Launder On-line De-gas Machine High effectively de-gasing: There are multilevel de-gas design, there are 3 graphite rotor to de-gas so to generate big convection in de-gas box, which makes small air bubbles well distributed, and enlarge the contact area between aluminium liquid and bubble. At the same time, the de-gas box is designed as vaccum one to refuse air into the box for the second pollution, so that improves de-gas efficiency greatly.Low running cost: It is de-gasing on line, which removed the necessary heat system to keep the aluminium temperature, reduced power consumption greatly, and because of de-gasing on line, there is little aluminium remained, so to reduce the waste of aluminium.To make it easy for making different alloy: As the device is designed to de-gas in launder, after every casting, the aluminium are all given out by which avoids different alloy staying in the furnace, and reduces metal waste and improves productivity.Small area occupied, easy operation: The De-gas device has a easy and simple one, especially for small workshop, reduces basic structure rebuilding work, and concerning different customers have different requests on casting qualities, the de-gas can also raise the aluminium liquid go though withour refining on line, so to reduce the producing cost. And easy maintenance.The designation fully considering the maintenance and convenience, as there is no heat device, which removes the failure point, considering easy to change graphite rotors and maintenance, the rotatable muzzle can rotate 180 degrade, so that even the equipment is under maintenance, the production still continuous.
