Description

Technical Field

[0001] The utility model relates to a degassing machine, in particular to a double-station online degassing machine, belonging to the technical field of casting equipment. Background Art

[0002] Liquid aluminum degassing machine, also known as refiner, is a special equipment used to refine liquid aluminum. Its working principle is to use non-toxic inert gas such as nitrogen or argon as refining agent, cooperate with the mechanical rotation of the rotor (with vent holes), and utilize the principle of fluid diffusion to fully disperse nitrogen in the liquid aluminum, prompting hydrogen to quickly escape from the liquid aluminum to achieve the effect of hydrogen removal; at the same time, it causes small inclusions to focus into larger particles, achieving the effect of slag removal.

[0003] Existing degassers typically utilize a single station, resulting in low refining efficiency. Consequently, some skilled artisans have developed dual-rod refining systems. However, these dual rods still refine at only one refining port and can only be operated synchronously, not independently. Furthermore, the existing lifting frame is manually hoisted, requiring significant effort to replace the refined graphite components.

[0004] Based on this, the present utility model is proposed. Utility Model Content
