The present invention relates to a device for manufacturing an ingot and a method for manufacturing a silicon carbide ingot by using the same. The device for manufacturing an ingot comprises: a crucible body which includes an opening unit and accommodates a raw material; and a cover assembly which is positioned in the opening unit and allows at least a portion to be fixed to the crucible body. The cover assembly includes: an arrangement hole which is upwardly and downwardly penetrated; a boundary member which covers the circumference of the arrangement hole and is arranged along the circumference of the opening unit; and a core member which is positioned in the arrangement hole and is upwardly and downwardly moved based on the boundary member. The present invention provides a high-quality single crystal ingot having a large diameter by applying the device for manufacturing an ingot.;COPYRIGHT KIPO 2020
