Apparatus for continuously growing ingot

A continuous ingot growing apparatus comprising:

• a growth furnace in which a main crucible is positioned in which molten silicon is accommodated to form an ingot;
• a material supply unit configured to supply a solid silicon material for melting into the molten silicon;
• and
• a preliminary melting unit including a preliminary crucible that melts the solid silicon material supplied from the material supply unit and supplies the molten silicon to the main crucible, and a preliminary crucible heating module that heats the preliminary crucible,
• wherein the preliminary crucible includes a body in which the solid silicon material is accommodated, and a beak which is provided on one side of the body so that the molten silicon melted in the body is supplied to the main crucible, and in which the molten silicon moves, and
• an opening is formed in the body so that the molten silicon moves to the beak,
• wherein the body includes a body plate in a form of a container opened upward in a height direction to accommodate the solid silicon material, a first partition provided on one side of the body plate and in which the opening is formed, and a second partition provided on another side of the body plate,
• wherein the preliminary crucible is movable between a first position at which the solid silicon material is accommodated and a second position at which the molten silicon is supplied to the main crucible,
• wherein, in the first position, the preliminary crucible is inclined upward from the second partition to the first partition at a first inclination angle;
• and
• the preliminary crucible moves from the first position to the second position when a height of the molten silicon is higher than or equal to a height of an uppermost end of the opening,
• wherein the beak includes a moving surface opened upward in the height direction to accommodate the molten silicon supplied to the main crucible,
• wherein the moving surface includes a first moving surface extending in a first supply direction toward a center of the main crucible and a second moving surface extending in a second supply direction tangential to a rotational direction of the main crucible, and
• wherein the beak includes a curved surface connecting the first moving surface and the second moving surface to change a moving path of the molten silicon from the first supply direction to the second supply direction, and
• wherein the center of the main crucible is positioned on a longitudinal central axis of the first moving surface.
