Abstract

The invention discloses a system for removing hydrogen in molten aluminum. The system comprises a molten aluminum tank, a communication tube and a double-cavity type degassing tank, wherein the molten aluminum tank is communicated with the double-cavity type degassing tank by the communication tube; the double-cavity type degassing tank comprises a vacuum cavity and a molten aluminum cavity, wherein a partition plate is arranged between the vacuum cavity and the molten aluminum cavity; a through hole is formed in the middle part of the partition plate; the vacuum cavity is arranged above the molten aluminum cavity; an electromagnetic oscillating coil is arranged outside the molten aluminum cavity; a rotary drive coil is arranged outside the electromagnetic oscillating coil; a liquor taking tube is arranged on the lower part of the molten aluminum cavity; a valve is arranged on the lower part of the liquid taking tube; a gas pumping tube is arranged on the upper part of the vacuum cavity; a gas filling cavity enclosed by a ceramic filter plate and the inner wall of the molten aluminum tank is arranged inside the molten aluminum tank; a gas filling tube is arranged below the gas filling cavity; one end of the gas filling tube extends into the gas filling cavity; the other end of the gas filling tube is arranged outside the gas filling cavity. The system disclosed by the invention adopts the double-cavity type degassing tank, and integrates the technologies, such as electromagnetic driving, ultrasonic-vibration degassing, inert gas removing, spraying and degassing, degassing by centrifugal force, and vacuum degassing, so that the optimal degassing effect is achieved.

Description

technical field [0001] The invention relates to a system for removing hydrogen in molten aluminum on-line. Background technique [0002] Hydrogen forms micropores in aluminum and affects conductivity. In order to improve the conductivity of aluminum, hydrogen removal is a necessary process. Common degassing methods include vacuum degassing (including hydrogen), inert gas degassing (including hydrogen), ultrasonic vibration degassing (including hydrogen), static degassing (including hydrogen), centrifugal degassing (including hydrogen), etc. At present, the industry usually adopts a single method to carry out separately, which has low efficiency and poor effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a system for removing hydrogen in molten aluminum with good hydrogen removal effect, high efficiency and low cost. [0004] In order to solve the above technical problems, the technical solution adopted by ...
