Continuous rapid-cooling solidification apparatus

A continuous rapid solidification apparatus, comprising:

• a cooling roll configured to cool a molten metal supplied to an outer circumference surface thereof;
• a crucible configured to supply the cooling roll with the molten metal and having a heater that surrounds the crucible;
• and
• two or more molten metal supplies configured to melt a raw material metal and alternately supply the crucible with the molten metal,
• wherein each of the two or more molten metal supplies comprises an auxiliary crucible chamber configured to include an internal heater and wherein a first auxiliary crucible chamber of the two or more molten metal supplies is disposed on a left-hand side of the crucible and a second auxiliary crucible chamber of the two or more molten metal supplies is disposed on a right-hand side of the crucible;
• a first chamber configured to form a sealed space where the molten metal supplied from the crucible is cooled by the cooling roll;
• a second chamber configured to be formed of a space separated from the first chamber and to form a sealed space where the molten metal is supplied to the crucible by the two or more molten metal supplies;
• a vacuum level controller configured to control a vacuum level of the first chamber;
• a pressure controller configured to control a pressure of the second chamber;
• and
• a controller configured to control the vacuum level controller and the pressure controller so as to increase the vacuum level of the first chamber and the pressure of the second chamber in proportion to an exhausted state of the molten metal supplied to the crucible.
