MOLD FOR CONTINUOUS CASTING SLAB

PURPOSE: A mold for continuously casting slab is provided which is capable of preventing cracks on the surface of casting slab and cracks on the chamfer surface by forming a chamfer surface on corners of casting slab and compensating mold inclination of the chamfer surface. CONSTITUTION: The mold comprises a long side mold, and a short side mold(24) slantly installed to adjust width of the casting slab, a main body(24a) and a projection part(24b) for forming chamfer surface on corners of the casting slab are integrally installed at both end parts of a main body of the short side mold, and a surface of the projection part contacted with the casting slab is formed in an inclination plane so that the projection part casts the casting slab in such a way that the casting slab is getting inclined to an inner side as it goes from an upper side to a lower side of the chamfer surface of the casting slab, wherein an inclination ratio of the short side mold is 0.9 to 1.2%, an angle ( ) between an upper contact side (a) with the body of the short side mold at the projection part and an upper side (c) of inclination plane at the projection part is 30 to 60 degrees, and a perpendicular distance (y) from the upper side of the inclination plane at the projection part to a lower side of the inclination plane is 0.54 to 5 mm. 본 발명은 주편의 코너크랙 및 면세로 크랙을 방지하기 위한 슬래브 연속주조 주형에 관한 것이다. 이 주형은 장변 주형(22)과, 경사지게 설치되고 주편폭을 조절하는 단변 주형(24)을 포함하고, 상기 단변 주형(24)에는 본체부(24a)와 주조되는 주편 모서리에 모따기면을 형성하는 돌출부(24b)가 상기 본체부의 양측 단부에 일체로 구비되고, 상기 돌출부(24b)는 주편과 접하는 면이 경사면으로 형성되어 주편의 모따기면이 하방으로 갈수록 내측으로 경사지게 주조하도록 구성된다.
