Abstract

본 발명은 용융된 금속이 금속방출노즐(19)을 매개로 한쌍의 평행한 주조를(16) 사이의 닙으로 안내되어지고, 상기 노즐(19)은 닙부상에 위치되어 닙의 바로 상부에 롤의 주조표면상에 지지된 용융금속주조풀을 형성하고, 주조롤이 회전되어 응고된 금속스트립(20)을 닙으로부터 하방으로 방출하면서 상기 금속은 망간함량이 0.20중량% 이상이고, 실리콘 함량이 0.10중량% 이상이며 전체 알루미늄 함량이 0.01% 미만인 실리콘/망간 진정연강으로 된 금속스트립 연속주조공정.In the present invention, molten metal is guided through a metal ejection nozzle 19 through a pair of parallel castings 16 between the nips and the nozzles 19 are positioned on the nips and rolled directly on top of the nips. The molten metal casting pool supported on the casting surface of the metal was formed, and the casting roll was rotated to release the solidified metal strip 20 downward from the nip, and the metal had a manganese content of 0.20% by weight or more and a silicon content of 0.10. Continuous casting of metal strips made of silicon / manganese mild mild steel with more than% by weight and total aluminum content of less than 0.01%.
