The invention provides a refining and degassing technology for aluminum ingot melting, and relates to the field of aluminum ingot processing technologies. The refining and degassing process for aluminum ingot melting comprises the following steps: melting a raw material aluminum ingot, sampling and analyzing, timely feeding and adjusting, refining and degassing, introducing inert gas, putting into a rotor to enable molten aluminum to rotate, keeping introducing the inert gas, sampling and analyzing again, and feeding and adjusting. Through the process steps of adding an aluminum ingot for melting, keeping the temperature at 700 DEG C, sampling and testing components, adjusting charging under the condition that the requirements are not met, heating to 730 DEG C, refining and degassing, sampling and testing, adjusting charging under the condition that the requirements are not met, and melting soup into a liquid transfer bag for degassing, when the aluminum ingot is molten, the aluminum ingot has relatively low
