ASTM B505 Copper Alloy Continuous Casting
STEELMAX Metal Story

ASTM 의 연속주조 (Continuous Casting) 제품
규격은 B505 / B505M 에서 규정하고 있습니다.

ASTM B505 Standard specification establishes requirements for
continuous cast rod, bar, and shapes produced from copper alloys

연속 주조란 생산하고자 하는 Spec에 맞춰진 쇳물 (용강)을
쇳물이 담긴 용기 (레이들, 턴디쉬)를 높은 위쪽에 두고

쇳물을 생산하고자 하는 Size로 된, 주형으로 흘려 보내면
주형 (Mold)을 통과시키면 쇳물이 서서히 응고되면서,

연속으로 생산되는 방법으로,
원하는 길이로 절단하게 됩니다.

사형 주조 (砂型鑄造 : Sand casting) — 모래로 주형 (Mold)을 만들어
사용하는 가장 전통적이고, 많이 사용하는 방법이나

원심 주조 (遠心鑄造 : Centrifugal casting) — 주형 (Mold)에 용강을 주입하면서
회전 시키는, 원심력에 의한 주조 방법으로, 주로 중공 (中空) 제품인

Sleeve, Bushing 제품을 제조할 때 사용하는
생산 방법과는 다른, 또 다른 주조 방법이, 연속 주조 생산 방법입니다.
