Rapid-cooling solidification apparatus with independently controllable chamber

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;
• two or more molten metal supplies configured to melt a raw material metal and supply the crucible with the molten metal;
• 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 by a chamber partition and the molten metal in the crucible and to form a sealed space where the molten metal is supplied to the crucible by the molten metal supply;
• 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 increase the pressure of the second chamber in proportion to an exhausted status of the molten metal supplied to the crucible,
• wherein each of the two or more molten metal supplies comprises:
• an auxiliary crucible chamber including an internal heater;
• a gate configured to open and close the auxiliary crucible chamber;
• and
• an auxiliary crucible configured to melt the raw material metal in the auxiliary crucible chamber and to be transported toward the crucible when the gate is opened so as to directly supply the crucible with the molten metal,
• wherein the cooling roll moves a cooled material of the molten metal in a certain direction such that the cooled material flows in the certain direction and is rolled up and stored in a storage.
