중심부를 압하(압연)한 후 평행롤에 의해 압연함으로써, 일정 규격의 스라브를 이용하여 다양한 폭의 열연 판재를 제조할 수 있고, 또한 보다 효율적인 에너지 이용을 도모할 수 있을 뿐만 아니라 박 슬라브 경우에도 적용될 수 있는 향상된 폭 늘림 압면 방법을 제공하고자 하는데, 그 목적이 있다.The present invention relates to a rolling method for increasing the width of slab when hot rolled slabs of steel and non-ferrous metal are manufactured. By rolling (rolling) and rolling by parallel rolls, hot rolled sheets of various widths can be manufactured using slabs of a certain size, and can be applied to thin slabs in addition to achieving more efficient use of energy. It is an object of the present invention to provide an improved method of widening pressing.

본 발명은 철강 및 비철금속의 스라브를 폭늘림 압연하는 방법에 있어서, 롤의 길이방향으로 단이져 있는 상, 하부 단차롤을 이용하여 스라브의 폭방향 중심부를 압연한 후 평행롤을 이용하여 압연하는 단차롤을 이용한 폭 늘림 압연 방법을 그 요지로 한다.The present invention is a method of rolling width slab of steel and non-ferrous metal, step of rolling the width center of the slab in the width direction of the slab by using the upper and lower stepped roll is stepped in the longitudinal direction of the roll The width extension rolling method using a roll makes the summary.
