Claims (6)
- 삭제
- 축심을 중심으로 하여 회전하는 주형에 용융금속을 주입함에 있어서, 주입을 개시할 때부터 응고를 완료할 때까지의 사이에, 주형의 회전수를 강제적으로 변동시키며, 그 회전수를 주입재료의 외표면에 부하되는 원심력의 증감속도가 0.5∼30G/s가 되도록, 연속적 또는 단속적으로 복수회 변동하도록 제어하는 것을 특징으로 하는 원심주조방법.
- 제2항에 있어서,상기 주형의 회전수를 강제적으로 변동시킬 때, 그 변동폭을 대응 원심력 차이가 3∼50G가 되도록 제어하는 것을 특징으로 하는 원심주조방법.
- 삭제
- 제2항 또는 제3항의 원심주조방법을 포함하는 원심주조제 롤의 제조방법.
