Abstract

박주편의 연속 주조방법을 제공한다.A continuous casting method of a stripping piece is provided.

미응고 주편을 롤러 에프론대에서 압하하여 박주편을 제조하는 미응고 압하 연속 주조방법으로서, 하기 ⓛ~②의 공정으로 주조하는 박주편의 연속주조방법.A method for continuous casting under pressure in which an uncoagulated cast slab is rolled by a roller press to produce a foil strip, wherein the continuous casting method is carried out by the following steps (2) to (2).

① 정상 주조속도를 압하후의 박주편이 미응고 압하 존내에서 완전 응고하는 속도까지 일단 저하시키고 ②압하후의 박주편 두께가 압하개시전의 원래의 두께로 복귀한 다음 주조속도를 재차 원래의 정상 주조속도로 중속하여 압하시의 압하력을 해방한다.(1) The normal casting speed is lowered to the full solidification speed in the uncoated solidification zone after the pressure is lowered. (2) The thickness of the thin strip after pressure reduction is returned to the original thickness before the start of the pressure reduction. Thereby releasing the pressing force at the time of pressing.
